1 Experts in water. APPLICATIONS Pumping of clean, non-aggressive liquids, free of fibres in suspension, suitable for applications such as:- Water supply - domestic, rural & industrial Pressure boosting Agriculture & farming Turf water & irrigation Commercial high pressure washing & water treatment Boiler feed VM Series Vertical Multistage Pumps Model Numbers: VM1, VM3, VM5, VM1, VM16, VM3, VM65, VM9 WHY CHOOSE THE VM SERIES MULTISTAGE PUMPS? Vertical multistage centrifugal pump with in line suction and discharge Minimum floor space required and easy to install All hydraulic parts constructed in stainless steel Long service life Corrosion and abrasion resistance High efficiency stainless steel impeller design Low operating costs Less stages required Low maintenance Raised bottom bearing Longer bearing life through reduced risk of damage from sediment Hard faced mechanical seal Longer seal life Teflon neck rings Maintains high efficiency Reduces vibration and noise Reduces sensitivity to thermal expansion Tungsten carbide intermediate bearing/s (selected models) Reduces possible damage from shaft misalignment or vibration Stainless steel threaded companion flanges with gaskets, nuts, bolts & washers included with every pump Easier installation Guaranteed material quality Vertical in-line multistage centrifugal pump with stainless steel hydraulic parts.
