Centrifugal pump PROCHEM

for liquids

RN - RNS centrifugal pumps are equipped with closed impellers and RKNS with recessed open impellers. RN - RNS 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. Heavy duty solution: RKNS The recessed 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.
