Description
The Pedrollo PV 81 electric pump is recommended for activities such as cooling and air conditioning.
Suitable for industrial use. The use of brass in construction guarantees against rust and oxidation.
It can pump clean water without abrasive particles or liquids that are not aggressive to the constituent materials.
The flow rate ranges from 2 to 17 litres and the head from 6 to 86 litres.
The compact dimensions make the PV 81 simple and easy to install even in tight spaces.
