Testimonials

Ultra compact for given pressure and flow rates
Flow/pressure combinations within 80 Kw range
– up to 187 l/m or up to 690 bar
All externally exposed components 316 stainless steel
No external lubrication or cooling systems

The high pressure 80Kw type XWJ hydraulic pump is specifically designed for water-based fluids. Separation of the lubricating oil and the pumped fluid is achieved by the installation of a cavity between the cylinder block and the case. Bypass from the pistons is collected in this cavity and returned to the inlet side of the pump. The XWJ pump incorporates six axial pistons actuated by a single rotating swash plate.


Installation

Rotation is bi-directional and the pump may be mounted horizontally or vertically.

A suction filter of 150 microns or better should be used. Finer filtration is desirable for the pump life, but is important that the inlet flowrate to the pump is not restricted and no more than -2 in.Hg is measured in the suction pipework under pumping conditions. Where possible a positive pressure should be maintained in the suction pipework under flowing conditions. When the pump is stationary the suction line should be kept under positive pressure to allow priming.

Important - pumps are delivered from Marshalsea with the case lubricating oil drained. Before the pumps are used, the case should be filled with Castrol Alphasyn PG150 to the level specified on the pump technical data sheet


Material

All external components manufactured from 316 stainless steel – pump shaft is medium carbon steel EN8.
