Moyno® 2000 K Drive End Parts
OEM-compatible replacement parts for K Drive End assemblies supporting K115, K175, K335, K345, K620, K800.
OEM part numbers are the primary identifiers. ACCA part numbers use the same part number with an A- prefix.
K Drive End Engineering Overview
This page follows the historical catalog organization for the K 2000 G1 Drive End, kits, shaft-sleeve options, fiber-deflector options, stators and rotors.
The engineering focus for this family includes the largest 2000 Series assemblies, planned outages and heavy-duty operation. Confirm the complete model, stages, trim, joint configuration and sealing arrangement before ordering.
Supported K Drive End Models
To help identify the correct K Drive End replacement parts, have the complete pump model, serial number, trim code, Drive End designation, OEM part number when known, and photographs of the assembly available.
K Drive End Parts Reference
The source lists OEM part numbers and descriptions without exploded-view item numbers. The Item column therefore shows a dash.

Maintenance Recommendations for K Drive End Assemblies
Plan the Overhaul Before Disassembly
K115, K175, K335, K345, K620 and K800 assemblies are large components. Identify required parts and lifting or handling requirements before the outage.
Inspect Maximum-Torque Components
Closely examine the gear ball, ring gear, joint shell, thrust plates, connecting rod and drive-shaft head for impact wear, pitting or deformation.
Evaluate Bearings and Housing
Inspect the roller bearing, spacer, lock nut, cover plate, seals and bearing housing for evidence of load, contamination or lubrication issues.
Check Shaft and Sealing Surfaces
Inspect shaft and sleeve surfaces, packing areas, lip seals and gland components before installing new sealing parts.
Confirm Large Rotor/Stator Configuration
Verify model, stages, rotor material and surface condition, stator elastomer and dimensional condition before replacement.
Use a Planned Rebuild Scope
On major K Drive End maintenance, inspect mating and wear components as an assembly rather than replacing only the first visibly damaged item.
Frequently Asked Questions
Which pump models use the K Drive End assembly?
This page covers replacement parts for pumps using the K Drive End assembly, including the K115, K175, K335, K345, K620, and K800 model families. Always verify the complete pump model, trim code and serial number before ordering replacement components.
How do I determine whether my pump uses a K Drive End?
The Drive End designation is part of the complete model number shown on the pump nameplate. Confirm the model designation, stage configuration, trim code and serial number to identify the correct Drive End assembly and replacement parts.
Can I replace only the worn components of the Drive End?
Many Drive End components—including bearings, gear-joint components, retaining rings, shafts, connecting rods, seals, packing and related hardware—can be replaced individually. During major maintenance, inspect mating components so wear in adjacent parts is not overlooked.
What information should I provide when requesting replacement parts?
Provide the complete pump model, serial number, trim code, OEM part number when available, quantity and photographs of the assembly. Operating conditions can also help confirm materials and configuration.
What are the most commonly replaced Drive End components?
Common replacement items include bearings, gear-joint components, drive shafts, connecting rods, retaining rings, lip seals, packing, O-rings and shaft-sealing components. Service life depends on the pumped fluid, operating conditions and maintenance practices.
