HYDRAULIC OIL PUMPS

Type SM

Type SMLP

Type LM

Type LMLP

Type X

Type X30

Type XH

Rotating swash plate design
Pressures up to 1040 bar
Flows up to 41.27 l/m (10.894 USg/m)
316 stainless and carbon steel case options
Flow/pressure combinations within 15 kw range
Duplex operation option available

The high pressure Type X hydraulic pump is available with either three or six axial pistons actuated by a single rotating swash plate.

The six piston version can also be supplied with duplex deliveries which may be used for simultaneous high and low pressure applications when used in conjunction with an automatic unloading valve. Other output combinations are available.



Various combinations of flows and pressures are possible within the 15 kw range up to a maximum pressure of 1040 bar (15,080 psi) and a flow up to 41.27 litres/min (10.894). See the table below.

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.

Fluids

A mineral-based oil is recommended with additives to resist corrosion, oxidisation and foaming. The operating viscocity should be between 15 and 100 cst. Consult the factory for viscocities outside this range.

Temperature

The operating temperature range is -20°C to +60°C (Ambient)
