Roper® 70600 Series Pump Parts
Twice-oversized pin-joint progressive cavity pump parts
The Roper® 70600 family uses a drive end two sizes larger than the standard 70200 drive end while retaining a standard 70200 pumping element. ACCA Pumps supports aftermarket replacement components and technical identification for applicable 70600 configurations.
Roper® 70600 Engineering Overview
Roper® identifies configuration digit 6 as a twice-oversized pin joint. The 70600 uses a drive end two sizes larger than the standard design with a standard 70200 pumping element, providing additional drive-end capacity for demanding pressure, viscosity and torque requirements.
Twice-Oversized Drive End
The drive-end configuration is two sizes larger than the corresponding standard 70200 arrangement.
Standard 70200 Element
Roper® states that the 70600 retains the standard 70200 pumping element while increasing drive-end capacity.
High-Demand Service
Roper® positions the 70300 and 70600 for high-pressure spraying, chemical injection into high-pressure lines and applications above 225 psi when properly selected.
How the Roper® 70600 Nomenclature Works
| Position | Meaning |
|---|---|
| 7 | Traditional rubber-lined Roper® progressive cavity pump series. |
| Second digit | Number of pumping-element stages. |
| 6 | Twice-oversized pin-joint drive configuration. |
| Final displacement digits | Approximate theoretical displacement in U.S. gallons per 100 revolutions; use only as an identification aid. |
Roper® 70600 Replacement Components
Rotors
Stage- and displacement-specific rotor constructions associated with the standard 70200 pumping element.
Stators
Documented Buna N, natural rubber, EPDM and fluoroelastomer constructions where applicable.
Drive Shafts
Oversized drive-shaft components must be identified from the complete 70600 figure and construction.
Connecting Rods & Pins
Connecting rods, pins, bushings and related pin-joint service hardware for supported configurations.
Bearings & Seals
Bearings, lip seals, packing and related service parts where documented for the applicable drive end.
Overhaul Hardware
Retainers, washers, spacers, keys, gland components and associated repair hardware.
70600 vs. 70300 Drive-End Configuration
| Roper® Family | Drive-End Arrangement | Pumping Element |
|---|---|---|
| 70300 | Next-larger drive end | Standard 70200 element |
| 70600 | Drive end two sizes larger | Standard 70200 element |
Before You Order Roper® 70600 Parts
Do not identify a 70600 pump from displacement alone
Provide the complete Roper® figure, specification, serial and type numbers whenever available. The pumping element may share references with a standard 70200 configuration, while the twice-oversized drive-end components can be different.
Progressive Cavity Engineering Note — Torque Capacity
PCP drive components carry both operating and starting loads. Higher viscosity, rotor/stator interference and differential pressure can increase torque demand, making drive-end sizing an important part of pump reliability.
Frequently Asked Questions
What does the 6 mean in Roper® 70600?
Roper®’s current nomenclature identifies configuration digit 6 as the twice-oversized pin-joint configuration.
Does the 70600 use a different pumping element from the 70200?
Roper® states that the 70600 uses a standard 70200 pumping element with a drive end two sizes larger.
Is the 70600 the same as the 70300?
No. Both use oversized drive ends, but the 70300 uses the next-larger drive end while the 70600 uses a drive end two sizes larger.
Can I order using only a rotor or stator number?
For pumping-element components that may be possible after verification, but drive-end service parts should be identified from the complete pump figure and serial information.
