Not Every Tipper Needs a Piston Pump — Eaton's Gear Pump Makes the Case
The Sauer Danfoss PV22 is excellent — and so is a ₹40,000 piston pump when your tipper body is 18 cubic metres. But for a standard 10-14 cubic metre tipper running on a Tata LPT 1412 or smaller commercial vehicle, an Eaton gear pump does the same job at half the cost and is significantly simpler to refurbish. PumpGrid supplies tested refurbished Eaton tipper pumps for operators who understand the difference.
India's tipper fleet is diverse — from a 6-tyre Tata LPT 1412 carrying 8 cubic metres of sand on a rural site to a 10-tyre Bharat Benz 3143 hauling 18 cubic metres on a highway project. These different machines have different hydraulic requirements, and not all of them need an expensive axial piston pump to lift their bodies reliably.
For tippers up to approximately 14-16 cubic metres, an Eaton gear pump — the 4623, 5421, or 72400 series — delivers adequate flow at working pressure with fewer components, lower refurbishment cost, and faster turnaround when it fails. PumpGrid supplies refurbished Eaton tipper pumps with flow testing to confirm lifting capacity before dispatch.
Using the wrong pump type costs you either money (overspec) or performance (underspec). Use this guide:
| Eaton Pump | Type | Pressure | Flow | Common Tipper Application |
|---|---|---|---|---|
| Eaton 4623 | Gear Pump | 200 bar | 23 LPM @ 1500 RPM | 6-tyre tippers, 8-12 cubic metre body |
| Eaton 5421 | Gear Pump | 200 bar | 21 LPM @ 1500 RPM | Compact tippers, skip loaders |
| Eaton 72400-029 | Piston Pump | 250 bar | 29 LPM variable | Medium tippers 12-16 cubic metre |
| Eaton 3320 | Gear Pump | 180 bar | 20 LPM @ 1500 RPM | Light duty tippers, farm trailers |
| Eaton 70423 | Gear Pump | 200 bar | 23 LPM @ 1500 RPM | Replacement for 4623 variant |

Gear pump wear is concentrated on the gear teeth — when these wear, flow drops. We replace the complete gear set in every Eaton tipper pump refurbishment as standard. This single step restores volumetric efficiency to near-new specification.
We test flow output at 1,500 RPM against rated specification. If the pump doesn't reach rated flow, it's reworked before dispatch. Your tipper needs full flow to lift the body under load — a pump producing 80% of rated flow will struggle on a fully-laden body.
Eaton gear pump refurbishment is the most cost-effective hydraulic pump repair we offer — because the design is simple. The savings versus new OEM are significant, and versus a Sauer Danfoss piston pump for the same application, you save both on the pump cost and refurbishment cost.
All Eaton tipper pumps carry a minimum 3-month warranty. For tipper fleet operators ordering 5 or more units, we offer volume pricing and extended warranty options.
Act on these early — delayed replacement risks secondary damage to cylinders, motors, and valves.
