Shengji API 11AX 20-150-RWAC-12-4-0 sucker rod pump for oil drilling
Shengji API 11AX 20-150-RWAC-12-4-0 sucker rod pump for oil drilling
Product DescriptionShengji 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, and it is convenient to check the pump and save time. The pump bore reaches 120.65mm, the max stoke length could be 9.2m and daily fluid production is approximately 151~452m3.
Shengji has 40 years’ experience in designing and manufacturing subsurface tubing pump and participated in the draw up of the national standard of subsurface tubing pump. Shengji also developed the unconventional pump suitable for heavy oil well , high gas-cut well and high sand-cut well. Shengji deep well pump has been exported to SHELL, CHEVRON, SCHLUMBERGER, GE, NOV, JOHNCRANE, CAMERON, KBM, etc. Annual production reaches 15,000 sets.
1.This pump has a steady performance and high pump efficiency.
2.Not influenced by tubing string, has a long service life.
3.Suitable for the high temperature and deep well.
4.Possess a good press-bearing and structure-gap bridge structure.
