Brass Sucker Rod Pump
To solve downhole sucker rod pump corrosion, Sanjack developed a brass sucker rod pump using precise rolling after 2 years of studying. Now, Sanjack is the first manufacturer in China and the products have been successfully exported to America, Canada, Russia, Tunisia, Kazakhstan, Iran, etc.
2.ESP Housing, Motor Bearing and Housing
ESP housing and spline bearing made by Sanjack have high dimensional accuracy, which can be used directly without honing.
