The high pressure Type XW hydraulic pump is suitable for a wide range of fluids including water-based solutions and oil-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 pump is available with either three or six pistons. The six piston version can be supplied with duplex deliveries which may be used for simultaneous high and low pressure applications when used with an automatic unloading valve. Additional variations are possible by varying the input speed to a maximum of 1,800rpm.

Various combinations of flows and pressures are possible within the 15 kw range up to a maximum of 870 bar (12,750 psi) at 2.8 litres/min (0.7 USg/m) or up to 41.2 l/m (10.8 USg/m) at 220 bar – see table on the right.
Installation
See installation and start up page.
Material
