Super U Series

Scroll through our range of pumps


Solids handling wastewater and slurry pumps

These pumps are among the most efficient self-priming, solids-handling pumps available. Their unique hydraulic design and smooth wall volute casing minimise friction loss and drag. The multi-vane, open impeller is designed for high efficiency operation yet can still handle limited solids. The pumps not only deliver high efficiencies (up to 75%), they also perform efficiently across a broad operating range. Varying demands that cause pumps to operate right or left of its best efficiency point will affect operating efficiency by only a small percentage. Useful features include external shimless adjustment, dual protection of bearings and an “easy grip” cover plate handle.
