Immersion Pumps Series AP - with open or close impeller

Usages:
These pumps are suitable for transferring liquids containing impurities measuring up to 2 mm. The hydraulic components, namely the cast-iron impeller and scroll and the steel 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-work centres)
• Glass processing machines
• Surface treatment systems
• Filtration systems

They should usually be installed at about 6 – 7 cm. from the base of a tank, with a capacity in proportion to the flow rate. 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.
