Overview: DK type pump is a two-stage horizontal split centrifugal pump, which is suitable for industrial and urban water supply and drainage, and can also be used for agricultural irrigation and drainage. It is used to transport clean water and other liquids with physical and chemical properties similar to water, and the temperature of the liquid to be transported is -20 to 80 °C. The maximum allowable inlet pressure is 0.6MPa.
Parameter range:
Flow rate Q 18～1368m3/h
Head H 100～360m
Model Description:
40DK130
40--Spit diameter (mm)
DK-indicates multi-level open in the middle
130--pump total head (m)
Structure type:
The pump is opened horizontally. The suction port and the discharge port of the pump are located in the lower part of the pump casing below the open surface of the pump, and are horizontally located on both sides in a vertical direction with the axis line. It is not necessary to remove the motor and pipeline during maintenance, and the operation is very convenient. The shaft is supported by rolling bearings and sliding bearings. Except for the 100DK230 and 250DK240 type pumps, which are lubricated with thin oil, the rolling bearings are lubricated by grease, and the 250DK360 type pump is forced to circulate thin oil for sliding bearings (equipped with thin oil station). The pump shaft seal can be a packing seal or a mechanical seal. Rotation direction: Viewed from the motor side, the 250DK240 and 250DK360 pumps rotate counterclockwise, that is, the suction port is on the left and the discharge port is on the right. The rest are rotated clockwise.
Main parts material:
250DK360 pump body and pump cover are cast steel and cast stainless steel, others are cast iron.
Scope of complete sets: complete sets of supply pumps, motors, bases, check valves, gate valves.
