ENERJOINT MACHINERY

HYDRAULIC PUMPS
& PARTS

Right Parts. Reliable Supply.

Complete pump assemblies and internal repair parts for excavators and other construction machinery.

From complete pumps to the parts inside.

Enerjoint supplies replacement hydraulic pumps, rotating groups and individual repair components. Our range includes pistons and shoes, cylinder blocks, valve plates, swash plate assemblies, drive shafts and bearings. Parts can be quoted individually or as coordinated repair sets, according to the pump design and repair scope.

Our selection focuses on controlled internal leakage, wear resistance and consistent displacement control, helping reduce avoidable repeat repairs and downtime.

Details that support reliable pump performance

Useful flow as the oil warms

Controlled piston-to-bore fits and lapped cylinder-block/valve-plate faces help limit internal leakage, supporting useful flow as operating temperature rises.

Wear resistance at loaded surfaces

Surface hardness, finish and slipper-joint clearance must suit the design to support lubrication and resist scuffing at loaded sliding interfaces.

Predictable response to changing loads

The regulator design, servo-piston fit and displacement-control settings must match the application to support consistent pump response as working loads change.

Clean internals for a reliable start

Component washing, deburring and protected oil passages help keep damaging particles away from precision fits, reducing contamination-related scoring and early wear.

Repair components, individually or together

Rotating groups

Cylinder blocks, pistons and related rotating components for rebuilding the pump’s working group.

Swash plate assemblies

Swash plate assemblies and related parts for the pump’s displacement mechanism.

Pistons & shoes

Replacement pistons and shoes selected for the corresponding bore, joint and running-surface geometry.

Cylinder blocks

Replacement cylinder blocks matched to the piston dimensions and valve-plate arrangement of the pump design.

Valve plates, drive shafts, bearings, seals and related service parts can be included in the same enquiry.

Keep useful flow. Reduce repeat repair costs.

A pump that loses useful flow as the oil warms can slow the whole machine. Selecting the right working clearances, running surfaces and controls helps address avoidable performance losses, repeat dismantling and downtime.

How we work

A clearer path to the right part.

You do not need a perfect parts list to start. Send what you have; we will identify what still needs checking.

Only a photo or a worn-out label?

Start with a photo of the old part, the machine model or a nameplate. We will tell you which details are still needed.

Similar parts. Different configurations.

We check the reference and key details before confirming a match. If something is uncertain, we say so.

Send your list from anywhere.

A photo of your parts list is enough to get started. Send it by WhatsApp or email, we’ll review the items, clarify the details and prepare your quotation.

Clear specifications, practical options and reliable communication, from first inquiry to delivery.
