Stainless steel sewage pump is actually sewage pump adopts the stainless steel. Want to choose the appropriate sewage pump, the first thing we should know the kinds of sewage pump.
Sewage pump types generally have a diving sewage pump, submerged sewage pump, self-priming sewage pump, sewage pump pipeline, the centrifugal sewage pump, etc.
Submerged sewage pump is mainly, YW submerged sewage pump, if using stainless steel material, becomes, stainless steel sewage pump.
Diving sewage pump is mainly, WQ,'ve diving sewage pump, if using stainless steel material, becomes, WQP or, QWP models. Some manufacturers also use the QWF to used for stainless steel sewage pump models. F represents the corrosion resistance.
Self-priming sewage pump is mainly, ZW, ZX, ZWL these three kinds of sewage pump. If using stainless steel material, is respectively, ZWP, ZXP, ZWLP stainless steel self-priming sewage pump.
Pipe sewage pump is mainly, GW vertical pipe drainage pump. Adopt stainless steel material, models for the GWP stainless steel sewage pump.
The centrifugal sewage pump is mainly, horizontal single stage centrifugal pump, PW sewage pump. Because the stainless steel material, models for the PWP or PWF. F the same corrosion resistance.
General sewage pump, if it is to pump body corrosion resistance requirement is not high, the use of cast iron. If corrosive is very strong, such as industrial wastewater, sewage and sewage drainage, or use stainless steel materials such as septic tank longer service life.
Involves specific selection again, you can refer to the following information:
1. The master site condition are consistent with those conditions of use (voltage, frequency, water and power supply capacity, etc.).
2. Select the pump specifications
1) preliminary selection of traffic: according to the demand to determine the pump flow.
2) identification of piping: according to the transmission medium to calculate the critical settling velocity, reasonable choose pipe diameter.
3) line loss calculation: according to the pipe length and bent pipe, valves, line loss calculation.
= 4) pump head calculation: water pump head of the water outlet to the vertical elevation difference + + + safety margin outlet pressure line loss (10%).
5) according to flow head to determine the pump model
6) determine installation: fixed and mobile.
3. Make sure the material of stainless steel sewage pump
According to the stainless steel material, there are three points, 304, 316 and 316 l. General medium PH between 4 ~ 10 304 material can be used. PH2 ~ 12 by 316. More than the two range, it is recommended to use 316 l.
