Summary:
DF type pump can transport temperature is 20 ~ 105 ℃, - not containing solid particles, corrosive liquid. The pump inlet pressure is less than 0.6 MPa. DF type pump is horizontal, single suction and multi-stage sectional centrifugal pump, the pump's export entry are vertical, the pump suction segment, with tension bolt in the middle, spit out section connected into an organic whole, installed on the shaft of the impeller pump rotor, balance disc parts, etc. On both ends of the rotor is supported by rolling bearings or sliding bearing, roller bearing with grease lubrication, rotor axial force by the balancing disc.
Shaft seal adopts mechanical seal or packing seal, both sides have a sealed letter, built-in mechanical seal or soft packing, sealing letter zhongtong into a certain pressure of water, water seal and cooling effect. In the shaft seal is equipped with replaceable shaft sleeve, the protection of pump shaft, pump through flexible coupling driven directly by the original motor, from the original motor to pump, pump is clockwise.
