Conventional PC Elastomer Line Nomenclature
The Model Number consists of a five-digit number followed by a three or four letter material code.
- The first character (7) indicates the Xeric progressing cavity pump series.
The second character (3) indicates the number of stages of pumping elements.
The third character (2) indicates the configuration.
- 2 = Standard Pin Joint
- 3 = Oversided Pin Joint
- 4 = Gear Joint
- 5 = Solid Drive Shaft Pin Joint
- 6 = Twice Oversized Pin Joint
The fourth, fifth, and (where appropriate) sixth digits (12) indicate the approximate theoretical displacement in U.S. gallons per 100 revolutions.
4th, 5th, 6th digits | 006 | 025 | 01 | 02 | 05 | 12 | 19 | 22 | 28 | 36 | 44 | 65 | 115 |
Gal./100 Rev. | .06 | .25 | 1 | 2 | 5 | 12 | 19 | 22 | 28 | 36 | 44 | 65 | 115 |
The three letters (GHM) indicate the materials of construction. The first letter (G) indicates the pump body. The second letter (H) indicates the internals. The third letter (M) indicates the stator elastomer.

NOTE: The preceding description of the figure number is to assist in identifying your Roper progressing cavity pump only. DO NOT attempt to derive any ratings or performance from the figure number. DO NOT use the explanation of the figure number to construct your own pump. Not all combinations are possible. For assistance in pump selection, it is recommended that you consult Roper Pump Company or an authorized distributor.
Occasionally, special pumps or configurations are required which are unique for a particular application. These modifications are clarified by a SPECification number. Identification of any items different than a standard pump can be made by consulting Roper Pump Company or an authorized distributor.
The SERIAL number is a unique number assigned to each pump built by Roper Pump Company.
In any communication concerning this pump, always be sure to include the Figure, Spec, Serial, and Type numbers so proper identification of the pump can be assured.
Rebuild Kits
Major rebuild kits available for standard pumps. See distributor or manufacturer for more details.

All our Progressive Cavity Pumps are backed by Roper Pumps’ expert technical support and customer service dedicated to getting the right pump at an economical price for every application.
Ideal for handling a wide variety of materials which are often considered unpumpable, the 70200 offers a practical solution for tough pumping problems like highly viscous, abrasive, shear sensitive, or solid containing materials.
The pin joint design has few wearing parts creating long, trouble-free performance. If service is necessary, you can count on simple, low-cost repairs; saving you money and time. Available in a full range of sizes from one-, two-, or three-stage designs the 70200 offers simple options to suit a wide variety of applications.
Sometimes you need a pump that can handle higher pressures, viscosities and torque. Applications like these require the 70300 or 70600 models which feature oversized drive ends.
For the 70300 the next larger drive end design is used with a standard 70200 element. The 70600 is customized with a drive end that is 2 times larger with a standard 70200 element. As a result, either model can handle high-pressure spraying, chemical injection into high-pressure lines and applications involving pressures above 225 psi.
The 70300 series also allows you to use the standard design, normally rated to 75 psi and 600 RPM, in applications which call for their full element ratings. Standard pumps offered in the 70300 series are three, four, and six-stage pumps.
In the most demanding jobs where the torque, viscosity, pressures and abrasion resistance are exponentially high our gear joint style 70400 series is the perfect fit.
The 70400 series pump is designed and built for applications where joint life is critical. The crowned gear joint design is sealed from the liquid; providing a drive system with a greater wear area and lower stresses making it the superior design in joint technology.
Its construction makes this gear joint pump ideal for applications where a longer maintenance interval is desired, accessibility to the pump is limited or where downtime must be kept to a minimum. Also, because the 70400 series gear joint pump comes standard with large clean-out ports, large objects can be removed from the suction housing without dismantling the pump.
Its solid drive shaft makes the 70500 the ideal choice for handling liquids with a tendency to set up — and eventually build up — in a hollow-shaft model.
That includes thermosetting adhesives, concrete, grout, plaster and other materials which have the potential to harden inside the shaft. When these materials are allowed to build up and harden, they inhibit free movement of the connecting rod, resulting in connecting rod breakage. In designing the 70500, Roper Pump Company engineers moved the pin joint connection from the middle of the drive shaft out to the end. This modification moved the connecting rod within the suction housing where material can be easily flushed.
