Q2 ALS RHB API insert pumps are heavy-walled, stationary barrel bottom hold-down pumps recognized by API as a standard design. These pumps are suitable for greater depths. The heavy-walled barrel is designed to better handle downhole pressures due to the extra wall thickness of barrel. Wall thickness on this design is 3/16. The bottom hold down design allows the ability to set pump at great depths due to the equalization of pressure between barrel OD and tubing ID therefore eliminating “breathing” of barrel when it is exposed to the reservoir pressures.
