Marine & Navy Applications
Marine and naval operations demand pumping solutions that deliver high reliability, compact design, and consistent performance under harsh operating conditions. Delta PD Pumps are extensively used across commercial marine vessels and naval ships for critical fluid handling applications where safety, precision, and durability are essential.
Designed to operate continuously in demanding environments, Delta PD pumps provide smooth, pulse-free flow, excellent handling of high-viscosity fluids, and superior efficiency at varying loads. Their robust construction ensures reliable operation even under vibration, temperature fluctuations, and variable pressures commonly encountered at sea.
Delta PD Pumps support a wide range of onboard systems, including fuel oil transfer, lubrication, hydraulic, and auxiliary services, helping ensure safe navigation, machinery protection, and uninterrupted vessel operation.
Applications
Fuel/Lubricating Oil transfer
Delta PD Pumps—especially triple screw and twin screw pumps—are widely used in the marine and navy industry for the reliable transfer of fuel oil and lubricating oil across critical onboard systems.
These pumps provide smooth, pulsation-free flow, ensuring efficient movement of fuel and lube oils to engines, propulsion systems, and auxiliary machinery. Their ability to handle a wide viscosity range, operate quietly, and deliver high reliability makes them ideal for harsh marine environments.
They are commonly used for:
- Fuel oil transfer between storage tanks and service tanks
- Lube oil circulation for main engines, gearboxes & generator
- Lube oil circulation for main engines, gearboxes & generator
- High-viscosity handling in cold marine conditions

Bilge Water Transfer
Delta PD Single Screw Pumps are widely used for bilge water transfer on ships and naval vessels. These pumps efficiently handle water mixed with oil, sludge, sediments, and debris, making them ideal for bilge wells where fluid conditions are highly variable. Their low pulsation, strong suction capability, and ability to pump contaminated liquids ensure reliable removal of bilge water, preventing flooding risks and maintaining vessel safety and environmental compliance.

Main engine oil lube oil circulation
Delta 3-screw pumps are used as main engine lubricating oil circulation pumps in the marine and navy industry to ensure continuous, reliable
lubrication of main propulsion engines and gear systems. The pump draws lubricating oil from the sump and circulates it through strainers, filters, and oil coolers, delivering clean, temperature-controlled oil to engine bearings, crankshafts, camshafts, and gearboxes.
With their smooth, pulsation-free flow, low noise, and high efficiency, Delta 3-screw pumps maintain stable oil pressure, minimize wear, and support continuous duty operation in demanding marine environments. Their robust design and compact skid-mounted construction make them ideal for commercial vessels, naval ships, and offshore installations, ensuring safe operation and long service life of critical engine components.
Used in :
- Main propulsion engines (2-stroke & 4-stroke marine engines)
- Auxiliary engines & generators
- Gearboxes and propulsion systems
- Navy warships, commercial ships, tankers, and cargo vessels

Fuel feed Pump
Delta PD Pumps—using Triple Screw Pumps and External Gear Pumps—are widely used for fuel feed and transfer operations on marine vessels and naval ships. These pumps ensure continuous, stable, and clean fuel supply to engines, generators, and auxiliary systems.
Key Functions:
- Transfer of diesel, furnace oil, and marine fuel oil from storage tanks to day tanks
- Precise and pulse-free fuel feeding to main engines and generator sets
- Efficient handling of low-viscosity and high-viscosity marine fuels
- High reliability under varying sea conditions, ensuring uninterrupted vessel operation
- Low noise, minimal vibration, and long service life—critical for naval applications
