Thin Walled Barrel RW Series Oil Downhole Pumps
RW series oil well downhole pump description:
If the sucker rod downhole pump appeared quality problem, need not put forward the tubing string, only need put the whole pump forward well through the sucker rod string together , operation is simple.
Long plunger and antisand sticking pump is improved based on the long plunger tubing pump by adding a sand setting tube and a joint, thus preventing the pump from being stuck by sand.
Long plunger and anti-sand sticking pump can be used in the wells of sand content about 0.8%, and consists of a barrel assembly, a plunger assembly and a sand control assembly.
The pump has long plunger and short barrel so that the plunger seals the barrel all the time.
Because of the special heat treatment towards the inside surface of the barrel, it is much better than the standard barrel in
anti-wear and anticorrosion capacity.
