MPC Immersion Pumps

The pumps are suitable to transfer liquids containing impurities measuring up to 2 mm. The hydraulic components, namely the brass impeller and the aluminium scroll and 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:
Machine tools (milling machines – lathes - drills)
Filtration 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.
