Description
The Dreno Compatta 22TG (code 200-0023) is a cast iron submersible sewage pump with a vortex impeller, for raw sewage, foul water and effluent. It pumps up to 420 litres per minute and reaches a maximum head of 8 metres from a 0.56 kW motor on 400v three-phase, a three-phase supply, drawing less current than the single-phase equivalent. It is the smallest pump in the range, sized for a single house or small office where the sewage has to be lifted a few metres to a gravity drain.
This is the automatic version, fitted with a float switch that starts the pump as the level rises and stops it before the chamber runs dry. That makes it the right choice for a lifting station or sump that has to look after itself, where a manual pump would rely on someone switching it on and off. Dreno Compatta 22M is the 230v manual version. Dreno Compatta 22T is the same pump with manual operation. The Dreno Compatta 32T is the next size up, 480 l/min to 10 m.
The vortex impeller sits back from the inlet and moves the liquid by spinning it, so solids up to 40 mm pass through without touching the impeller blades. That is why the Compatta copes with sewage that would block a standard drainage pump. The pump body, motor casing and impeller are GG20 cast iron, with a mechanical seal on the pump side and a lip seal on the motor side. It has a 2″ outlet, 10 metres of power cable, and can be submerged to 20 metres. Maximum liquid temperature is 40°C. For a permanent chamber, the Dreno Easy B guide rail kit (code 200-0432) lets the pump be lifted out for servicing without entering the chamber.
