DL, DLR-type pump Vertical single suction multi-stage segmented centrifugal pump for the delivery of water containing no solid particles and the physical and chemical properties similar to the liquid water used mainly for high building water supply can also be used in factories and mines to Drainage, liquid flow rate of 4.9 ~ 200m3 / h, head range of 22 ~ 239m, supporting the power range of 1.5 ~ 160KW, diameter range of Φ40 ~ Φ150mm.
Model meaning:
80 ------ pump suction nominal diameter (mm)
DL ------ vertical multi-stage centrifugal pump
DLR ------ Vertical multi-stage hot water centrifugal pump
4 ------ pump series
Application:
DL, DLR series pump is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, fire pressurization, long distance water supply, heating, bathroom, boiler heating and cooling water circulation, air conditioning and refrigeration systems, water supply and equipment and other occasions. DL type medium temperature does not exceed 80 ℃, DLR-type medium temperature does not exceed 120 ℃.
Parts Material:
The DL type pump is composed of a motor and a pump. The motor is a Y-type three-phase induction motor. The pump and the motor are connected by a coupling. The whole is a rigid connection, and no correction is needed. The pump consists of a stator part and a rotor part. Pump stator part by the water section, the middle section, guide vane, water section, stuffing box and other parts. In order to prevent the fixed wear, the stator is equipped with a seal ring, a balance sleeve and the like. The worn part can be replaced by a spare part. The rotor part is borne by the shaft, the middle wheel and the balance drum, and the remaining small part residual axial force is supported by the angular contact ball bearings. The water inlet section, the middle section and the water outlet section are sealed by tightening with paper pads. Seal with packing or mechanical seal, the user can choose according to need. Pump rotation direction from the drive side down to counterclockwise rotation.
