Installation options Submerged installation on auto-coupling, types S and C Submerged installation on auto-coupling system requires a base plate with a 90° bend, fixed to the bottom of the pit. When lowered into the pit along the guide rails, the pump automatically connects to the base plate. The flexible neoprene SmartSeal ensures a leak-proof connection between the pump and the auto-coupling. Type S: To prevent sedimentation of sludge at intermittent operation, we recommend a stop level corresponding to the top of the pump housing. For sufficient cooling at continuous operation, the liquid...

Grundfos SuperVortex impellers A unique impeller design The unique design of the Grundfos SuperVortex impellers provides high pumping efficiency and less downtime. With a flow range from 4 l/s, the Grundfos SuperVortex-impeller pumps are the optimum solution for all small pumping stations. No clogging or jamming In a SuperVortex-impeller pump, the flow is entirely outside the impeller. The design of the impeller ensures that long fibres, rags, etc. pass freely through the pumps without getting caught and without causing clogging or jamming. This means less downtime and, consequently, reduced...

Grundfos channel impellers Large free passage for superior solids handling Compromising on the ability to handle solids in order to obtain higher pumping efficiency substantially increases the risk of clogging. More clogging means more downtime and increased operating costs. The Grundfos channel-impeller pumps provide high efficiency and excellent non-clogging capabilities. The channel impellers are designed with a large free passage Ø 80 mm. Self-cleaning impeller On Grundfos wastewater pumps smaller than 12 kW, the bottom part of the channel impellers feature specially designed auxiliary vanes....
