Centrifugal process pumps PROCHEM series

Centrifugal Pumps Equipped with closed impellers for clear or slightly cloudy liquids

The PROCHEM RN - RNS series are centrifugal pumps equipped with closed impellers, suitable for the conveying of clear or slightly cloudy liquids, mainly used in the chemical and pharmaceutical sector.

• Flowrate up to 2,600 m³/h
• Head up to 140m

Innovative components assure an high fluid dynamics efficiency

Rolling-contact oil lubricated bearings,  for long service life and high reliability
Heavy duty pump shaft guarantees high reliability and low deflection for a perfect seal
Protected shaft from the liquid conveyed (1st - except for RN 32-125, 2nd, 3rd support) in order to prevent corrosion and to allow the use of materials with high-performance mechanical characteristics
Extremely rugged bearing support constructed following the BACK PULL-OUT system  to facilitate maintenance
The casing is the result of an innovative design with trapezoidal volute  to reduce loss and increase the efficiency of the pump.

For clear or slightly cloudy liquids

The RN - RNS series are centrifugal pumps suitable for the conveying of clear or slightly cloudy liquids, mainly used in the chemical and pharmaceutical sector.

Wide range of configurations

Wide range of stainless steel materials and shaft sealing configurations (single or double mechanical seals) to meet the highest demands in the chemical industry.


Heavy duty solution: RKNS with vortex impeller

The recessed vortex impeller, together with the casing design, allows the RKNS to reach a higher level of efficiency and performance.
The reinforced support with protected shaft is particularly suitable for heavy duty applications, involving, for instance, thick and/or viscous liquids and it guarantees high reliability and long life.

No clogging

The RKNS series is suitable for the conveyance of solutions with suspended crystals, muddy and/or viscous liquids, with suspended particles or fibrous materials, chemically inert or aggressive, without any problems of clogging.
