Roper® 70328 Pump Parts
M10H oversized-drive pin-joint family
ACCA Pumps supplies independently manufactured aftermarket replacement parts for supported Roper® progressive cavity pump configurations. Use the complete pump figure, serial number and construction when identifying parts.
Roper® 70328 Engineering Overview
Roper® identifies the 70328 configuration in its oversized-drive pin-joint cross-reference. The Roper® parts book associates this M-designation family with the corresponding L10H pumping-element references for rotor and stator selection.
Oversized Drive End
The M configuration uses a larger drive-end arrangement while retaining model-specific progressive-cavity pumping elements.
Pin-Joint Service
Inspect pins, bushings, connecting-rod interfaces, retaining hardware and drive-end wear components together.
Complete Figure Required
Rotor, stator and drive-end construction can vary. Confirm the complete pump identification before ordering.

2-stage pumping-element reference used with the M10H family.
Roper® 70328 Rotor & Stator Part Numbers
Roper®’s cross-reference directs M-designation pumps to the corresponding L-family rotor and stator references. The table below shows the standard plated-steel rotor and Buna 70 steel-tube stator references; alternate materials and elastomers use different part numbers.
| Pumping Element | Rotor Part Number | Stator Part Number | Reference Construction |
|---|---|---|---|
| 71228 | D96-16 | D95-121 | Standard plated-steel rotor / Buna 70 steel-tube stator reference |
| 72228 | D96-17 | D95-125 | Standard plated-steel rotor / Buna 70 steel-tube stator reference |

These references are for technical identification. Always verify the complete Roper® figure, material construction, serial number and existing component before ordering. ACCA does not reproduce Roper® list pricing on these pages.
Roper® 70328 Maintenance Recommendations
Inspect Joint Wear
Check pins, bushings and mating bores as a system.
Verify Drive-End Configuration
Do not substitute a standard-drive component where the oversized M drive end requires a different part.
Confirm Pumping Element
Match rotor and stator to the complete stage-specific pumping-element reference.
Progressive Cavity Engineering Note — Drive-End Loading
Progressive cavity pumps transmit hydraulic and rotor/stator loads through the connecting rod and drive end. An oversized drive-end configuration can provide additional mechanical capacity while retaining the pumping-element geometry appropriate to the service.
Frequently Asked Questions
What does Roper® 70328 correspond to?
The Roper® parts cross-reference identifies 70328 with the M10H oversized-drive family and directs rotor/stator selection to the related L10H pumping-element references.
Are the drive-end and pumping-element part numbers the same as the 70200 model?
No. Rotor and stator references can be shared through the documented cross-reference, while the oversized-drive configuration can require different drive-end components.
What information should I send for a quote?
Send the complete pump figure, serial number, existing part number, quantity, construction and photographs when available.
Can ACCA supply individual service components?
Yes. ACCA can support individual replacement components for applicable configurations after the installed pump is identified.
