RV pumps are configured to meet your vacuum needs with a mode selector and 2 position gas ballast that allows either 60 g/hr or a class leading 220 g/hr (290 g/hr on RV12) of water vapour to be handled. This is ideally suited for your wet pumping applications such as freeze drying, extraction, filtration and gel drying. But it doesn’t stop there, these pumps truly are multi-purpose pumps, extremely versatile, perfect for many applications. For safe process and systems the built in anti-suck back protection prevents oil mist entering your system. The rapid closing inlet valve acts within 0.4 seconds of the pump stopping, providing reliable and safe operation in almost any application and thanks to the use of wide range motors the pump covers a wide range of possible voltage and frequency from two motor variants. We can also offer an RV to meet your specific requirements including PFPE prepared and ATEX approved pumps. Easy to maintain: the O-ring sealed sight glass makes visual inspection of the oil level and condition simple. The oil drain port is located at the end of the oil box for draining oil out of the pump. A large oil filling port and recess in the top of the oil box top makes oil top ups easy.
