Type XW 11196/11197/11202
20 HP Hydraulic pump for water/glycol applications



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.

This pump conforms to Directive 94/9/EC relating to equipment intended for use in potentially explosive atmospheres and is ATEX (ATmosphere EXplosible) certified.
Marshalsea Hydraulics has been assessed by SGS Société Générale de Surveillance SA and certified as meeting the requirements of ISO 9001:2000 for the design, development, manufacture and servicing of hydraulic pumps, relief valves and intensifiers.
