Barber-Nichols (BN) specializes in pumps for the aerospace industry. Innovative design experience, expertise with exotic materials, and aerospace quality standards make BN an obvious choice for the design and production of aerospace hardware.
BN can custom design a small, fast, and lightweight aerospace pump for your application. The model BNP-21-000 shown above uses a canned motor for a hermetic design water pump that runs a partial emission impeller directly driven by a 28 volt brushless DC motor. Many other similar designs are available for a wide range of fluids and performance.
BN also provides a standard line of time-tested Avionics Cooling Pumps. These pumps are centrifugal designs with close-coupled shafts and integral mechanical seals. BN also specializes in the design and production of customized pumps for a wide variety of other aerospace applications including life support and environmental control.
The Model 744000 Avionics Cooling Pump (NSN: 4320-00-184-9007) is used to cool electrical systems on the C-130 Air Transport. The pump weighs a mere 4.3 kg (9.5 lbs) and circulates a 50/50 mix of either ethylene glycol and water or propylene glycol and water. 400 Hz electrical power drives the pump and it circulates 15 l/min (4 GPM).
The Model 411000 (NSN: 4320-00-050-8205 & 4320-00-152-1488) is used to pump MIL-H-5606 Oil, also on the C-130 Air Transport. This pump is also an extremely lightweight 4.3 kg (9.5 lbs), is driven by 400 Hz electrical power, and circulates 72.7 l/min (19.2 GPM).
Barber-Nichols was awarded a NASA Phase II SBIR to design and produce two 204 m3/hr (900 GPM) liquid oxygen propellant loading pumps. NASA used one 273 m3/hr (1,200 GPM) pump to load liquid oxygen propellant. The two new BN pumps utilize improved, highly reliable shaft seals, and are designed to be piped in parallel. The use of two pumps in parallel will increase the rate at which spacecraft are loaded to 408 m3/hr (1,800 GPM). The pumps are also controlled by variable frequency drives and should one pump go offline, the flow through the remaining pump can quickly be increased to 273 m3/hr (1,200 GPM). If confronted with a mechanical failure, this redundant pump system minimizes launch delays.
