Description
The Vort Buddy 400 Automatic (code 020-040) is a compact submersible dirty water pump for small sumps, cellars and drainage pits. It moves up to 133 litres per minute with a maximum head of 5 metres, from a 0.25 kW motor that draws just 1.7 A on 230v single-phase. A cable float switch runs it automatically, and the 1½” outlet takes 1¼” or 1″ hose through the supplied step adapter.
This is the smaller of the two Vort Buddy pumps, and the one to choose when the lift is short and the inflow is modest. At about 2 metres of head it still gives roughly 100 l/min, but output drops steadily as the lift increases. If you need to lift water higher or clear it faster, the Vort Buddy 900 uses the same body with a 0.55 kW motor, 233 l/min and 8.5 metres of head. For a narrow pit where a cable float cannot swing, the Sump Buddy uses a sliding tube float instead.
Both Vort Buddy pumps share the same plastic body, measuring 335 x 155 x 230 mm, with a vortex impeller recessed above the inlet. The impeller spins the water into a whirlpool that carries soft solids out through the 1½” outlet without most of them touching the vanes, so the pump is less prone to clogging than a clean water drainage pump. A step adapter hose tail for 1¼” and 1″ hose and 10 metres of power cable come with the pump.

The Vort Buddy 400 is a light-duty domestic pump. It is not for sewage, toilet waste or sanitary items, which need a dedicated sewage pump. Its low head also makes it a poor choice where the water has to go up a flight of stairs or out through a long hose run; check the curve below against your lift before you buy.
