Marine Pumps

Barber-Nichols Marine Pump in S-80 Class Submarine

Since 1972, Barber-Nichols Inc. (BNI) has produced Marine Pumps for high-performance ocean-going vessels. BNI designed and produced self-priming fuel pumps, bilge pumps, macerator pumps, chill water pumps, engine wash pumps, electronics cooling pumps, as well as pumps for fuel cells.

Barber-Nichols Model 815000 Marine Pump in Landing Craft Air Cushion (LCAC)

The Model 815000 Marine Pump (NSN: 4320-01-206-4439) is a gas turbine engine wash pump on the Landing Craft, Air Cushion (LCAC). The unit weighs 15 kg (34 lbs), pumps water at 57 l/min (15 GPM), and is driven by 400 Hz electrical power.

Barber-Nichols Model 817000 Marine Pump in MK-92 Fire Control System (FCS)

The Model 817000 Marine Pump (NSN: 4320-01-304-6924) circulates Coolanol 25, and/or PAO in the MK 92 Fire Control System’s (FCS) Combined Antenna System. The unit weighs 3.9 kg (8.5 lbs), pumps coolant at 26 l/min (7 GPM), and is driven by 400 Hz electrical power.

Barber-Nichols produced cooling/firefighting pumps for Kawasaki’s Jetfoil and for the U.S. Navy’s Pegasus Class Hydrofoil. Each vessel carried two pumps; one is electrically driven and the other is hydraulically driven. The pumps processed seawater and were regularly used for equipment cooling; however, in an emergency, they could be used for firefighting. The use of one electric and one hydraulic powered pump creates a redundant system that is not dependent upon a single power source. In the event a fire damaged the vessel’s electrical system, the hydraulic-powered pump could still be used to control the fire.

Marine pumps designed, or modified, for military applications are subject to the International Traffic in Arms Regulations (ITAR) and may not be exported, released, or disclosed to non-U.S. Citizens inside or outside the United States without prior written approval from the U.S. Department of State.
