Precision Metal Sucker Rod Pump Description
The Sucker Rod Pumping System (SRP) is considered the most popular artificial lift method worldwide. Its applications cover very low downhole pressure wells, slim holes, multiple completions, high temperature and viscous oil. The SRP companies have improved the operation of the whole system including pump-off controllers, better gas separation, gas and solids handling pumps and optimization using surface and bottom-hole cards. Because its wide operation range and adaptability of the system to others wells with minimum cost becomes a economically attractive solution for oilfield development.
Puyang Zhongshi Group manufacture all subsurface pumps covered by
API Spec 11AX, including all barrel and plunger materials and
surface finishes.This is why our sucker rod pumps can be furnished
with the components most suitable for your field of application and
pumping operations can easily be extended to corrosive
environments.
To achieve maximum performance,API subsurface pumps are machined
with extra small clearance between the plunger and the inside wall
of the barrel.
