Description
The Oliju SGR 50.220 400v (code 1200-0030) is the three-phase version of the SGR 50: a 2.2 kW sewage grinder pump with a 2″ outlet and a running current of 4.6 A. Oliju gives it a maximum head of 30 metres and a maximum flow of about 380 litres per minute, with around 21.7 metres still available at 200 litres per minute.
It is the highest-performing pump in the SGR range and the natural choice for a commercial site with three-phase power. For lower heads at 400v, the SGR 40 400v uses a 1½” outlet. On a single-phase supply, the SGR 50.220 Manual 230v gives the same head and flow.
The SGR 50 is the larger SGR body: cast iron pump body, open impeller and motor casing, a stainless steel shaft and a stainless steel cutter, with an oil-filled class F motor behind double seals, lip seals and a silicon carbide mechanical seal. It weighs 36 kg, has a front outlet for guide rail installation and comes with 20 metres of H07RN-F neoprene cable. Oliju rates it for immersion to 10 metres.
