Why We Use Industrial-Grade Pumps
The high-pressure pump does the hardest job on any watermaker: pressurising seawater to around 800 psi, hour after hour, in the most corrosive environment there is. It is the single component that decides whether a watermaker lasts two seasons or twenty years.
So we don't fit generic pumps and hope. Every LEDI system is built around a proven, USA-made industrial pump — the same units running in commercial duty around the world — each chosen for one specific job, and backed with genuine spares held at our Gold Coast workshop.
Scout runs the Pumptec 107SS
The Scout's 10 and 20 LPH output comes from a Pumptec 107SS high-pressure plunger pump — machined in the USA from a single billet of marine-grade stainless steel, and built to be rebuilt.
- Oil-free ceramic plunger — no oil changes, ever, and no oil anywhere near your drinking water.
- One billet of marine-grade stainless — no seams, no plated mild steel, nothing for salt to get into.
- Quiet, low-draw 12V operation — runs happily off a battery bank and solar surplus.
- Field-serviceable — plunger, seals and valves are all replaceable without sending the unit away. We publish the parts list and stock the kits.
Nomad runs the CAT Pumps 2SFSEEL
The higher-output Nomad steps up to the CAT Pumps 2SFSEEL — a best-in-class compact direct-drive plunger pump from the company that has set the standard for industrial triplex pumps since 1968. There's a reason they're known as “the pumps with nine lives”.
- Compact direct drive — the pump couples straight to the motor. No belts, no pulleys, no alignment to drift.
- Triplex plunger design — three solid ceramic plungers deliver smooth, low-pulsation flow at 800 psi.
- 316 stainless liquid end — engineered specifically for continuous seawater reverse-osmosis duty.
- Headroom for 40, 60 and 80 L/h — sized so the Nomad never has to run flat out.
- Standard seal and valve kits — genuine CAT Pumps service parts, no proprietary lock-in.
Serviced, not binned
A consumer-grade pump is a throwaway part — when it fails, the watermaker is done. An industrial pump is a platform: every wear part has a published spec and a genuine service kit behind it.
We hold seal kits, valve kits and spares for both pumps on the Gold Coast, ship them Australia-wide and internationally, and we'll talk you through a rebuild on the phone. Both pumps are covered by the same 2-year LEDI warranty as the system they power — and we service every unit we've ever built.
