RENA

Utilisation

Centrifugal pumps according to DIN 24255 completely made in AISI 316L. Suitable for water supply in civil and industrial systems, pressurisation, fire-fighting systems, heating and air-conditioning systems, cooling towers and washing systems.

Technical description

·stainless structure => low weight, high corrosion resistance and long durability
·high power output, efficiency and quiet operation is secured by spiral body and smooth internal walls
·shaft diameter of 19 mm
·spherical shape of the spiral body allows high inside pressure in the pump and its light structure
·delivery part situated in the axial plane and the flange girder provides maximal resistance against deformation caused by piping system during the operation
·exchangeability, connections according to DIN 24255
·no damage of pump at water freezing
·simple structure of pump enables easy dismantling and exchange of impeller, shaft, bearings and stuffing box without disassembly of pump body from the suction and delivery part
·all these advantage are leading to higher operational efficiency, increase of flow rate range and lower operation costs

Material

Body of pump, shaft, impeller, casing cover and drain plug are made of CrNi steel 1.4301 according to DIN 24255.
