Tuke and Bell is one of the UK’s leading manufacturers of sewage purification equipment with ninety years experience in design and production. The latest computer aided design systems are used to produce a wide range of high quality equipment, serving the needs of both the water industry and domestic customers. The Rolls Rotary crude sewage pump was first designed and built by Tuke & Bell in the 1950’s, and became an overnight success. Thousands have been supplied all over the world, many of which are still operating today with minimal maintenance. The Rolls Rotary is ideal for delivering small quantities of crude sewage, and is easy and inexpensive to service.

The pump is mounted at ground level and is suitable for dealing with sewage from isolated houses, office blocks, garages, warehouses, etc., and especially for discharging to package sewage treatment plants such as Biostats, Rotating Biological Contactors (RBC’s), BAF and SAF plants, when a gravity sewer is not available.

The Rolls Rotary is a glandless, positive displacement pump. The shaft is eccentric which provides orbital movement of the rubber rotor, extremely quiet in operation and requires minimal maintenance. No lubrication is necessary.
