Goodwin International Limited
Hose and Accessories
Goodwin recommends all its submersible slurry pumps are suspended on chains, with a Bauer type adapter for coupling to the pump followed by a length of reinforced flexible hose before connecting to any rigid pipe work. This enables the pump to operate correctly when it is in thick heavy slurries, as when the pump is started and slurry has settled around it there is a very high energy start as the motor is direct on line which makes the pump kick. As the pump is suspended on chains, the "kick" it breaks away from any settled slurry allowing standing water to get to the impeller by flowing around the pump body as it has broken away from the slurry. As soon as this has happened the pumps agitator starts emitting its hydraulic shock wave 'sphere of influence', putting dense particles into suspension to be pumped with ease. Goodwin hoses are supplied with PN16 flanges on both ends as standard.
