North Ridge NRM-300EX ATEX Engine Driven Mobile Peristaltic Pump - Sludge Pumps Apllication

NRM-300EX Engine Driven Peristaltic Mobile Pump Flow RateUp to 20 m³/hHead (Pressure)Up to 2 barInlet/Outlet Sizes1 - 4"Temperature Range-20 to 80 °CSolid passageUp to 12 mmMax. Suction LiftAble to Self-prime up to 9 m.w.cTube Materials AvailableNR (Natural rubber), NBR (Nitrile), CSM (Hypalon)Drive optionsPetrol or Diesel engine / Electric / Hydraulic / Pneumatic and Water turbine The peristaltic pump, also called hose pump is part of the positive displacement volumetric pump group, these pumps have a quite simplistic yet extremely robust design which allows them to be used with difficult applications such as transferring high viscosity products and fluids where a high concentration of solids is expected, many of them being applications where other pumps would fail. As one of their popular names indicates the pumping action is done by a combination of a hose located inside the casing of the pump and a rotor with a set of rollers or pads/shoes compressing the hose, by pressing the hose while continually rotating the rollers or pads push the fluid out of the inlet side and onto the discharge side of the hose which means the flow rate achieved is directly proportional to the speed the rollers rotate and squeeze the tube/hose, this action also 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, this together with the ability to run dry indefinitely make the peristaltic pump a suitable option for most pumping applications. Another advantage these pumps have is how easy and cheap they are to maintain as the hose is both the only wearing part in the pump and the only part which is in contact with the fluid, this obviously means the compatibility of the hose is quite important as the wrong material could mean the hose has to be changed quite often increasing the running cost of the pump dramatically, another critical point when selecting a peristaltic pump is to select the running speed correctly, a pump running too quick for a long period of time could also damage the tube/hose therefore it is recommended to keep the running speed as low as possible for applications where a 24 hour operation is required. The NRM-300EX can be supplied with a carrying frame or trolley mounted, this pump range is typically used in construction sites or remote locations where an electric power supply is not available, these pump range can be supplied with either a petrol or diesel engine, electric or pneumatic motor, hydraulic engine and water turbine driven, this pump range is available with ATEX certification hence these peristaltic mobile pump range is ideal for hazardous/non-safe applications where an explosion proof hose pump is required. Hoses are colour coordinated in order to avoid confusions in terms of material compatibility, this also helps the operator to recognise the type of hose required when a replacement is needed, we offer three types of hose materials; natural rubber, Hypalon and nitrile rubber also called buna. colour and materials classification as per below; NR (Natural rubber): YellowNBR (Nitrile rubber): RedCSM (Hypalon): Black Design features & Benefits: • ATEX (explosion proof) pump available upon request.• With integrated vacuum system as standard• Supplied either trolley mounted or with a carrying frame• Sealless - Minimising the risk of leaking.• Efficient - Low power consumption.• Self-priming - Up to 9 metres.• Sheer sensitive - Very gentle on the product being pumped.• Capable of running dry indefinitely - Without the need to install any other device.• Easy to clean as the inner hose is the only part in contact with the product.• 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.
