Rod Pumps,Tubing Pumps

　　Rod Pumps:
The rod pump 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).

　　Tubing Pumps:
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 THMtype 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.
