The SR RB pump is a high-quality pump with channel impeller in a modular construction with connections according to ISO 2858-5199. Available in sizes from pressure connection DN65 to DN300. The unique closed channel impeller has specially designed blades which enable a large free passage and low NPSH values with high efficiency.
Flanges follow UNI EN 1092-1 PN 10.
Our RB pump series is available in the designs as shown below.
All these designs are also available in Atex version zone 1 and 2.
With a channel impeller, the entry and exit velocities are low compared to a traditional closed impeller. The efficiency of this channel impeller is therefore comparable to the efficiency of a closed impeller, but with a number of clear advantages over the closed impeller; low NPSH, pumping of solids in the liquid, low noise production and suitability for viscous liquids. These features make the RB pump with channel impeller the perfect pump for many applications.
The special closed channel impeller guarantees very high efficiency with relatively large capacities.
Modular heavy-duty bearing bracket construction which, when fitted with the heaviest series of ball bearings, has a lifespan of 100,000 operating hours
The seal chamber in the RB series has a modular design, so that almost all possible shaft seals can be mounted in the RB pump. The modular construction also ensures that the type of shaft seal can be easily changed.
