370W Peripheral Water Pump

Put those two numbers side by side and the character of the machine appears. Thirty metres of head from a half-horsepower motor is a lot of push — enough for a three or four storey house, or a long uphill run to a tank. But 2100 litres an hour is 35 litres a minute, which is a steady flow rather than a torrent. A peripheral impeller gets its pressure by driving water round and round the outside of a small vaned wheel, picking up energy on every pass. That design produces high head from a small motor, and low flow is the price of it.

That trade suits a specific set of jobs very well. Filling a roof tank from a ground sump. Boosting mains pressure in a house where the shower on the upper floor dribbles. Feeding a line from a well to a tank up the hill. Supplying a small irrigation line. In all of those the question is whether water arrives at height at all, not how many litres a minute it arrives in, and this pump answers that question cheaply and on a small supply.

Suction lift is 8 metres, which means the pump can pull water up 8 metres from below its own position before it stops being able to prime. That is the figure to measure against the drop from the pump down to the water level in your well or sump — not the depth of the well itself, which is a common and expensive confusion. If the water sits deeper than 8 metres below the pump, no surface pump of this kind will lift it and you need a different arrangement.

Ports are 1 inch in and 1 inch out, which matches the standard domestic pipe sizes here and keeps installation straightforward.

The buyers are households boosting pressure or filling roof tanks, plumbers installing and replacing domestic pumps, small guest houses and shops, and smallholders on short irrigation runs. Hardware dealers sell it as the everyday domestic pump.

Two things kill a pump like this. Running it dry, even briefly, because the water it moves is also what cools and lubricates it — so the foot valve and the suction line must be airtight, and the pump must be primed before it starts. And running it against a closed tap for long periods, which turns all that motor power into heat with nowhere to go. If you need considerably more flow at a similar height — filling a large tank quickly, or feeding several outlets at once — look at the 750W centrifugal pump instead, which moves three times the water.
