Our Industrial Rubber Rotary Lobe Pump is designed to handle viscous, fibrous, abrasive, and solids-laden products with ease. Its self-priming, reversible design and durable rubber lobes make it an effective alternative to Peristaltic and Progressive Cavity Pumps.
Available in nine sizes, the pump’s in-line configuration enables easy integration into existing pipework while delivering exceptional versatility.
Typical applications include:
| Max Capacity (m³/hr) | 300m³/hr |
| Max Pressure (m) | 50m |
| Max Temperature (°C) | 40°C |
| Housing | GG30 Cast Iron |
| Lobes | Cast Iron coated in NBR, SBR, XNBR, EPDM and FPM |
How does a Rubber Rotary Lobe Pump work?
Two lobes rotate within the pump housing without contact via timing gears in the gearbox. As they turn, fluid is drawn into expanding cavities, trapped between the lobes and casing, and conveyed to the discharge port, allowing solids to pass through with the fluid.
These pumps deliver a consistent flow rate regardless of system pressure, ideal for applications with varying discharge conditions or fluid properties. Constructed from wear-resistant components, they feature interchangeable elastomer-coated lobes, a front pull-out design for easy maintenance, and a range of drive options.
Design & Construction:
As positive-displacement rotary pumps, these industrial rotary lobe pumps deliver a consistent flow rate independent of system pressure across their range. This makes them equally suited to mobile applications with constantly changing discharge conditions and fixed installations handling fluids of varying viscosity and density.
Pump bodies are cast from GG 30 spheroidal graphite iron, with wear-resistant steel wear plates and a triple-seal design as standard. Lobes are available in a range of elastomer coatings – NBR, SBR, XNBR, EPDM and FPM – and a front pull-out design makes replacement quick and simple.
Multiple drive options accommodate site-specific needs, including ATEX-rated motors, hydraulic drives for truck mounting, and diesel or petrol drives for portable systems.
Built for arduous, challenging duty, each model is engineered to extend service life and reduce maintenance intervals. Every design has undergone rigorous laboratory and field testing, and each pump is individually tested before delivery.
