Type T

APPLICATION

T type pumps are designed to feed the deep mine longwall supports with oil emulsion at high pressure. They are also applicable in any other case when high pressure at low capacity is required.

DESIGN

Triple plunger pumps driven by electric motors via a gear box reducing the speed and a crankshaft. The plungers are led in grease lubricated bushings and sealed by high pressure seals. The hydraulic assembly comprises the suction and delivery valves and the relief and safety valves.
The pumps are compliant with Atex directive.

MATERIALS OF CONSTRUCTION

As standard, the pump is manufactured of cast iron; the other elements are manufactured of cast steel.
