Technical specification
Supplied brand: Vidishi Auto — not GRH-branded; the original maker is referenced for fitment cross-checks only.
Each pump is inspected against the original equipment drawing before packing. The cast ironandaluminum body resists wear under continuous duty and holds tolerance through thermal cycling. The electrical rating is validated across the temperature range. Pressure class reaches 25 on the test bench. Flow capacity is 2000/. Dimensions are andmerchant. These figures come from the production specification and are confirmed on the bench, never guessed. Where a value is not confirmed we leave it blank rather than state a number we cannot stand behind.
The pump is supplied with the connector and sealing items shown in the gallery, so the installer has everything needed for a clean fit. Torque and clearance follow the original equipment spec.
The Dimensions (L×W×H) of andmerchant matters because it decides the space the unit needs in the panel or engine bay.
The Max flow rate of 2000/ matters because it sets the throughput the unit can sustain.
The Power (W) of 15kW matters because it sets the electrical load drawn in operation.
The Pressure of 25 matters because it sets the working envelope of the circuit.
The Weight of 10 matters because it matters for shipping and for hand-fitting in tight bays.
The Material of Cast ironandAluminum matters because it decides wear life and resistance to the medium.
The Type of pump matters because it is part of the specification we confirm before dispatch.
Every unit passes a pre-dispatch check before it is packed: response at the rated condition, a pressure or flow confirmation where the specification requires it, and a visual inspection of the seal and connector. A unit either passes and gets stamped or it is pulled from the batch. Shipping untested stock saves nothing when the unit comes back.

Fitment
Fitment verification
Confirm the engine code plate and the part number grh-148308 before purchase. This pump fits the applications in our fitment list. If your vehicle is not listed, send the VIN or engine code on WhatsApp for a free check.
The fastest fitment check is visual: same stamping, same connector, same bolt pattern. If any of the three disagrees, stop and send us a photo — forcing a wrong revision in damages more than the part itself.

| Verification channel | Send the VIN or a photo of the old part on WhatsApp — written confirmation before you pay. |
Typical replacement scenarios
Direct replacement
The old pump has failed and the vehicle is down. Match grh-148308 to the old stamping and fit the same reference — the fastest path back to service.
Preventive swap
During an adjacent repair, replace the pump while the access is already open. Cheaper than a second teardown later.
Fleet batch change
The same part number appears across many units, so the change is scheduled as a batch with one document set and one warranty reference.
In every scenario the first step is identical — confirm grh-148308 against the old stamping before the wrench moves.
We would rather say “unverified” than guess. If your application is not listed, send the engine code or the old stamping and we confirm fitment first — the answer arrives before the order does.

Symptoms & engineering notes
Engineering notes
The Single Double High Pressure Transmission Oil Change Gear Pump Excavator Part Hydraulic Gear Pump Pressure Max 200 Bar is designed around the original equipment geometry so the pump seats without modification. The cast ironandaluminum element keeps tolerance under thermal cycling and vibration. Actuation stays consistent across the rated temperature range. The pressure path is validated to 25 on the test bench. Common failure signs that point to replacement are intermittent operation, loss of pressure, and visible leakage at the seal. Replace on a clean bench and torque to the OE spec. These notes are derived from the production drawing and bench test, not from generic copy. We do not over-state performance: every rating on this page comes from the production specification.
A worn pump typically shows rising resistance, erratic response, or contamination at the seat. Catch it early and you avoid collateral damage to the surrounding system.
Replace the pump when you see any of these: the function works only after a tap; the reading drifts with temperature; or the surrounding housing shows heat discolouration from a poor seat. Catching it early protects the more expensive parts downstream. After fitting, a five-minute functional test saves a comeback.
Our rule is simple: publish what the bench proved, leave the rest blank. Inflated ratings sell once; honest ones keep the reorder coming.
Store the new pump in its sealed bag until fitment; dust and shop moisture on the seat or contacts are the avoidable causes of early failure. Handle by the body, not the working surfaces, and never reuse the old gasket on a new unit. A clean, dry fit is most of the battle for a long service life.

Connector condition is the first thing to check on removal.
Repeat failures usually point to a wiring or heat issue nearby.
Installation
- Disconnect power and relieve system pressure.
- Remove the old pump after noting the part number grh-148308.
- Clean the seat and check for debris or worn seals.
- Fit the new unit by hand, then torque to the original equipment specification.
- Restore power, pressurise slowly, and inspect for leaks.
- Run a functional test before returning the vehicle to service.
Installation difficulty is moderate. If unsure, use a qualified technician. Keep the old part until you confirm the new unit behaves correctly.
Set up before you start: torque wrench, clean bench, and the old unit beside the new one. Most comebacks trace back to a dirty seat or a guessed torque value. If the old part shows heat damage or contamination, find that root cause first — a new pump in the same conditions fails the same way.

Transmission & gearbox details
For transmission and gearbox products, confirm the reduction ratio, the input and output speed, and the torque rating against the drawing before fitting. This unit is rated 25 on the pressure side. The cast ironandaluminum housing keeps alignment under load. A worn gear set shows up as noise, backlash, or heat long before it fails outright.
- Confirm the reduction ratio and direction of rotation.
- Match the input flange and shaft diameter.
- Verify the output torque rating covers the driven load.
- Check the mounting face and bolt pattern.
Ratio and torque are the two numbers that decide whether a gearbox suits the machine. A unit specified for continuous duty will run cooler and quieter than one sized at the limit, and the service factor on the nameplate tells you which one you are buying. When you read a datasheet, the input speed, output speed, and rated torque are what the engineer actually checks.

Use the oil grade and fill volume marked on the unit. Running a gearbox low on oil is the fastest way to destroy the bearings and the tooth flanks. Check the seals at every service; a weeping seal lets dust in and oil out. Replace the breather if it is blocked, or pressure will push oil past the seals.
Oil does three jobs in a gearbox: it separates the teeth, it carries heat away, and it flushes wear particles to the filter or the sump. Viscosity is chosen for the ambient range on the nameplate, not for the average day, and synthetic grades hold their film strength longer under cold starts. Magnetic drain plugs are cheap insurance for iron wear debris.
Trade counters consolidate orders for transmission pump range with the specification sheet packed on top.
Distributors forecast demand for transmission pump range because a documented spec shortens receiving-line QC.
Rebuilders standardise on transmission pump range to keep the spare list short.
Sample approval for grh-148308 precedes bulk release, and the approved sample is the one the batch is judged against.
Reliability data for this pump on the applications in the fitment table comes from field returns, not from a brochure table. Batch 52115E4A.
Packaging updates are announced a full order cycle ahead.
Fitment & assembly checks
Set the unit on a clean face and check the coupling alignment with a dial indicator before final torque. Torque the mounting bolts in sequence to the specification for this pump. A soft foot or a misaligned coupling will destroy the input bearing within months.
After assembly, rotate the input by hand and feel for tight spots or roughness. Run a short no-load break-in, then check the case temperature and listen for noise at each bearing position. Document the alignment readings so the next swap follows the same record.
Wholesale partners quote volumes for hydraulic gear pump so the fitter works to torque values rather than habit.
Service centres specify hydraulic gear pump to cut diagnostic time on repeat failures.
Importers keep records for hydraulic gear pump because the batch record travels with the carton.
Applications for this pump include the applications in the fitment table — confirm the reference grh-148308 against the unit you remove.
The Cast ironandAluminum build is verified per production batch at China, Dongguan, with the batch code stamped on the housing. Batch 52115E4A.
Matching parts are quoted together so wear items ship as a set.
