Moyno® 332 Pump Parts
OEM-compatible replacement components and part-number cross-references for supported Moyno® 332 progressive cavity pumps.
ACCA Pumps organizes 332 rotors, stators, flexible joints, drive shafts, bearings, sealing components and service hardware using the OEM 500 Series service structure.
332 Engineering Overview
The 332 is part of the Moyno® 500 Series 300-model family. It uses a flexible joint to transmit torque between the drive shaft and rotor while accommodating eccentric rotor motion. The 332 uses stator ring 320-7812-000 during assembly, the same feature documented for the 331.
Flexible-Joint Drive
Inspect the shaft, flexible joint and rotor together during overhaul because wear in one component can affect adjacent drive-train parts.
Model Identification
Use the complete model suffix and serial number. Material and sealing variations can change the applicable OEM part number.
Rotor & Stator Selection
The 332 uses model-specific rotor and stator part numbers listed in the OEM service documentation.
