AP 80-90

They are suitable for transferring liquids containing impurities up to 2 mm in size.
Their hydraulic components: impeller and feed screw in cast iron, pump body in cast iron/steel allow them to be used with water, emulsions and oily substances in general, with a viscosity not exceeding 21 cSt (3° Engel).
The temperature of the liquid must not exceed 90°C.

They are commonly used on:

- machine tools (milling and turning machines-machining centres)
- glass processing machinery
- surface treatment plants
- filtration systems
They are normally installed on a tank with a capacity which is proportional to their flow rate, about 6-7 cm from the bottom.
It is important to make sure that the maximum liquid level in the tank is always 3-4 cm lower than the support flange (see figure).
Should the liquid be particularly dirty, it is advisable to build a compartment tank in order to allow the sludge to deposit before it is sucked by the pump.
