Parker's three-piece cast iron gear pump construction — the PGP315, PGP330, PGP350, and PGP365 series — uses low-friction bushings and an advanced thrust plate design to hold up under high temperature and repeated pressure cycling, exactly the conditions a busy tipper truck's PTO pump faces on a mining or construction haul route. Flow ranges from 121 LPM (PGP315) up to 250 LPM (PGP350), giving a genuine option for larger tipper bodies where a smaller gear pump would be under-specified.
Parker Cast Iron Series — Matched to Your Tipper
| Series | Flow Range | Suited To |
|---|---|---|
| PGP315 | Up to 121 LPM per section | 12-16 cubic metre tipper body |
| PGP330 | Up to 151 LPM per section | 16-20 cubic metre tipper body |
| PGP350 / PGP365 | Up to 250 LPM per section | 20+ cubic metre body, mining tippers |

What Our Refurbishment Covers
Measured against Parker tolerance — the bushing design is what gives this series its high-temperature durability, so wear here is checked closely.
Inspected and reset to spec — this is what keeps the pump efficient even as oil temperature rises during repeated tipping cycles.
Replaced as standard on every unit.
Where fitted, auxiliary sections are tested independently to confirm each circuit performs to spec.
Verified output documented on the written test report before dispatch.
Why Heavy-Tipper Fleets Choose Parker Pumps From PumpGrid
Built for the Duty Cycle, Not Just the Pressure Rating
A mining tipper making 15-20 loaded trips a day puts real thermal and cyclic stress on its pump. The PGP series's cast iron, low-friction-bushing design is specifically engineered for that punishment.
Right-Sized Cost for Larger Bodies
Where a full piston pump might be more capability than you need, a correctly sized PGP350/365 delivers the flow a large tipper body needs at a lower refurbishment cost.
Fleet Pricing for Mining & Transport Contractors
Operators running multiple large tippers get volume pricing and stock reservation on repeat orders.
3-Month Warranty on Every Unit
Confirmed in writing, with replacement rather than repair for any refurbishment defect within warranty.
