Steam flooding large pump

The pump applies large diameter, long stroke pump barrel and plunger, effectively improve the liquid production capacity; Adopt the special on-off connector for large pump to complete the on-off operation between plunger pump and rod string; The upper outlet valve and lower plunger processed with acute sand scraping blade to removing the scaling and sand of the inner wall of pump barrel in the process of plunger reciprocating motion, thus reducing and avoiding the pump sand stuck.

This series of pump is suitable for high temperature, sand and other special heavy oil well and super heavy oil, and successfully solves the problems of the exploitation for super heavy oil.
