HT 10/7 - 4 HP three-phase vertical multistage electric pump
Flow rate up to 250 l/min (12 m³/h). Head up to 108 m. 3 Kw (4 HP) motor.
The Pedrollo HT 10/7 multi-impeller centrifugal electric pump is ideal for pumping clean water and liquids that are chemically non-aggressive for the materials from which the pump is made.
This electric pump is designed to guarantee high performance despite being compact.
Its silence makes the HT 10/7 ideal for applications in the domestic, civil and agricultural fields, in particular for the distribution of water in combination with pressure tanks, for increasing pressure in the network, for fire-fighting systems, for washing systems and for irrigation.
The flow rate ranges from 30 to 250 liters per minute. The head ranges from 30 to 108 meters.
The HT 10/7 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 pump is made with a mix of steel and cast iron which ensures that the pump has excellent strength and resistance.
With the multi-stage construction, the operating noise is particularly low.
The HT 10/7 must be installed indoors or in any case protected from the elements.
