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.
Design features & Benefits:
• Sealless – Minimising the risk of leaking.
• Efficient – Low power consumption.
• Self-priming – Up to 9 metres.
• Shear sensitive – Very gentle on the product being pumped.
• Capable of running dry indefinitely – Without the need to install any other device.
• Reversible flow ability – Ideal for tank emptying and fluid transfer applications.
• High dispensing accuracy – Excellent for dosing applications.
• Easy to clean as the inner hose is the only part in contact with the product.
• Suitable for food-grade applications – FDA approved.
• Resistant to abrasion and corrosion – Optional connections and coating materials.
• Requires low maintenance – Economical to run.
• Hose leakage detector available – Recommended when pump is working unattended and for corrosive liquids.
Typical Applications & Industries:
• Chemical Dosing.
• Water Treatment.
• Food/Beverage Transfer.
• Construction.
• Sampling.
• Mining.
• Paper Industry.
• Agriculture.
• Pharmaceutical.
• Industrial & Chemical Process Transfer – Glue, Resins, Ink, Paint, Anti-foaming, Dyes, Detergents, Oils, Concrete, Mud, Sludge, Sewage.
Accessories:
• Pulsation Dampener – This is fitted downstream from the pump to ensure a smooth and stable flow. This is particularly beneficial when using ancillary equipment such as pressure switches and flow meters or when measuring the product for bottling, packaging etc.
• Hose Leakage Sensor – This is connected to the pump casing and wired to an external control panel. The sensor detects if the internal rubber hose has broken and signals an alarm to warn the operator maintenance is required. This is particularly useful when the pump is unmanned, handling hazardous fluids or running continuously for critical applications.
• Anti-corrosive Coating – The pump casing can be coated in Halar (ECTFE) for corrosion resistance. This is recommended when the pump is installed in a corrosive or hazardous environment.
• Variable Speed Drive – The pump is supplied fixed speed as standard, an inverter can be fitted to the motor to enable variable flow rates, this is excellent for dosing and flow critical applications.
• Air Operated Vacuum Pump – This is recommended for high suction lifts. The vacuum system ensures the hose does not collapse under extreme conditions and facilitates easier priming for the pump.
• Screw Hopper Feeder – For dry and highly viscous fluids, a hopper/screw system is installed on the inlet side of the pump to enable easy flow of the product into the pump.
• Mobile Trolley – The pump can be supplied on a mobile trolley for moving around site. Bespoke dimensions and materials are available on request.
