DF25-80X6 stainless steel multi-stage centrifugal pump complete set scope:

DF type stainless steel pump can be supplied with motor and base, and can be equipped with a common base or its own base. The manufacturer can also provide accessories (including discharge cone tube, gate valve, check valve) and spare parts (including impeller, sealing ring, guide vane sleeve, balance disc, shaft sleeve).

DF25-80X6 stainless steel multi-stage centrifugal pump structural type

The DF stainless steel pump is a single suction, multi-stage, and segmental multi-stage centrifugal pump. This pump type is horizontally installed, centrally supported, with horizontal suction and vertical discharge. Shaft seals generally use packing seals, and mechanical seals or other seals can also be used according to user needs. The bearings are lubricated with grease. The axial force of the pump is balanced by a balance plate mechanism.

Operation precautions for DF25-80X6 stainless steel multi-stage centrifugal pump

1. Starting conditions for DF25-80X6 stainless steel multi-stage centrifugal pump

a、 Stainless steel is only allowed to operate within the specified parameter range;

b、 Stainless steel pumps are not allowed to operate with the discharge valve closed or closed to a very small opening. Otherwise, it will cause the pump to heat up and reduce its lifespan. If the pump is installed in a parallel system, each pump must operate under specific parameters to ensure the flow rate of the pump;

c、 stainless steelMulti-stage pumpCannot close the suction valve for operation. Otherwise, it will cause the pump to run dry, resulting in damage to the pump components;

d、 The medium conveyed by the pump cannot contain air or gas, otherwise it will make it impossible to accurately measure the flow rate and head of the pump, and it will also cause grinding and damage to the parts.

2. Inspection before starting DF25-80X6 stainless steel multi-stage centrifugal pump

A、 Before starting the pump, the rotor should be turned to check if it is flexible;

B、 Check whether all bolts and pipeline leads are securely connected and the safety situation around the pump;

C、 Check if all instruments, valves, and devices are functioning properly

D、 Check whether the position of the oil ring and the oil level of the oil level gauge are normal;

e、 Check if the direction of the electric motor is consistent with the direction of the pump.
