HT 3/9-PRO - 4 HP three-phase vertical multistage electric pump
Flow rate up to 90 l/min (5.4 m³/h). Head up to 146 m. 3 Kw (4 HP) motor.
The Pedrollo HT 3/9-PRO centrifugal electric pump is designed to guarantee excellent performance and solid construction despite its compact size.
Made entirely of stainless steel, the pump is robust and resistant.
The HT 3/9-PRO is made with a special multi-stage construction, the operating noise is particularly low.
Recommended for pumping clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
Ideal for civil, agricultural and industrial sectors. In particular, the HT 3/9-PRO is suitable for water distribution in combination with pressure tanks, for increasing pressure in the network, for fire-fighting systems, for washing systems and for irrigation.
It must be powered by a three-phase voltage, has a horsepower of 4 HP and the temperature of the liquid to be pumped ranges from -15 degrees centigrade up to 90.
The flow rate ranges from 5 to 90 metres and the head from 78 to 146 litres.
