API Sucker Rod Pump with competitive price

1. Introduction:

Comparing with conventional tubing pump, The API Tubing Pump has better performance in corrosion resistance & antifriction aspects. Plunger of it is nickel plated on alloy base, inside wall of barrel is plated hard cadmium, key parts, such as valve hood, valve ball, are made of materials with excellent mechanical performance and corrosion resistant property. Compared with conventional pump, the series of pump has a longer working life.

3. Product Description:

The THD type of tubing pump means that its standing valve is directly connected to the barrel and it cannot be pulled up separately with the barrel. The THC or THM type of tubing pump means that its standing valve can be pulled up separately with the barrel. The seating assembly of THC pump is cup type and for THM is mechanical type. The THC and THM type of tubing pump are suitable for the frequently work-over wells.

The rod pump is connected to sucker rod after being assemblied on the surface then it is pulled down to the well bottom through the tubing. Thus it is convenient for the inspection and workover because they can be pulled up and down through the tubing and suitable for deeper well. The life span of tubing can be prolonged for decreasing the times of the thread of the tubing being turned on and off and the time of the workover. The rod pump can be classified into two types of mechanical seating and cup seating. Also it is divided into three types as RHA (stationary heavy well barrel top anchor rod pump), RHB (stationary heavy well barrel bottom anchor rod pump) and RHT (travelling heavy well barrel bottom anchor rod pump).
