BI-DIRECTIONAL LIQUID TRANSFER PUMPS - SINGLE PHASE

The ENM series are professional self-priming electric transfer pumps in brass. Equipped with an oversized single-phase asynchronous motor and long-lasting rotary switch, they are designed for heavy applications. These pumps are equipped with a strong suction capacity, they can work even with discontinuous presence of the liquid and the flow is reversible. They are really multifunctional pumps, capable of solving multiple pumping problems. For each application, it is necessary to check the suitability and choose appropriate gaskets.

DISCRIPTION
Tellarini ENM 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. They are also available in three 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.

APPLICATIONS
Agriculture (fungicides, liquid fertilisers, components on agricultural machinery, irrigation)
Professional use (continuous over time and heavy-duty applications, installation on systems)
Industry (installation on plant, machinery, machinery, production lines)

HYDRAULIC SPECIFICATIONS
Gasket on the shaft: Seal
Maximum liquid density 1.1g/cm3 free of hard particles in suspension
Maximum temperature 90°C
Not suitable for aggressive liquids towards pump construction materials and gaskets
Not appropriate for the transfer of petrol, solvents and, in general, in environments with risk of explosion and fire
Possibility of reversing the pumping flow
Coupling with impeller free
Complete with a pair of brass hose fittings for pipes 20 (one straight and one curved)
Possibility of working for short periods with closed pipes
During installation, the pump must be filled with liquid, subsequently this operation is no longer necessary
