For demanding liquids
PROMIX process pumps are designed for pumping chemically inert or aggressive liquids, including viscous media with a high content of solid particles and sludges.
Robuschi PROMIX
PROMIX is a series of single-stage horizontal process pumps for pumping viscous and aggressive liquids and liquids loaded with solid particles.

- RACN / RACNS – open channel impellerA version with an open channel impeller and large passages between the vanes for dense, viscous media and for liquids with a high proportion of non-fibrous solid particles. It is also suitable for pulp stock and similar suspensions. The casing has a replaceable wear plate that is adjusted from the outside in order to maintain efficiency over time.
- RCN / RCNS – closed channel impellerA version with a closed channel impeller for liquids containing non-fibrous solid particles, where reliable hydraulics without clogging are important. In this version the casing is fitted with a replaceable wear ring, so it is suitable for demanding process applications with particles where there is no pronounced abrasion.
- RCPN / RCPNS – for abrasive media containing solid particlesIn terms of construction it is based on the closed channel impeller like the RCN series, but it is intended for more abrasive media. Instead of a wear ring it uses a replaceable wear plate in the casing, which improves resistance when pumping sludge suspensions and other liquids containing abrasive particles.
- RKC / RKCS – vortex version with a recessed impellerA version with an open recessed impeller that creates a pumping vortex. The liquid therefore passes through the pump without entering the impeller channels directly, which enables reliable pumping of viscous media, particles, fibrous contaminants and also liquids with dissolved air without the risk of clogging.
- Reinforced versions – RACNS, RCNS-RCPNS, RKCSThe RACNS, RCNS-RCPNS and RKCS versions have a new reinforced support with more robust bearings, a protected shaft, greater rigidity and lower vibration. The dimensions and the connections remain the same as on the previous models, so replacement is simpler.
Benefits
Impellers with large passages
Specially designed impellers with large inlet openings enable reliable transfer of liquids containing particles and reduce the risk of clogging.
High energy efficiency
The optimised impeller geometry and hydraulic design enable high operating efficiency even when transferring dense and demanding media.
Reduced component wear
The wide flow passages in the casing and the impeller reduce the liquid velocity and the wear of the internal components, which extends the service life of the pump.
Easy maintenance
The design with a back pull-out system allows fast servicing without dismantling the piping, which shortens the maintenance time.
