This page is an exact-model replacement-parts reference for the Moyno® 2000 Series 3K345 progressive cavity pump. ACCA Pumps supplies compatible replacement pumping elements for this configuration. Use the complete pump model and existing component part number to confirm the required replacement before ordering.
Verified Moyno 3K345 Replacement Part Numbers
| Component | Verified reference part number | Verified description |
|---|---|---|
| Stator | C3345Q | 3-stage 345 stator, RM100, carbon-steel tube |
| Rotor | C73341 | 3K345 rotor, alloy steel |
The verified ACCA cross-reference identifies C3345Q for the 3-stage 345 stator and C73341 for the 3K345 alloy-steel rotor. These references should be matched against the complete installed pump designation and service requirements rather than selected from the “345” displacement designation alone.
Verified 3K345 Pump Configuration
The ACCA cross-reference includes the complete pump model 3K345G1CDQ3AAA. In the Moyno 2000 model designation, the leading 3 identifies a three-stage pumping element, K identifies the K-size drive end, and 345 is the displacement designation. The G joint-style code identifies a gear-joint configuration.
For help reading the remaining construction and material codes on an installed pump, use the Moyno 2000 pump nameplate and model-code guide.
Confirm the Stator Material Before Ordering
The verified C3345Q reference is specifically identified as an RM100 stator. Do not assume that a different elastomer or construction is interchangeable solely because it is used with another 345-size pump. Fluid chemistry, temperature, abrasion and the complete pump construction must be considered when confirming a replacement.
See the progressive cavity pump stator elastomer guide for selection considerations, or use the Moyno replacement stator selection guide when the installed elastomer is uncertain.
3K345 Rotor Identification
The verified rotor reference for the 3K345 configuration is C73341, described in the ACCA cross-reference as a 3K345 alloy-steel rotor. Rotor material, size condition and the mating stator specification should be confirmed together when rebuilding the pumping element.
K-Size Drive-End Parts
Because 3K345 uses the K-size drive-end designation, related drive-end and service components should be identified through the Moyno 2000 K drive-end parts page. Do not infer a gear-joint kit, bearing kit or seal-kit part number from the 3K345 element designation alone; confirm those components from the complete model and existing part numbers.
How to Confirm a 3K345 Replacement
- Record the complete pump model from the nameplate.
- Confirm that the pumping element is the 3K345 configuration.
- Record the existing stator and rotor part numbers when available.
- Confirm the process fluid, temperature and solids or abrasion conditions before changing stator material.
- Check rotor condition and size when replacing a worn stator.
- For other verified numbers, use the Moyno pump parts cross-reference.
