Moyno L-Frame Parts Engineering Overview
The L-Frame is a long-established progressive cavity pump configuration built around a pin-joint drive train. The design uses a rotor pinned to a connecting rod and a drive shaft, with the joint components accessible in the suction-housing area. This construction is distinct from the gear-joint arrangement used in the Moyno 2000 Series.
Pin-Joint Drive Train
The L-Frame uses exposed pin joints to transmit torque through the connecting rod to the rotor. During overhaul, pins, joint bores, bushings, retaining hardware and mating surfaces should be inspected together.
Threaded Stator Configuration
Traditional L-Frame construction uses threaded stator arrangements. Pump model, element size, stages, stator construction and material specification should be confirmed before selecting a replacement.
Serviceable Rotating Assembly
The L-Frame layout allows maintenance personnel to service the rotor, stator, connecting rod and drive components as part of a planned pump overhaul while retaining the installed piping arrangement when appropriate.
The 2000 Series uses a gear-joint drive design, while the L-Frame uses a pin-joint drive design. If your pump is a 2000 Series model, browse the dedicated drive-end parts catalog.

Why Facilities Use ACCA L-Frame Replacement Parts
Model-Based Identification
Parts are selected around the complete L-Frame model, stage count, materials and sealing arrangement rather than appearance alone.
OEM Part Number Support
Existing OEM part numbers can be used to help identify the applicable ACCA replacement reference.
Material Review
Rotor, stator, joint and sealing materials can be reviewed around the actual process fluid and operating conditions.
Pin-Joint Expertise
Maintenance support considers the complete pin-joint drive train, including pins, connecting rods, drive shafts and associated wear surfaces.
Engineering Support
ACCA can assist with identification when only a model, nameplate, old part number or worn component is available.
Complete Pump Solutions
Support extends from individual replacement parts and kits to complete OEM-compatible L-Frame pump assemblies.
Industrial Applications for L-Frame Progressive Cavity Pumps
Wastewater Treatment
Sludge, polymers, chemicals and other viscous or solids-bearing process streams.
Chemical Processing
Metering and transfer duties where steady, low-pulsation displacement is important.
Food & Beverage
Viscous and shear-sensitive process fluids where progressive cavity pumping is appropriate.
Mining & Minerals
Slurries and abrasive process fluids requiring controlled positive-displacement transfer.
Oil & Gas
Viscous liquids, produced-fluid duties and industrial transfer applications.
Pulp & Paper
Stock, coatings, additives and other process fluids requiring steady transfer.
Maintenance Recommendations for L-Frame Pumps
Inspect the Pin Joints
Check pins, bores, bushings, retaining hardware and mating surfaces for wear, deformation or excessive clearance during scheduled maintenance.
Evaluate Rotor and Stator Together
Wear in either pumping element can increase slip and reduce pressure or capacity. Inspect the rotor surface and stator condition as a pair.
Review Bearings and Seals
Inspect bearings, grease seals, packing or mechanical-seal components whenever the drive end is opened for major service.
Check the Connecting Rod
Inspect the connecting rod and joint interfaces for alignment, wear and evidence of a previous torque or solids upset.
Confirm Stator Construction
Verify stator type, stages, elastomer or rigid material, and process compatibility before substitution.
Document Existing Parts
Record OEM part numbers, nameplate information, photographs and relevant dimensions before disassembly when possible.
Frequently Asked Questions
What is a Moyno L-Frame pump?
The L-Frame is a progressive cavity pump family that uses a pin-joint drive train between the drive shaft, connecting rod and rotor. The family has been produced in multiple element sizes, stage configurations and material combinations.
How do I identify my L-Frame model?
Start with the complete model number on the pump nameplate. For this catalog, supported element sizes are L2, L3, L4, L6, L8, L10, L10H, L12 and L12H. The stage count and drive-end configuration must also be confirmed.
Which L-Frame replacement parts are available?
Supported replacement categories include pin-joint components, rotors, stators, connecting rods, drive shafts, bearings, seals, packing components, repair kits and complete replacement pumps.
Can individual pin-joint components be replaced?
Many pin-joint components can be serviced individually. Inspect all mating joint components during overhaul because wear in one component can affect adjacent parts.
What information should I provide for an L-Frame parts quotation?
Provide the complete model, serial number, stage count, OEM part number when known, quantity, and photographs of the nameplate or component. Material and operating information can also help confirm the correct configuration.
Does ACCA supply complete L-Frame replacement pumps?
Yes. ACCA supplies complete OEM-compatible progressive cavity pump assemblies for supported L-Frame installations in addition to individual replacement components.
Use the Moyno Pump Parts Cross Reference to locate an OEM reference among more than 4,700 listed components, then confirm the complete model and serial number with ACCA.
