4~30KW Corrosion resistant pump / PWF stainless steel sewage pump
PW horizontal sewage pump Scope:
- PW horizontal sewage pump can transport sewage, containing
suspended solids, long fiber material and domestic wastewater. The
pump body is of high quality cast iron material, the medium
temperature does not exceed 100 ℃.
- PWF stainless steel sewage pump can be transported with acidic,
alkaline or other corrosive sewage, widely used in chemical,
petroleum, light industry, food, pharmaceutical, brewing,
environmental protection and sewage treatment industries. The pump
body and the overcurrent part are made of 304 stainless steel, the
medium temperature is not higher than 100 ℃.
PW type horizontal sewage pump start, stop and run:
- Check whether the bearing tank has been refueled, the oil level is
normal oil level line.
- Check that the direction of rotation of the motor is the same as
the direction of rotation of the pump.
- Close the outlet valve and pressure gauge cocks, while the upper
part of the pump screw hole, to the pump suction pipe irrigation.
- Start the motor and open the pressure gauge cock.
- to be the normal speed of the pump to work, the pressure gauge
shows the corresponding pressure, open the vacuum table cocks and
gradually open the drain line on the valve to the needs of so
- Slowly close the outlet pipe valve, and then cut off the power.
- In case of frozen season, after the shutdown, open the lower part
of the pump body of the four plugs, venting water, so as not to
- If the long term do not, then the parts should be opened to wipe,
and in the sliding surface coated with anti-rust oil, proper
- During the operation of the pump, we must pay attention to observe
the instrument, bearing heat, filler leakage and pump vibration,
noise, etc. are normal, such as abnormalities should be promptly
- bearing the maximum temperature shall not exceed 75 ℃.
- bearing oil should be maintained in the normal oil level line, not
too high or too low, too low should be timely refueling.
- seal ring and impeller with the gap, greater than the following
specified value should be replaced when the new seal ring.
When the diameter of the suction nozzle is less than or equal to
100mm, the total clearance in the diameter direction is ≥1.5mm
When the diameter of the suction port is> 100mm, the total
diameter of the diameter is ≥2mm
