Submersible pump for dirty water UNILIFT AP 12.40.08.3 0.8 kW 3x400V 10 m 96001791

Submersible dirty water pump – a reliable solution for home and industry

This efficient Grundfos UNILIFT AP 12.40.08.3 submersible pump, powered by 3x400V and with a power of 0.8 kW, is designed to operate in harsh conditions where drainage of water with contaminants is required. It will work well in both domestic and industrial applications, offering reliable operation and long service life. The pump design allows for effective pumping of surface water, groundwater and non-fecal sewage, even those containing solids up to 12 mm in diameter.

Construction and application – durability and versatility

The UNILIFT AP 12.40.08.3 pump is characterized by a solid construction with a housing made of stainless steel 304 (1.4301) and a motor housing made of stainless steel 316 (1.4401). This ensures high resistance to corrosion and mechanical damage, guaranteeing long-term operation even in an aggressive environment. The impeller made of stainless steel further increases the pump's resistance to solids in the pumped liquid. Therefore, the pump works perfectly in emergency situations, such as basement flooding, draining water from retention tanks or drainage wells. It can also be used to pump industrial wastewater based on water (e.g. from industrial laundries) and non-fecal sewage.

The pump has an ISO 7-1 / EN 10226-1 outlet connection with an internal cylindrical BSPT-Rp thread with a diameter of 1 1/2 inch (40), which facilitates its integration with existing hydraulic installations. The length of the power cable is 10 m, which provides convenience during installation and use. The motor insulation class F guarantees safe and reliable operation in a wide range of ambient temperatures (0…55°C) and pumped liquid temperatures (0…55°C). The IP68 protection class ensures complete sealing and the possibility of immersing the pump to a depth of 7 meters.

Key features and benefits
