VO 90
They are suitable for transferring liquids containing impurities up to 20 mm in size.
Their hydraulic components: impeller, feed screw, pump body in cast iron 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.
Applications
They are commonly used on:
- machine tools (milling and turning machines-machining centres)
- filtration systems
- surface treatement plants
They are normally installed on a tank with a capacity which is proportional to their flow rate, about 4-5 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.
