In order to increase the anti-corrosive property of tubing pump, Shengji designed anti-corrosive tubing pump. The conventional tubing pumps usually use carbon steel as the basic material in the high corrosion oil well. Such pumps easily get corroded and the service life is greatly reduced.

Compared with conventional tubing pump, anti-corrosive pump adopts a special technology and has a strong anti-corrosive property. In this pump, the barrel has an anti-corrosive treatment; the surface of the plunger coated with nickel alloy and the cage made of anti-corrosive material with good mechanical property.

This completely solves the corrosion and crack problems. The ball and seat have strong anti-corrosive and wear resistance properties. With these good properties, this pump can be used in the medium with high H2S, CO2 and salinity. It guarantees an extended service life and good performance.

1. Uses a special anti-corrosive material that has long service life.
2. Take anti-corrosive treatment.
3. Good wear resistance property.
4. Suitable for high salinity oil well.

Shengji developed a new cage lined anti-corrosive pump. Compared to other anti-corrosive pumps, this pump takes more treatment to the cage and it adds a hardliner in the valve chamber. The plunger upper cage and lower cage take the nickel-phosphor plate.

Although this increase the cost, but it guarantees good anti-corrosion and better mechanical performance. The standing valve cage uses a Teflon liner. This materials has a very good anti-corrosion property, wear resistance and heat resistance quality. It is superior to other companies’ liner material.

These material improves wear resistance of the cage, enhanced anti-corrosion property, and extend the cage life. The travelling ball material is tungsten carbide, it has improved hardness and impact resistance, the ball and seat have a perfect seal.

1. The pump has a hard liner which increase anti-corrosive property.
2. Use nickel-phosphor plate for plunger cage.
3. Long service life in the corrosion well.
4. It is suitable for the high salinity well.

For the high production and high H2S, CO2 oil wells, Shengji designed and manufactured an integral match anti-corrosive pump. In this pump, the barrel is made of stainless material and make chrome plated, the fitting is made of austenitic stainless steel, the ball and seating is a tungsten carbide which increases the pump anti-corrosive property.

This kind pump matches drainer device, puller device and pump as an integral unit. It has a strong anti-corrosive property. This pump solves the complement problems of the tools and fluid corrosion problems. So, it is suitable for the high production well, which has sufficient feed fluid and need large bore pump to increase oil production.

The super anti-corrosive pump has a good performance in the high H2S, CO2 oil well, extend the service lift and reduce the cost of oil production.

1. Super anti-corrosive property
2. Increase oil production in the corrosion well.
3. Uses drainer, puller and pump as an integral unit.
4. Solve the complement problems of tools.
