Scheppach GP650 review

3 300 l/h, 35 m head, 3.5 bar and an 8 m suction height, with G1" suction and delivery ports.

The bottom line The first listing here to give all four hydraulic figures — flow, head, pressure and suction height — and both port threads. 3 300 l/h at zero head, 35 m at zero flow, 3.5 bar, 8 m of lift, on G1" connections that take ordinary garden fittings.

What the maker prints on its own page

A powerful 600 W motor delivering up to 3 300 l/h, stated as ideal for garden watering and for drawing water from wells, cisterns, rain butts and ponds. A head of up to 35 m, 3.5 bar of delivery pressure and a suction height of up to 8 m supply lawn, beds, hedges and irrigation systems. Durable G1” suction and delivery connections let the pump be joined to ordinary garden hoses, fittings and irrigation systems. An integrated overload protection guards the motor against overheating and a carry handle allows transport.

Four figures, which is the whole curve

Flow, head, pressure and suction height. Nine pumps on this shelf and this is one of the few to publish all four.

The two that matter together are flow and head, and they are the opposite ends of one line:

3 300 l/h is measured with the outlet open and nothing to lift. 35 m is measured with the outlet closed and nothing moving.

Real operation is somewhere between, on a curve no domestic listing publishes. A pump with a high head has pressure in reserve when there is also flow, which is why the head figure matters even though you will never see 35 metres.

The thread, named

G1”. That is a parallel pipe thread, and the standard it comes from is titled, in effect, “pipe threads where pressure-tight joints are not made on the threads”.

Which means the joint is sealed by a flat washer against a face, not by the thread. A G-fitting screwed on hard without its washer will leak, and tightening it further deforms the plastic.

Naming the thread family saves a buyer the leak. Most of this shelf gives an inch size and stops.

What is not stated

The housing and impeller materials, which the cheaper pump below this one names. And no drain plug — on a machine that will spend a winter somewhere cold, that is the omission worth checking before buying.

Availability

From 50 € to 60 €, that being the spread across the German and French Amazon stores on the day of the survey.

Listed and unsold: the American, British, Italian and Spanish Amazon catalogues hold the reference with nobody behind it.

What this machine usually gets asked

Is 35 m of head the same as 3.5 bar?

Near enough: one bar is roughly ten metres of water column, and the listing gives both, which is the correct way to publish it. Both are measured at zero flow — the outlet closed — and neither happens while water is moving.

What does G1" mean?

A parallel pipe thread in the one-inch size, from the standard whose own title says the joint is not sealed on the threads. It is sealed by a flat washer against a face, which is why a G-threaded fitting without its washer leaks however hard you tighten it.

Can it run a sprinkler at the end of a long hose?

At 3.5 bar it has pressure in reserve for that. What arrives depends on the hose bore, its length and every quick coupling in between, and this page prints the pump figures rather than predicting the result at your sprinkler.

Who this one is for

A medium garden watered from a butt or a cistern, where the numbers need to be checkable before buying
