A truly multi-purpose pump

The RV is a truly versatile pump for operation throughout your operations, perfect for wet applications, dusty applications and clean dry applications. We can also customise your RV series to meet your specific requirements, including PFPE prepared and ATEX approved pumps.

Excellent vapour handling capacity

The RV series of pumps has the highest vapour handling capacity of any rotary vane pump. This is ideally suited for your wet pumping applications such as freeze drying, extraction, filtration and gel drying.

Safe for your process and systems

The best-in-class anti-suck back protection prevents dust or oil mist from entering your system. The fast-acting automatic inlet valve acts within 0.4 seconds – providing reliable and safe operation in almost any application.

One-size fits all motor

The universal motor in the pump covers the widest possible voltage and frequency range from a single motor. If required, you can choose pumps with flameproof ATEX approved motors.

Designed for easy maintenance

You can service and replace parts without dismantling the pump mechanism. All parts self-align, eliminating the need for special assembly. You can use a one size hex-head wrench to dismantle all parts
