How to choose the rubber material of the rotor of the sewage oil lifting pump

Guide: To make the oil lifting pump more efficient, one important thing is the choice of the rubber material of the rotor, there are many types of rubber materials on the market, including nitrile rubber, neoprene, natural rubber, etc., so how to choose?

1. Nitrile rubber

This material is very resistant to fuel oil and aromatic solvents, but it should be noted that it is not resistant to ketones.

2. Neoprene

The opposite of NBR, with good resistance to oil and solvents, but not to aromatic oils, this rubber has a long service life and is resistant to weathering and long-term use at temperatures above 200°C without any problems. It also has good corrosion resistance and flexural properties, and is widely used in the use of dirty oil lift pumps.

3. Natural rubber

Natural rubber has good overall performance, cold resistance, has a high elasticity, easy to rebound after use, but a bad place is not resistant to mineral oil, so special attention should be paid when using.

4、Fluoroelastomer

can work in 200 ~ 250 ℃ ambient high temperature, excellent oil resistance, mostly used in the manufacture of cylinder liner seals, has a good sealing and service life, can significantly improve the use of time.

5、Silicone rubber

Silicone rubber is often used in the rotor rubber material of dirty oil lifting pump, this rubber material is very resistant to high and low temperatures, ozone resistance, the normal working temperature range is -70 to 260 ℃, as long as it is within this working temperature, it is possible to have good elasticity, and also has good ozone resistance, weather resistance advantages.

How to choose the rubber material for the rotor of dirty oil lift pump, now you know it, then you may want to refer to it when you make the selection.
