Structure

     The pump is horizontal split casing. The pump inlet and outlet are located under split surface and are horizontally located on two sides of the pump casing; their centerlines are perpendicular to the pump axis. It is unnecessary to disturb the motor and the pipeline for maintenance, so it is very convenient to operate. The pump can use rolling bearing or sliding bearing. All other pumps use rolling bearings which get lubricated with grease except type 100DK230 and 250DK240 pumps with dilute-oil. Type 250DK360 pump uses sliding bearings which get lubricated with enhanced circulation of dilute-oil attached with dilute-oil station.

The direction of rotation

The rotor rotation of type 250DK240 and 250DK360 is counter clockwise looking from the motor to the pump i.e. the inlet is on the left and the outlet is on the right. The rotor rotation of all others is clockwise。

Material of main parts
