Rotary Gear Manual Hand Pump - GPN47741

The GPN47741 bidirectional, corrosion resistant rotary gear hand pump

The Nu-Torque Model GPN47741 corrosion resistant hydraulic hand pump is specifically designed for the marine environment. Constructed of cast nickel aluminum bronze (NAB) housings, stainless steel gears, shafts and hardware suited for areas where corrosion resistance is required. This same selection of materials also creates a hand pump which may be used where non-magnetic properties are required.

The hand pump is designed to meet all of the performance and connection requirements of MIL-P-18111A for manual operated hydraulic systems such as valve actuators and water tight doors.

The hand pump may be used as a single direction hydraulic power source or as a bi-directional pump eliminating the need for a selector valve.

The pump is constructed with metal to metal mating surfaces with O-ring seals between the pump body and the front and back castings. The shaft is sealed with a corrosion resistant mechanical shaft seal. Inlet and outlet ports are SAE-16 (1 inch) straight thread O-ring port configuration.

A removable hand crank with a long, double hand size spinner allows for removal for stowage or passage clearance. Removal of the crank also helps control unwanted or accidental operation.
