Type IMM 71
Usages:
The pumps are suitable to transfer liquids containing impurities measuring up to 2-3 mm.The
hydraulic components, namely the brass impeller, the scroll and the aluminium pump body allow
the pumps to be used with water, emulsions and oily substances in general with a maximum
viscosity of 3° Engler (21 CST).
The temperature of the liquid must not exceed 90° C.
They are usually used on:
Glass processing machines (TRI version) Surface treatment systems (version in cast iron)* Filtration systems Air-conditioning systems.
They should usually be installed on a tank, with a capacity in proportion to the flow rate, at about 4 - 5 cm. from the bottom. It is important to check that the maximum level of the liquid in the tank always remains 3 - 4 cm. lower than the flange (see figure).
In cases where the liquid is particularly dirty, the user is recommended to construct the tank in compartments to allow the dirt to deposit before it is stirred up by the pump. For other usages you are advised to consult our technical office.
