Long Plunger And Anti-sand Sticking Pump

 

• The pump is improved based on the long plunger tubing pump by adding a sand settling tube and a joint, thus preventing the pump from being stuck by sand. The pump can be used in the wells of sand  content about 0.8%. 
•   The pump consists of a barrel assembly, a plunger assembly and a sand control assembly. 
•   It 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.
