Tellarini ENM Bi-directional Liquid Transfer Pumps are self-priming and have bronze bodies and single impellers. They have 316 stainless steel shafts, fitted with carbon ceramic and NBR mechanical seals. (Viton® is available at extra cost). The IP44 motors have a forward and reverse switch for filling and emptying duties. ENM pumps are also available in 3 phase as ENT pumps. They are designed mainly for pumping clean liquids at temperatures up to a maximum of 90ºC, but can also handle very small soft solids, in suspension. Maximum recommended suction lift, with a foot valve, is 6 metres. These are good, general-purpose, portable pumps for circulating and transfer of water, sea-water, juices, gas oil (“red diesel”), bio-fuel, transformer oil and mild chemicals. However, THEY MUST NOT PUMP DERV (“white diesel”), petrol, solvents or products with a low flash point. All models are supplied free-standing, so for ease of handling and added protection, a full frame is a worthy investment as an optional extra.
