Type WT

APPLICATION

WT pumps are designed to handle clear water as well as water containing small solids having a maximum size of 0,5 mm (tiny sand, mule). Temperature of the pumped liquid must not be greater than 40°C, and the density to 1050 kg/m3.

Primary application of WT pumps is pumping drilling mud when large diameter is drilling. Pumps can be used in potentially explosive methane and/or coal dust atmospheres as a device group I category M2.

DESIGN

Double piston single body pumps with mechanical gear train and slider crank mechanism. Discharge system consists of two cylinder heads with cylinder bushings and ball valves, located symmetrically in relation to the body and screwed with body with bolts. Both cylinder heads are connected to an air vessel, used to pressure equalization while pistons are working. Internal moving parts are lubricated by splash oil. Pump has an overflow safety valve, protecting it against excessive pressure.

Pump is mounted with four screws to the ground, which may be a portable frame, the flat surface of another machine or permanent foundation.
