Engine-driven watermaker
Turns motoring and engine-charging time into fresh water. The pump runs off your engine's mechanical power, so it makes large volumes quickly without drawing heavily on your batteries.
Turns motoring and engine-charging time into fresh water. The pump runs off your engine's mechanical power, so it makes large volumes quickly without drawing heavily on your batteries.
The high-flow, high-pressure pump mounts to your main engine or auxiliary generator and runs through an electric clutch on a standard single "A" section belt.
Built on our high-volume pump platform. Start at 80 litres per hour and add membranes to reach 160 or 240 as your needs grow.
The pump sits on the engine. Filters, controls and membranes go wherever there's unused space elsewhere on board.

Add-on kits to reach 160 L/h with two membranes, or 240 L/h with three.
Our short-format carbon fibre vessel, making 115 L/h. Suits cramped engine rooms.
For smooth, horizontal belt tensioning.
For easy, vertical belt tensioning.
Runs a 2-minute flush every 7 days while you're away from the boat.
Added protection in muddy rivers and silty coastal anchorages.
Every engine offers different options for a power take-off, so mounting the pump is the main variable in an engine-drive install. Because engine spaces vary so much, we make two tensioning options.
CNC cut from 8mm aluminium, mild steel or stainless steel, with 50mm of sliding belt adjustment. Suits horizontal belt tensioning.
Pivots like an alternator bracket, for pumps fitted above or below the engine. CNC cut from 8mm mild steel or stainless steel, TIG welded, with a 10mm stainless pivot pin and tensioning bolt.
| Output | 80, 160 or 240 L/h, with 1, 2 or 3 membranes |
| Rated at | Seawater at 25 °C and 35,000 ppm salinity, at 800-850 psi |
| Drive | Stainless steel high-pressure pump with a 12V electric clutch, driven by one "A" section (13 mm) belt from a pulley on your main engine or generator |
| Engine speed | Works from 1030 to 2450 RPM. The crankshaft pulley size (5" to 8") sets the range, so you can match it to your usual RPM. The pump pulley is 7". |
| Power from the engine | Up to 2.15 kW (about 3 hp) |
| Electrical draw | Clutch about 4 A at 12V (2 A at 24V); boost pump about 4 A at 12V (2 A at 24V) |
| Water quality | About 120 ppm total dissolved solids with a new membrane, rising to about 300-400 ppm as the membrane reaches 3-4 years old. |
| Membrane vessels | Carbon fibre, rated to 2000 psi. Each vessel is 90 mm x 1190 mm and holds one 2.5" x 40" membrane. |
| High-output option | Short-format carbon fibre vessel: 115 L/h from one 4" x 21" membrane, in a vessel 115 mm x 690 mm. Fits the Engine Drive and AC systems. |
| High-pressure pump | 240 x 320 x 190 mm (W x L x H), 11 kg. Turns in either direction. |
| Other components | Control panel 200 x 165 mm; sample/tank valve panel 130 x 75 mm; 12V boost pump 100 x 100 x 70 mm; seawater filter 400 x 320 x 130 mm; charcoal flush filter 400 x 370 x 130 mm (H x W x D) |
| Suits boats | Boats with high water use |
| Warranty | 12 months, plus 5 years on the carbon fibre pressure housings and end caps |
| Price | From NZ$11,880 + GST with one membrane. Two- and three-membrane setups on quote. |
