Higher Performance
to meet every Challenge
Various challenges – individual solutions:
HOMA submersible wastewater
pumps are designed for pumping
sewage, sludge, effluents or surface
water, including liquids containing a
large proportion of solid or fibrous
matter. They are installed in domestic,
municipal, industrial and agricultural
pumping applications.
For chemically aggressive liquids,
specific components like impellers,
volutes or complete units are also
available from high-resistant materials
like stainless steel, duplex or bronze.
