Description
The HT 8/7 multi-impeller centrifugal electric pump by Pedrollo is ideal for use in domestic, civil and agricultural fields.
This electric pump is designed to ensure high performance in a silent way thanks to the 3 stainless steel impellers.
The HT 8/7 stands out for its great silence.
It can also be used for water distribution in conjunction with pressure tanks, for increasing pressure in the network, for fire-fighting systems, for washing systems and for irrigation.
The flow rate ranges from 20 to 200 liters per minute. The head ranges from 40 to 109 meters.
The HT 8/7 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 of AISI 304 stainless steel and cast iron which guarantee the pump compactness but above all resistance and robustness.
With the multi-stage construction, the operating noise is particularly low.
The HT 8/7 must be installed indoors or in any case protected from the elements.
