Diesel engines have been the backbone of the marine industry since the early 1900s. Larger vessels utilize diesel-driven engines due to their simplicity, reliability, and energy efficiency. However, the challenge with this style of engine is often configuring the correct startup sequence to power the engine consistently and safely. This guide will delve into the difference between diesel air and electric start systems, the requirements for the system to operate, and other key applications for compressed air on marine vessels.
What is a start system?
Diesel engine start systems use air or electricity to kickstart the large turbines within the engine into gear. An air start system uses compressed air to directly or directly turn the diesel engine turbines through an air motor. Electric start systems utilize an additional motor that pulls energy from the boat’s batteries.
Electric vs. Air Start Systems
example of an air start system from machineryspaces.com
Air start systems for diesel-driven motors are generally recommended in marine applications, especially for larger vessels. Electric start systems require additional motors and batteries, which take up more floor space and add more weight onboard. The extra motor will siphon energy off from the ship’s main battery. The functionality of this added equipment will vary depending on the ambient temperatures. Having these complex electrical components out at sea puts them at risk of corrosion. Even if it doesn’t touch seawater, the air is humid and salty enough to cause corrosion.
A diesel air start system requires less equipment with less complex electrical components. This lowers the risk of corrosion and ignition sources in and around flammable materials. Air start systems also allow for more safety measures through interlocks. These interlocks are valves set up to block the initial burst of air from reaching the turbines prematurely. The result is additional protection against engine startup accidents and ensuring the correct air pressure is available to turn the turbines. While the properties of compressed air change with temperature, the fluctuations will not be significant enough to prevent the engine from turning on.
Diesel Air Start System Requirements
Building a diesel air start system starts with selecting the suitable compressor and tank combination. It is recommended to size the air tank- or “bottle”- to store enough compressed air for twelve startups when complete. An engine’s operating manual will specify the amount and pressure of air needed to start the specific engine model. This compressor system will also require air treatment to remove dust, water vapor, and flammable oil condensate from the air before it reaches the engine.
Regular air maintenance of this compressor system is as essential as selecting the initial unit and tank. Air tanks must be condensate-free to deliver as much air as possible to the engine. Valves and piping will also need regular inspection to prevent air leaks.
Other Common Compressed Air Uses on Ships
At least one air compressor system is usually already present on a vessel to assist with other necessary processes, including:
Control systems: Compressed air is used for throttle controls, control valves, and engine emission monitoring systems.
Water supply: Compressed air pressurizes hydrophores to distribute water for domestic and sanitary use.
Wastewater treatment: Compressed air powers onboard sewage systems to conduct aerobic sewage breakdown.
Safety features: Compressed air powers safety features like ship whistles, foghorns, and fire pumps.
Pneumatic pumps: Compressed air powers pneumatic pumps to transfer water, oil, and bilge.
Lifeboats: Air motors help heave up lifeboats for crewmen and staff.
Champion Air Compressors
The pressure-lubricated PL-series from Champion exceeds in demanding applications where typical compressors will falter. What sets this series apart is the heavy-duty, rugged design. Both the crankshaft and connecting rod are protected by pressure lubrication to ensure that the compressor oil is used when and where it is precisely needed. The PL-series also offers load-less starting, which provides easy, fast startup. Both of these features work together to extend the life of the compressor.
The PL-series comes in simplex and duplex styles and offers options between 3HP and 30HP. The difference between simplex and duplex builds is the number of pumps in the assembly. A simplex unit will have a pump, motor, and tank assembled in a single package. Duplex units have two pumps and two engines, all mounted together onto a tank. Having two pumps allows for a more consistent air supply. As one pump finishes its cycle, the second will start without reducing air output. Champion also sells the pumps individually for replacements or custom builds. PL-series compressors come with Champion’s standard 3-year warranty; alternatively, Champion also offers a 6-year warranty option with the parts and consumables needed to maintain the machine for an additional 3 years.

It can be challenging to balance the location of onsite compressor systems. They need to be in close proximity for optimal pressure output without occupying excessive space. Many facilities place their compressors outdoors to save floor space and increase airflow. However, this exposes the equipment to the risk of freezing temperatures. Storing equipment inside an air compressor cabinet safeguards your air supply and optimizes vital floor space.
What to Look for in an Air Compressor Cabinet
One important feature to look for in an air compressor cabinet is soundproofing. Air compressors typically produce noise levels of around 85 dBA, depending on factors such as the type of compressor, its horsepower, and how often it is maintained. Prolonged exposure to high noise levels without proper safety measures can lead to hearing loss. According to OSHA, exposure time should be limited to a maximum of eight hours at 90 dBA and two hours at 100 dBA. Installing an air compressor cabinet to reduce the ambient noise levels can help protect onsite employees from hearing loss.
When setting up an outdoor cabinet for your air compressor system, it’s important to ensure that it protects the compressor and piping from extreme weather. Low temperatures can cause any condensation inside the machine and its piping to freeze and expand, which may lead to pipe bursts. Running a compressor without a way to discharge the pressurized air can also cause severe damage, often resulting in the need for premature replacement of the machinery.
While cold weather poses a serious risk to compressors, excessive heat can also impact your compressor’s performance. An overheated compressor produces air that will have a harder time reaching lower dewpoints. This air will contain more condensate, leading to lower pressure output and posing a risk of clogging downstream air treatment.
All Weather Air
All Weather Air provides fully weatherized air compressor cabinet solutions built to protect compressors from weather hazards while providing increased filtration to ambient air. These compressor cabinets come in size options starting as small as four feet up to forty feet, with variable heights and widths depending on need. As a baseline, All Weather Air tests all cabinets to ensure compressors can work in outdoor temperatures of -40°F up to over 120°F.
Cabinets from All Weather Air come standard with one-inch-thick noise insulation on the interior of the enclosure to reduce noise, with a two-inch-thick insulation option available as well. They also have slip-resistant flooring and wide doors with safety latches to give you peace of mind regarding worker safety.

In the mining industry, slurry pumps are crucial for daily operations, whether in the mine itself, refineries, or process plants. It is essential to find pumps that can effectively handle process water, suspended solids, and slurries without the risk of pump failure while maintaining their intended performance standards. Metso provides both horizontal and vertical slurry pump options to meet the diverse needs of its customers worldwide.
Why Choose Metso?
Metso specializes in manufacturing equipment for mining, specifically for aggregate production, mineral processing, and metal refining. All Metso pumps, pipes, and hoses use either a rubber-lined interior or high-chrome alloy material to give abrasive and slurry resistance by default. These designs have been thoroughly tested and refined in the field to ensure that customers have reliable pumps they can depend on. Metso backs all of its equipment by offering extensive technical support options and on-site training opportunities as needed.
Sala VS Series Vertical Sump Pumps
The Sala VS Series vertical slurry pump as we know them combines the original SALA series cantilever build with the wet end design from the Orion series horizontal slurry pumps. This change allows for easier maintenance and part availability and improves the total dynamic head of the pump for better performance.
A common issue vertical pumps face is the parts that may require the most maintenance being submerged in fluids or slurries, making them inaccessible when they require service. Metso side-steps this problem with the cantilever design. Bearings, shaft seals, and the stuffing box are all accessible at the top of the pump.
The impellers for the VS series come in open, semi-open, or closed styles and have two additional agitator options to extend the pump’s capabilities & performance.
Sala VT Series Vertical Tank Pumps
Sala VT series pumps have the same benefits offered by the cantilever design as the Sala VS series and come in a self-contained package with the pump, motor, and tank. This combination allows for greater layout flexibility in any facility and simplifies installation. The open sump and vertical intake combination prevent cavitation or other air blockage by allowing trapped air to run up within the shaft. This also allows the pump to run dry without causing significant damage.
These tank pumps work well in applications such as feeding dewatering cyclones, in mixing applications, and especially stand out where mobility is a concern.
Sala VF Series Vertical Froth Pumps
The Sala VF series vertical froth pump takes from the maintenance-friendly design of the Sala VS series and the simplified layout of the Sala VT series, with one more added benefit. By creating a vortex to separate the entrained air in the slurry, the Sala VF series allows for greater flow rates. Additionally, releasing entrained air removes the risk of cavitation and the damage it can cause in the downstream pump system.
Ironically, the Sala VF series pump can be used to separate lighter substances in flotation froth pumping and can also be used for mixing dry powers with water like in cement production. The VF series also lends itself well to washing stations for minerals like phosphate & apatite.

In many applications, choosing between sliding vane vs gear pumps is not as much of a clear-cut answer as compared to choosing between two other types of positive displacement pumps. Both overlap in the industries they serve and can often perform the same applications. While both will overlap in performance, here are five reasons a facility may choose a sliding vane pump over a gear pump.
1. Self-Compensating Rotors
The working principle behind gear pumps is that a pair of gears push the liquid from the suction port out and around toward the discharge port. Typically, as gear pumps age, the clearance between the gears and even the pump housing increases, leading to lost efficiency or ‘slippage’. Slippage will continue without any intervention until the pump cannot move fluid through the housing. This common problem led to the first Blackmer sliding vane pump back in 1899, which was engineered to improve upon the gear pump’s lifespan and efficiency.
Cutaway of Blackmer HXL8 Pump showing self-compensating rotors
Blackmer uses self-compensating vanes to counteract the wear that gear pumps face. To prevent slippage within sliding vane pumps, Blackmer uses several physical forces to guarantee that the vanes will always maintain positive contact with the pump housing. The first is the rotor’s centrifugal force as it throws the vanes outward towards the pump housing. The second is pressure as the cavities housing the vanes are filled with the liquid. Lastly, in several models, the vanes are attached to the rotor with a spring-loaded pushrod moving opposing pairs of vanes. As the vanes wear over time, these operating principles allow the vanes to self-adjust, preventing slippage and preserving efficiency over the life of the vanes. When noticeable slippage occurs, these vanes can be quickly and easily replaced.
2. Liquid Compatibility
While both vane and gear pumps can work with viscous fluids such as oil or petroleum, sliding vane pumps can also work with:
✅ Thin liquids
✅ Liquid and vapor mixtures
✅ Liquids with suspended solids
Blackmer pumps come in several types of metal to accommodate different chemical compatibility needs. Vanes within the pump come in metallic and non-metallic options to ensure the best compatibility with the application at hand. Blackmer also offers the SX sliding vane series for corrosive and shear-sensitive applications. Check here for a complete liquid compatibility guide for its sliding vane pump materials.
3. Dry-Run Capability
Close-up of a gear pump after running dry
The most significant difference between sliding vane vs gear pumps is the vane pump’s durability, even when not primed. A sliding vane pump can operate dry for several minutes without causing significant damage. Gear pumps have limited self-priming capacity but should never run dry. Without fluid inside the housing, the teeth of the gears will grind and destroy the internal mechanisms of the pump.
4. Coupling Styles & Floor Area Availability
Gear pumps require precise alignment between the shaft moving the gears and the motor. If misaligned, the rotor either pushes the gears into each other where they meet and accelerates wear-and-tear in the pump or pulls them apart, ruining the seal where the gears meet. This fact reduces gear pumps’ coupling styles to close-coupled or mag-driven.
Sliding vane pumps have more versatility in coupling style options. Besides close-coupling available with the GNX series, Blackmer vane pumps can be mag-driven, flex-driven, or belt-driven, as seen in the photo above.
5. Maintenance-in-Mind Design
While both pump styles need regular maintenance, Blackmer engineers its sliding vane pump interiors for easy accessibility for maintenance staff, even while the pump is still on-site. Another feature from Blackmer is the cavitation suppression liner. This component surrounds the rotor and vanes of the pump and breaks apart bubbles into smaller sizes, reducing the risks associated with cavitation.
Gear pumps have a complicated assembly process that requires careful handling during disassembly and reassembly. For example, some gear pump manufacturers design their gear pumps to have the mechanical seal behind the shaft of the pump. As a result, maintenance personnel need to disassemble the pump further for seal installations, removals, and repairs compared to other pump manufacturers. Moreover, this restricts their customers to using only proprietary mechanical seals specifically designed to fit in the space.
When to choose a gear pump?
Although sliding vane pumps have certain advantages over gear pumps, there are situations where gear pumps may be a better choice. For example, the benefits of sliding vane pumps may not apply to every application. For instance, if the pump will always have fluid in the wetted housing, having a self-priming pump becomes unnecessary.
Gear pumps will perform better with high-viscosity fluids due to the lower speeds at which they operate. Furthermore, gear pumps typically have fewer moving components, making identifying problems during service inspections easier.
Blackmer offers gear pumps alongside its industry-renowned sliding vane pumps in its robust portfolio. Blackmer Gear pumps offer 95% interchangeability with competitor pumps all while keeping patented design features unique only to Blackmer Gear. Lastly, Blackmer backs its gear pumps with an unmatched 5-year warranty for its gear pumps.

Aquafighter® is an active tank treatment that removes emulsified water from diesel and biodiesel blended fuel, along with any free water present. Your fuel and tank will be protected from excess water generated over time.
Where and How Water Gets Into Your Tanks
Free and entrained water is generated in your tank through air condensation, fuel supply, ineffective filtration, leaks, accidents, and improper system design. Additionally, when water is allowed to accumulate in your tank it provides the conditions for Microbial Contamination (“diesel bug”) to grow, leading to significant problems including blocked filters, pump damage, engine failures, tank corrosion, and poor fuel efficiency.
Water will likely be present in all diesel fuel systems, including storage and operation. It may exist as free water, visible as a separate layer below the fuel, or as a hazy layer between the water and fuel layers. The layer consists of microscopic droplets of water suspended in the fuel.
Water in Fuel Leads to Microbial Contamination – What Issues Does This Contamination Cause?
Did you know microbiological contamination often creates operational issues that can disrupt the use of an asset? Here are some examples:
Microbial matter builds up in a tank until it renders the tank unusable, requiring cleaning.
Contamination blocks the filters of the generator engine, preventing it from firing up.
A fuel quantity indicator functions incorrectly because of a microbial biofilm coating the probes that read the fuel levels.
How Does Aquafighter work in the fuel tank?
Aquafighter is effective in reducing and removing water inside the fuel tank. This is accomplished through three indispensable actions:
Demulsifies waterby physicochemical adsorption of water molecules to less than 65ppm total fuel water content with maximum efficiency.
Attracts & Captures water immediately upon release from the fuel molecules.
Isolates water in its protective gel to permanently segregate it from the fuel and tank environment so your fuel and tank are protected.
The Benefits:
Prevents diesel bugs from forming.
Works directly in the tank (no fuel removal needed).
Eliminates the need for most additives and minimizes the use of biocides.
Reduces filter replacement by around 60%.
Reduces the need for tank cleaning.
Protects tanks from corrosion.
Exceeds EN590 standards – 100% efficient at reducing water to <75 ppm.
