Roper® Rotors & Stators to Fit Moyno Pumps
Centennial and 2000 Series replacement pumping elements
Roper®’s current progressive-cavity parts book publishes direct replacement cross-references for selected Moyno Centennial and 2000 Series stators. ACCA Pumps can help identify aftermarket rotor and stator options using the existing Moyno or Roper® part number.
Moyno Centennial & 2000 Series Cross-Reference
The table below uses direct Moyno-to-Roper® stator references published by Roper® in its 2026 progressive-cavity parts book. Prices have intentionally been omitted. Always verify the complete pump model, construction and elastomer before ordering.

Why Search by Existing Part Number?
Moyno Part Number
Customers maintaining older Centennial and 2000 Series equipment often have the original C-series stator number on purchasing records or previous quotations.
Roper® Cross-Reference
Roper®’s published D95 replacement number provides another technical identifier for sourcing the correct stator construction.
Elastomer Matters
The final letter of the Moyno reference can correspond to a different elastomer construction. Do not drop that suffix when requesting a replacement.
Replacement Rotor & Stator Identification
Send us either manufacturer’s part number
If you have a Moyno C-series number, a Roper® D95 number, the complete pump model, or photographs of the existing component, ACCA can use those identifiers to help determine the applicable replacement. Rotor material, plating, stator tube construction and elastomer should all be confirmed before final selection.
Common Stator Elastomers in the Published Cross-Reference
Buna / NBR
A commonly published general-purpose stator construction in Roper®’s Moyno replacement cross-reference.
EPDM
Published for multiple Centennial and 2000 Series replacement stator references.
Natural Rubber
Roper® also publishes Natural Rubber 50 alternatives for a number of the same pumping-element sizes.
Progressive Cavity Engineering Note — Rotor/Stator Matching
The rotor and stator operate as a matched pumping element. Elastomer condition, rotor surface, temperature, chemical compatibility and interference all affect sealing between cavities, slip, starting torque and volumetric efficiency.
Frequently Asked Questions
Does Roper® publish replacement stators for Moyno pumps?
Yes. Roper®’s 2026 progressive-cavity parts book contains a dedicated Moyno Centennial and 2000 Series stator cross-reference with Moyno and Roper® part numbers.
Are Centennial and Moyno 2000 Series parts identical?
Do not assume interchangeability from the family name alone. Use the published part-number cross-reference and the complete installed pump identification.
Why are there several stator numbers for what appears to be the same size?
Elastomer and construction differences change the part number. The complete suffix is important when identifying a replacement stator.
Are Roper® list prices reproduced on this page?
No. This ACCA resource is for technical identification and replacement-part RFQs rather than republishing manufacturer price lists.
