We can manufacture various non-standard pumps according to different customer requirements. Now the company provides 413(diameter105),425 (diameter108),475(diameter120),and 531(diameter135)large bore pumps. Among of them, Shengji specifically designed and manufactured 120 model anti-corrosion pump for Shell Company. This pump uses a spray metal plunger and the fitting uses special material. It takes heat treatment and has a good anti-corrosion property. The travelling valve cage of the pump features a hard liner, improved abrasion performance, tungsten carbide ball and seat also has high anti-corrosion performance. The standing valve is fishable, it is convenient to check the pump and save on time. The pump bore reaches 120.65mm, the max stoke length could is 9.2m and daily fluid production is approximately 151~452m3.
1.Rod pump can be pulled out from the well directly.
2.Well inspection and workover is convenient.
3.Reduce the cost of pumping test.
4.Suitable for deeper well.
