Oversized Drive End
M-designation models use an enlarged drive-end arrangement relative to the related standard-drive family.
Documented Pumping-Element Cross-Reference
Roper® directs M-designation rotor and stator selection to the corresponding L-family pumping-element cross-reference.
Model-Specific Service Parts
Drive-end adapters, pins, bushings and other components must be identified from the complete Roper® configuration.
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 is the Roper® 70300 Series?
It is the Roper® M-designation oversized-drive pin-joint family represented in the current Roper® progressive-cavity parts cross-reference.
Can I select parts using only the last digits of the model?
No. Use the complete Roper® figure, serial number and construction because drive-end and pumping-element configurations can differ.
Does ACCA publish Roper® list prices?
No. These ACCA pages are intended for technical identification and RFQ support rather than reproducing manufacturer price lists.
