Moyno® J-Frame Pumps & Replacement Parts
ACCA Pumps supplies private-label replacement pumps and aftermarket parts for Moyno J-Frame progressive cavity pump applications. J-Frame pumps use an open-throat inlet arrangement intended to help feed viscous, high-solids and semi-solid materials into the pumping elements.
Replacement requirements should be confirmed from the complete pump model, size, construction, stator/elastomer, rotor and joint configuration, operating conditions and the existing equipment being replaced. Moyno model names are used for identification and compatibility reference.
J-Frame Open-Throat Progressive Cavity Design
The J-Frame family is associated with a rectangular open-throat suction and an auger-style feed arrangement rather than the conventional round flanged suction used on many standard progressive cavity pumps. This configuration can help move difficult-to-feed materials toward the rotor and stator.
J-Frame equipment is commonly considered for viscous products, sludge, filter cake and other materials that may not feed consistently through a conventional suction connection. Some J-Frame configurations were also offered with bridge-breaking arrangements for materials prone to bridging above the auger.
Moyno J-Frame Models
Common J-Frame model references encountered by ACCA include:
| Model Reference | Pump Family | Inlet Style |
|---|---|---|
| 2J4 | J-Frame | Open throat |
| 3J4 | J-Frame | Open throat |
| 2J6 | J-Frame | Open throat |
| 3J6 | J-Frame | Open throat |
Model designation alone is not sufficient to establish component interchangeability. Confirm the complete configuration before ordering.
J-Frame Replacement Pumps & Parts
Depending on the specific configuration, ACCA can support complete replacement pumps and components such as rotors, stators, connecting components, shafts, suction housings, discharge components, seals, bearings and related service parts. Material and elastomer selection should be matched to the pumped product and operating conditions.
J-Frame vs. L-Frame
The J-Frame and L-Frame are related progressive cavity pump families, but their inlet and feed arrangements differ. J-Frame equipment uses an open-throat feed arrangement for difficult-to-feed materials, while the L-Frame uses a conventional suction connection. For standard L-Frame replacement parts, visit the Moyno L-Frame Parts hub.

Information to Send With Your RFQ
Send the pump model, serial number when available, required part or complete-pump requirement, rotor and stator information, elastomer, materials, service fluid or solids description, flow, pressure and operating speed. Photos of the nameplate and existing components can also help with identification.
