What is the selection method of pneumatic diaphragm pump material?

Pneumatic diaphragm pump product flow is generally between 0-50 cubic meters/hour, head 0-70 meters. You need flow and head within this range, diaphragm pump can be used. So we know what is the selection method of pneumatic diaphragm pump material?

Pneumatic diaphragm pump material selection method is as follows:

Diaphragm pump according to the pump body material is divided into: cast steel diaphragm pump, aluminum alloy diaphragm pump, engineering plastic diaphragm pump, stainless steel diaphragm pump and fluorine plastic diaphragm pump

Stainless steel: wear resistance, corrosion resistance, organic solvent resistance, acid resistance slightly poor, slightly higher price; Stainless steel we are more familiar with, most of the material can be transported.

Fluorine plastic: commonly known as plastic king, can withstand various concentrations of strong acid and alkali, all the material can be used, the price is high.

Cast iron: wear-resistant, inexpensive and resistant to slight corrosion; Such as sewage, sludge, rainwater, wastewater treatment.

Aluminum alloy: lightweight, the same performance as cast iron, cheap, mild corrosion resistance; For example, paint, coating industry used more.

Engineering plastics: acid, alkali and corrosion resistant, cost-effective, not resistant to organic solvents. If the concentration is not high, all kinds of acid and base solvents.

We all in the pneumatic diaphragm pump material selection, we can according to the above selection method to choose our pneumatic diaphragm pump, choose our appropriate material is very important to us.
