Pump sales, service and custom fabrication.
Shaw Diesels designs, builds, supplies and services diesel-powered pump sets for borehole, irrigation, dewatering, slurry and industrial applications across New Zealand and the Pacific.
We fabricate complete pump sets in-house — pairing Lister Petter diesel engines with leading pump brands, to build units matched to your specific application. From a simple hand-start borehole pump for a Pacific Island community through to a trailer-mounted irrigation set for a dairy farm or a custom-built slurry pump for a mining operation, we build it, install it and keep it running.
Every pump set we build is available new, or we can recondition and rebuild existing units. We also service and repair pump sets from other manufacturers, and we can repower electric-driven pump systems to diesel where mains power isn’t available or reliable.
Find the right pump for your application.
Not sure which type of pump you need? Here’s a quick guide to our three main categories — or contact us and we’ll help you work it out.
Borehole Pumps
Diesel-powered borehole pumps for underground wells, rural properties, farms and Pacific Island communities.
Irrigation & Water Pumps
Diesel pump sets for farm irrigation, rural water supply and agricultural operations. Towable, remote-start and trailer-mounted.
Custom Solutions
If an off the shelf solution won’t work we have a design and fabrication team that can tailor a diesel engine and mounting package to suit your application, including, Iron sand slurry pumping, concrete pumping and hydraulic power packs.
Built in-house. Built to last.
We don’t just sell pumps off a shelf — we fabricate complete pump sets to match your application.
Shaw Diesels builds diesel-powered pump sets from the ground up. We pair proven diesel engines — primarily Lister Petter — with quality pump units from Mono and other leading manufacturers, mounted on fabricated steel base frames or trailer chassis. Every unit is assembled, tested and commissioned in our workshop before it leaves.
This means we can build exactly what you need: the right engine, the right pump, the right configuration for your flow rate, head pressure, fluid type and site conditions. Standard off-the-shelf pump sets work for simple applications — but when the job is more demanding, a purpose-built unit is the better investment.
Pumps for every application.
Shaw Diesels supplies and services diesel-powered pumps across a wide range of industries and applications:

Borehole & well
Deep well extraction for rural properties, farms, communities and Pacific Island water supply.

Irrigation
Broadacre, pasture, orchard and vineyard irrigation for dairy, cropping and horticulture.

Rural water supply
Pumping water from rivers, streams, dams and bores to storage tanks and troughs.

Dewatering
Construction sites, excavations, flooded areas and mine dewatering.

Slurry & mining
Ironsand slurry, mineral processing, dredging and abrasive fluid handling.

Concrete pumping
Diesel-powered concrete pump sets for construction.

Effluent & wastewater
Dairy shed effluent, piggery waste, municipal wastewater and sewage transfer.

Industrial & process
Factory process water, cooling systems, tank transfer and general industrial pumping.
New, reconditioned and rebuilt.
Shaw Diesels supplies new pump sets built to your specification, as well as quality reconditioned and rebuilt units for operations where a new pump isn’t the most cost-effective option.
Every reconditioned pump set is stripped, inspected, rebuilt with genuine parts where required, tested and backed by our warranty. For existing pump sets that need new life, we can rebuild the engine, replace the pump, upgrade the base frame or repower from electric to diesel.
- New pump sets — custom-built to your specification using Lister Petter, Mono and other quality components
- Reconditioned units — fully rebuilt pump sets at a lower price point, inspected and tested
- Engine rebuilds — new life for existing pump sets with a tired engine
- Electric to diesel conversion — repower electric-driven pumps to diesel for off-grid or unreliable mains sites
Pump service, repairs and parts.
We service what we sell — and plenty of pump sets we didn’t.
