Moyno® L6 Pump Parts
OEM-compatible replacement parts for the L6 Drive End and supported 1L6, 2L6, 3L6 pump frames.
Use the complete frame size, type designation, serial number and trim code to select the correct drive-end components, rotor and stator.
L6 Drive End Engineering Overview
The L6 page is organized around the original L-Frame drive-end parts structure. Drive-end components are selected from the pump type designation, while rotor and stator references are selected by complete frame size. Related M- and P-frame configurations can share this drive end where the pumping element size has been adapted to a larger drive end.
Pin-Joint Drive Train
Inspect the drive shaft, pins, connecting rod and retaining hardware as a system during overhaul.
Model and Material Identification
The complete nameplate designation matters because materials of construction and sealing arrangements affect the applicable part number.
Rotor and Stator Selection
Confirm the complete frame and material configuration before matching rotor and stator references.

Advanced Elastomer Engineering for Progressive Cavity Pumps
Every application is different, and the standard elastomer may not always be the best choice.
In addition to OEM-equivalent elastomer compounds, ACCA Pumps can manufacture stators using specialized elastomers engineered for specific operating conditions. Application-specific material selection can help improve chemical compatibility, wear resistance, service life and overall progressive cavity pump performance.
Abrasive & Solids-Bearing Service
Material options can be evaluated for wastewater sludge, mining slurries and other abrasive process streams.
Chemical Compatibility
Stator compounds can be selected around acids, caustics, hydrocarbons, polymers and other challenging process fluids.
Temperature & Process Conditions
ACCA can review fluid temperature, operating pressure and process conditions when recommending an elastomer solution.
Contact ACCA Pumps with the process fluid, operating temperature, pressure and pump model. Our engineering team can recommend a stator material for the specific application.
L6 Maintenance Recommendations
Inspect Pin-Joint Wear
Inspect pins, bores, connecting-rod ends and retaining hardware together.
Review Bearings and Seals
Inspect bearing and sealing components whenever the drive end is opened for major service.
Verify Packing Arrangement
Record packing gland, packing, lantern-ring and washer arrangement before disassembly.
Confirm Rotor/Stator Match
Use the complete frame and material specification when replacing pumping elements.
Protect Stator Installation
Use compatible assembly lubricant and protect stator threads or interfaces during installation.
Avoid Dry Running
Prime the pump with compatible process fluid before startup and confirm an open discharge path.
Frequently Asked Questions
Which pump frames are covered by the L6 page?

How do I identify the correct L6 replacement part?
Use the complete frame size, type designation, serial number and trim code. Material and configuration differences can change the applicable part number.
Can I order individual pin-joint components?
Yes. Individual drive-train components are referenced where available, but all mating wear parts should be inspected during overhaul.
How should I select a rotor or stator?
Confirm the complete frame size and construction. Rotor and stator references are frame-specific and can vary by material or finish.
