Ultra compact for given pressure and flow rates
Flow/pressure combinations within 9 Kw range
– up to 11.5 l/m or up to 1380 bar
All externally exposed components 316 stainless steel
No external lubrication or cooling systems
Direct coupled option with horizontal mounting.

The high pressure 9Kw type LMW 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 LMW pump incorporates three or six axial pistons actuated by a single rotating swash plate.


Installation

Rotation is bi-directional and the pump may be mounted horizontally or vertically. Vertical motor pump units are supplied with a bellhousing and coupling. Horizontal units have the option of direct coupling between the pump and motors from 90 to 112 frame size.

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. High pressure variants use some 17/4 PH externals.
