HT 3/7-PRO - 2.5 HP three-phase vertical multistage electric pump
Flow rate up to 90 l/min (5.4 m³/h). Head up to 113 m. Motor 1.8 Kw (2.5 HP).
The Pedrollo HT 3/7-PRO vertical multi-impeller centrifugal electric pump is recommended for pumping clean water and liquids that are not chemically aggressive for the materials from which the pump is made. It differs from the basic series in having a cast iron pump body.
It has a flow rate that varies from 5 to 90 litres per minute with a head of 61 to 113 metres.
The high efficiency and adaptability to the most varied applications, even anomalous ones, make it an ideal choice in the domestic, civil and industrial sectors; in particular for the distribution of water in combination with autoclave tanks, increasing the pressure in the network.
Installation must be carried out indoors or in any case protected from the elements.
