HVVU and HVVS – Sewage Pumps

Light ground water and sewage pumps

Mamec Oy’s fixed-mounted HVVU-wastewater pumps are suitable for pumping both wastewater and groundwater. They can be also used for pumping many chemical liquids (for example, ferrous sulphate).

The pump volute of our wastewater pumps is moulded acidproof steel plate. The bearing cartridge and impeller is easy to changed. We also offer a portable HVVS wastewater pump that is for example suitable for emptying boats, columns pits
and oil tanks. The pump can also be used for keeping an ice hole opened.


All steel parts in contact with liquid are of acid-proof steel EN 1.4404 Seals are of Viton rubber and bearing is of carbon graphite teflon.


Our wastewater pumps are designed to be easy to maintain. The bearing cartridge and impeller is easy to change. The entire pump housing is made of moulded acid-resistant steel plate EN 1.4404. All components are attached to each other with wedge,
bolt or cotter pin and are thus easily replaceable.
