The RBT peristaltic hose pumps are high pressure positive displacement pumps, these range of pumps have a max. design pressure of 15 bar, (150 metres), meaning they have the ability to transfer highly viscous fluids at long distances/high pressures making these range of hose pumps quite popular within the mining and construction industry. Our RBT pumps are available with integrated frequency drives, VFD rated drive units, certified ATEX, (explosion proof) motors as well as hydraulic motors, these units are also equipped with reinforced hoses and rotors, heavily engineered integrated bearings, enlarged PU rollers as well as our patented clamping system making them suitable for pumping almost any fluid.
The RBT series peristaltic pump, also known as a hose pump, is part of the positive displacement volumetric pump group. These pumps have quite a simplistic yet extremely robust design that enables them to be used for the most difficult of applications, such as transferring high viscosity products and fluids where a high concentration of solids is present, many of them being applications where other pumps would fail. Typical fluids include; Glue, Resins, Ink, Paint, Anti-foaming, Dyes, Detergents, Oils, Concrete, Mud, Sludge and Sewage/Effluent.
As one of their popular names indicates ‘hose pumps’, the pumping action is performed by a combination of a rubber hose located inside the casing of the pump and a rotor with a set of rollers or pads/shoes compressing the hose as they rotate. By pressing the hose whilst continually rotating, the shoes push the fluid from the inlet side and towards the discharge side of the hose. This gentle pumping action means the flow rate achieved is directly proportional to the speed the shoes rotate and squeeze the tube/hose.
The unique pumping action creates a negative pressure on the suction side of the pump of up to 9 m.w.c., meaning the pump can self-prime and reach a suction lift of up to 9 metres vertically, this combined with the ability to run dry indefinitely and handle gasses makes the peristaltic hose pump the ideal solution for most pumping applications.
Another advantage of these pumps is how simple and economical they are to maintain. This is the due the fact that the hose is both the only wearing part in the pump and the only part that is in contact with the fluid.
The RBT range can be supplied either fixed speed or variable speed and is fully reversible. There are a wide range of accessories available to provide a complete custom solution for most applications, these are detailed below.
