North Ridge VPM, VPS & VPL Liquid Ring Vacuum Pumps

NR-VPM / NR-VPS & NR-VPL Liquid Ring Vacuum Pumps Flow RateUp to 450 m³/hHead (Pressure)Up to 33 mbar (0.033 bar)Sizes AvailableDN40 & DN80Operating TemperatureUp to 100°CConstruction MaterialsAISI 316 / TITANIUM / HASTELLOY C North Ridge Chemical pumps are heavy duty pumps designed for handling acids, highly corrosive chemicals and hazardous liquids in general, our NR chemical pump range has over 17 different pump types, with a wide choice of high grade chemical resistant construction materials such as PP, PVDF, AISI & ASTM 316 Stainless Steel and TITANIUM. Due their great chemical resistance and vast pump range NR pumps can be used for wide range of liquids, some of the most common applications are chemical transfer, water treatment, detergent products, and fuel transfer. NR Chemical Pump Rage is as follows: Magnetic Drive Centrifugal PumpsMagnetic Turbine PumpsMagnetic Rotary Vane PumpsMechanically Sealed Centrifugal PumpsLiquid Ring Vacuum PumpsVertical Immersion Centrifugal Pumps*Self-priming Mag. Drive Pumps are also available* Our liquid ring pump range is specifically designed for handling toxic and dangerous gases and vapours, there are three different pump types within this range; version NR-VPM is the magnetically driven/sealed version, NR-VPS which is the mechanically sealed close coupled version and the most robust version NR-VPL supplied with a heavy duty coupling arrangement (long coupled pump type). In order to operate successfully all vacuum pumps have to be filled in with a suitable service liquid (usually water or a compatible liquid suitable with the gas being extracted). This allows a constant gas compression for the application and also removes the heat generated during operation of the cycle. Continuous service liquid must be fed to the pump for the vacuum level to be maintained and for the pump to operate efficiently. *Suitable for gases and vapours*The NR-VPL version can be supplied with double mechanical seal and external flushing systemMax. operating temperature: °C Design Features/Benefits • NR-VPM - Magnetically Driven Liquid Ring Vacuum Pump• NR-VPS - Mechanically Sealed Close Coupled Liquid Ring Vacuum Pump• NR-VPL - Mechanically Sealed Long Coupled Liquid Ring Vacuum Pump• Available with automatic drain and anti-cavitation valves• Overhung impeller design• ATEX certified pump• Oil lubricated ball bearings for version VPL only• Low maintenance requirements.• High grade construction materials - AISI 316 / TITANIUM / HASTELLOY C• NEMA motors available upon request Typical Industries/Fluids: • Corrosive, toxic, noxious and carcinogenic gases• Chemical Transfer• Hydrocarbons gases Read more about Side Channel Pumps in our guide
