Axial Plunger Pump

Axial Plunger Pump is a plunger pump of the rotating swash plate type and is fitted with either three or six plungers. Where six plungers are fitted, they are arranged to discharge in two sets of three. The three plunger model has the plungers spaced in position (A) Section I, Axial Plunger Pumps are identified by size numbers 1, 2 and 4. There is one exception to this rule in the case of the XA4, which is a 6 plunger model, comprising two size 2 sections. For smaller outputs or outputs between these three basic sizes, one or two plungers are rendered inoperative by the size numbers 001' 01, 02 etc. In the first case, two, plungers are inoperative in the others, only one plunger inoperative. The six plunger model has the plungers spaced as Section I. If one set of three plungers is larger than the other, then the larger plungers are spaced in the (A) position, the six plungers model can have all six plungers, combined in a discharge block, fitted to face (X) to discharge through a single part. Axial Plunger Pumps are identified by the size numbers 3, 5 and 6 or in rare cases 2001,201,402 etc. If the six plungers are arranged to discharge in two sets of three through two separate parts in the discharge block, they are identified by the numbering 1/2, 2/4, 001/2 etc. It is possible to combine any single output from three rams with any other, but in practice there is little demand for such combinations, and these are subject to additional charge. The Axial Plunger Pumps are fitted with a through shaft so that other low pressure pumps or a second Axial Plunger Pump can be tandem mounted on the outboard end by housing (80). The Axial Plunger Pump Comprises Four Main Assemblies

• The Boost Pump.
• The High Pressure Pump Body
• The Driving Shaft, Wash member and Wobbler Plate Assembly
• The Pump Drive Housing
