Product Advantage

The operating pressure of the hydraulic cylinder is stable and the system equipment has a long service life.

Small size, light quality, easy moved and installed, esp. suitable for shoal, offshore platform and mountainous area pumping operation.

Easy to achieve long stroke, low stroke, and stroke, stroke can be steplessly adjusted.

It has strong adaptability to large loads and can meet the needs of deep wells and heavy oil wells.

Realize remote transmission and automatic control of oil well data.

One control more wells, so it achieves to drive more wells on one platform.
