API 11AX down Hole Insert RHA Sucker Rod Pump Oilfield Pumping Equipment for Deep Oil WellsAPI 11AX Oilfield Sucker Rod Pump Price 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).     Technology   Model Nominal Dia. mm(in) Plunger Length m(ft) Stroke m Pump Constant m3/d In Sucker Rod 20-125TH 32(1.25) 1.2-1.8 (4-6) 0.6-7.3 1.14 ¾ 25-125TH 32(1.25) 0.6-7.3 1.14 ¾ 20-150TH 38(1.50) 0.6-7.3 1.64 ¾ 25-150TH 38(1.50) 0.6-7.3 1.64 ¾ 20-175TH 44(1.75) 0.6-7.3 2.24 ¾ 25-175TH 44(1.75) 0.6-7.3 2.24 ¾ 25-225TH 57(2.25) 0.6-7.3 3.69 ¾ 30-275TH 70(2.75) 0.6-7.3 5.50 ? 35-325TH 83(3.25) 0.6-7.3 7.70 ? 40-375TH 95(3.75) 0.6-7.3 10.26 1   Production Flow Detailed Images   Main parts process and material: Pump barrel: plain carbon steel plating (A1), ordinary carbon steel carbonitriding (B1), ordinary carbon steel carburizing (B2), low alloy steel nitride (B5).
