L3 Drive End Engineering Overview

The L3 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.

Need help selecting an elastomer?

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.

L3 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 L3 page?

The primary frames are 1L3, 2L3, 3L3. Related configurations documented for the same drive-end family include 3M2, 6M2, 3P1, 6P1.

How do I identify the correct L3 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.

Does ACCA supply complete replacement pumps?

Yes. ACCA can support individual replacement parts, repair components and complete OEM-compatible pump assemblies for supported configurations.
