Valve PU seal is worked for oil drilling mud pump and cementing piston. It’s usage is sealing and buffer. It is made of polyurethane material, which have the super advantage of oil resistant, corrosion resistance, abrasion resistance. And wild work temperature of -35℃-100℃, work pressure of 40MPa. Polyurethane have long lifetime than rubber, it’s wildly used for the consumables of oilfield fracturing cars, oilfield washing cars, cementing cement truck cement truck, piston pumps, mud pumps and other oil equipment.

Tailored sizes as request of customer

Many color can be available .

Polyurethane Characteristics

1. Long service time. Its service life is more than 8 times longer than the ordinary metal products and 3.9 times longer than the rubber products.

2. Large bear capacity. With good resilence, high strength to absorb the impact, high wear resistance, high tensile strength,so its capacity is more than 2.5 times stronger than the rubber and stainless product.

3. High sieving efficiency. On the base of meeting the size distribution, the mesh slot is made into the shape of rectangle. Which gurantees the ratio of qualified fine material and improves the screening effciency.

4. No blocking by the hole.With the resilience nature, the aperture is prevented from blockage.

5. Low niose. Polyurethane sieve machine can reduce noise 5-20 decibels than metal mesh.

6. Low maintenance cost.Easy to installation, simple to replace, long service time ensure the low maintenance cost.

7. Large amount of ore sieving. Polyurethane screen mesh can sieving more than 200000 tons ores.

8. Abrasive resistant. Tear resistant and corrosive resistant.High Quality polyurethane screen mesh for Mining
