Spray metal plunger downhole insert pump description:


API recognizes two main types of pumps: rod and tubing. Rod pumps also are called insert pumps because they are run (inserted) in the production tubing. Tubing pumps are so named because the working barrel of this pump is coupled with the production-tubing string.

Heavy wall and thin wall sucker rod pumps are equipped with a seating nipple(there are two seating nipples in API-RHBM-AC) , seating nipple connection on the tubing string, down to the bottom of the well with the tubing string. Plunger assembly connection on the sucker rod string and with the pump overall down to seating nipple position together , pump with fixed inside the seating nipple , Plunger assembly with the sucker rod string up and down reciprocating movement to achieve pumping work.
if the 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.

It is important to know that the users of API pumps need to provide, along with the pump nomenclature, the following ordering information: barrel and plunger material, plunger clearance (or fit tolerance), and valve (ball and seat) and fittings material.
