GMP Electric Surface Trash Self Priming Pump – B2KQA-ST TRASH EAR4 400v

Description

The GMP B2KQA-ST EAR4 400v electric trash pump (code 070-004) is an electric self priming surface trash pump in cast iron, for dirty water and wastewater carrying solids. It pumps up to 440 litres per minute and reaches a maximum head of 17 metres from a 1.5 kW motor on 400v three-phase, a three-phase supply, drawing less current than a single-phase motor of the same size. It is the 2″ model, moving up to 440 l/min for site drainage and dirty water transfer.

The GMP B2KQA-ST EAR3 is the same pump for 230v single-phase. The GMP B3KQA-ST EAR6 is the next size up, 850 l/min to 15 m.

The pump sits on the surface and lifts water from up to 6 metres below it. A multi-blade impeller handles dirty water and solids, and an inspection door on the casing lets you clear a blockage without dismantling the pump. A non-return valve on the inlet keeps the casing full after it stops, so it re-primes quickly on the next cycle. The casing, inlet flange and impeller are cast iron, with a stainless steel shaft and silicon carbide mechanical seal, and it handles liquids up to 60°C. Models of 4 kW and above are supplied on a skid plate.
