Product Details | AXIAL PISTONS PUMP
4320-00-555-0159 A positive displacement device which utilizes the reciprocating motion of a multiple number of parallel pistons arranged axially in a cylinder barrel as a means of transferring a liquid from one place to another. The pistons are actuated by revolving the cylinder barrel at an angle to the drive shaft axis or by a tilting box when the cylinder barrel revolves on the drive shaft. The piston displacement may be fixed or variable. It is designed to be driven by a prime mover which is not an integral part of the pump.20216500058Aircraft Hydraulic, Vacuum, and De-icing System Components43200020Power and Hand Pumps
