Use and maintenance manual

ENT series are professional versions of self-priming brass transfer pumps. Equipped with an oversized three-phase asynchronous motor and long life rotary switch, they are designed for heavy duty applications.
These pumps are equipped with a strong suction capacity, can operate even with discontinuous presence of the liquid and you can reverse the flow. They are really multifunction pumps, able to solve multiple pumping problems. For each application it is necessary to verify the suitability and choose the appropriate gaskets.

The product are particularly suitable for use:

agriculture (fungicides, liquid fertilizers, 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

Maximum capacity : 250 lt/min
Maximum head : 29 m
Gasket on the shaft: Seal
Maximum priming height : 6 m
Threaded ports: 2"
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 (see technical specifications)
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 locked
Complete with a pair of brass hose fittings for pipes 50 (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
