Excavator Hydraulic Pumps

Excavator Hydraulic Pumps – Hitachi, John Deere, Caterpillar

V.I. Equipment is a name you can depend on for excavator hydraulic pumps. We sell quality excavator parts at low prices in Canada, the USA and worldwide. VI Equipment can supply rebuilt excavator hydraulic pumps for Caterpillar, John Deere and Hitachi excavators. If you’re in need of a rebuilt Cat excavator hydraulic pump, Deere hydraulic pump or Hitachi hydraulic pump, please contact us today. Our excavator parts inventory includes all major components for most models of Caterpillar, John Deere, and Hitachi excavators. Furthermore, we have the ability to test your hydraulic pumps with our very own test stands (see photo) to ensure they work properly.

Pump Test Stand

These test stands can examine a variety of hydraulic components before shipping to ensure you’re receiving a quality product. We offer this service at no extra cost because we believe in giving our customers the best quality hydraulic pumps, whether they’re new, or rebuilt.

We Ship Excavator Hydraulic Pumps to the USA, Canada, and Worldwide

No matter where your project takes you, VI Equipment can keep you moving. We offer global shipping on all our excavator hydraulic pumps, ensuring you get the parts you need quickly and efficiently.

Why Shop VI Equipment for Your Excavator Hydraulic Pumps

There are many reasons to choose VI Equipment for your excavator hydraulic pumps. We offer exceptional value, unmatched selection, and reliable performance to keep your projects on track. Discover the VI Equipment difference and experience the benefits firsthand.

Excavator Hydraulic Pumps: The Power Source Behind Every Dig

A healthy hydraulic pump delivers the precise flow and pressure your excavator needs to swing, crowd, and lift on demand. When wear sets in—scoring on the barrel plate, leaking swash plates, or plungers losing tolerance—cycle times stretch and operators have to “feather” controls to compensate. VI Equipment stocks fully dressed main pumps, pilot pumps, and tandem units that bolt straight in and restore factory performance, fuel efficiency, and breakout force.

Reman & Brand-New Pumps for John Deere, Hitachi & Caterpillar

From a Deere 135G’s Kawasaki tandem pump to a Cat 336’s Rexroth variable-displacement unit, we catalogue pumps by machine model, serial prefix, and OEM reference so matching takes minutes. Our remanufactured pumps are stripped to bare casting, crack-checked, and rebuilt with new bearings, pistons, and valve plates—delivering OEM specs at about 60 % of dealer cost. Prefer brand-new? Our premium aftermarket line uses forged cases, nitrided swash plates, and high-density seals, all backed by a 12-month unlimited-hour warranty.

Diagnosing Pump Wear Before Productivity Drops

Watch for slow boom response, hydraulic oil temps creeping above 85 °C, or case-drain flow exceeding 10 % of rated output—classic signs of internal leakage. A simple flow meter test at rated RPM will confirm whether the pump is holding spec. Email us the case-drain rate or a photo of your pump tag and we’ll confirm whether a reseal kit, bench rebuild, or full replacement makes the most economic sense.

In-House Pump Rebuilds: Dyno-Tested for Flow & Pressure

Our Langley hydraulic lab turns most rebuilds in five business days. We lap valve plates to <2 µm, blueprint swash-plate angles, and balance rotating groups to ISO 1940 G2.5. Each pump runs on a 400 hp dyno where we log flow, pressure, case-drain, and noise at 25 %, 50 %, 75 %, and 100 % displacement. A printout of the curve ships in the crate so you know exactly what’s going back into your machine.

Core Exchange Program: Save Time and Cash

Send us your worn pump and grab a ready-to-install reman from our shelf the same day. We credit the core once it passes inspection—cutting your net cost and keeping cast iron out of the scrap pile. Ask our parts desk for current core values and shipping labels.

FAQ – Frequently Asked Questions

1. What is an excavator hydraulic pump?
   An excavator hydraulic pump converts mechanical power from the machine’s engine into hydraulic flow and pressure, which drives the boom, arm, bucket, tracks and other hydraulic functions.

2. How do I know if the hydraulic pump on my excavator needs replacement?
   Common signs include reduced speed or force in hydraulic operations, unusual noises from the pump, excessive heat or cavitation in the system, visible leaks at pump connections, and possibly contamination in the hydraulic fluid. When you observe slower arm/boom movement or weaker attachments, it could indicate pump wear or failure.

3. What types of hydraulic pumps are used on excavators?
   Excavators may employ gear pumps, vane pumps or piston pumps. Piston pumps are commonly used in heavy-duty excavator hydraulic systems because they handle higher pressure and provide better control.

4. How do I select the correct replacement excavator hydraulic pump?
   You’ll need to match the make and model of your machine (brand, series, serial number), the pump model/part number, displacement, pressure rating, mounting configuration, and shaft interface. Providing your machine’s full specification to the supplier will ensure compatibility.

5. Are used or remanufactured hydraulic pumps safe to use?
   Yes, when sourced from a trusted supplier who inspects and tests the unit, ensures correct match-up, and offers warranty or guarantee. Using a reliable used or re-manufactured pump can offer cost savings while maintaining performance.

6. What maintenance is required after installing a new hydraulic pump?
   After installation: ensure the hydraulic fluid is at the correct level and quality, bleed any air out of the system, check for leaks at pump seals and connections, verify that system pressure and flow are within spec, monitor for abnormal noise or vibration during the first hours of operation, and keep up regular maintenance (filter changes, fluid cleanliness, hose & fitting checks) to maximise pump life.

7. How much downtime can a failed hydraulic pump cause and how quickly can replacement happen?
   Downtime depends on machine size and job schedule. With a supplier of correct inventory, a replacement hydraulic pump (or same-model unit) can often be installed in hours rather than days, significantly reducing downtime versus a full machine replacement or waiting for new OEM parts.
