Pentair’s borehole range centres on the Nocchi Dominator, a multistage submersible built for clean water. It comes in 4-inch and 5-inch bodies, so there’s an option whether you’re working with a narrow domestic well or a wider bore. Typical duties include wells, collection tanks and system pressurisation.
Casings and suction screens are stainless steel, designed to resist the wear that sand causes over time. Flows run from around 55 to 140 litres per minute, with heads to roughly 65 metres, discharging through a 1¼” BSP female outlet. An integrated non-return valve comes fitted as standard, so that’s one less part to buy.
Pumps arrive ready to lower into position, with power cable and nylon suspension rope supplied. Choose manual models, or automatic versions with a float switch if you’d rather the pump looked after itself in a tank. These are clean water pumps rated to 40°C, so give us a call if your bore runs dirty.

The range is built around the Nocchi Dominator multistage submersible, available in 4-inch and 5-inch diameters. Both manual and automatic float switch versions are offered, all designed for clean water.
The hydraulic system resists the corrosive action of sand, and the stainless steel suction screen keeps larger particles out. Even so, these are clean water pumps, so heavily silted bores need a different pump type.
Common uses include lifting from traditional wells, drawing from collection tanks and lakes, and pressurising domestic supply systems. Garden irrigation, crop spraying and surface watering are equally well covered.
Models marked AUTO include a float switch for automatic level control; MAN models are manual. Manual pumps can still be automated later using a pressure controller.
