HTm 3/7 - 2.5 HP single-phase vertical multistage electric pump
Flow rate up to 90 l/min (5.4 m³/h). Head up to 113 m. 1.8 Kw (2.5 HP) motor.




The HTm 3/7 centrifugal electric pump from the HT series by Pedrollo guarantees high hydraulic performance combined with excellent hydraulic construction.
The jacket, impellers and diffusers are made of AISI 304 stainless steel and the crankshaft is made of 431 stainless steel which guarantees long life and high efficiency.
It can pump clean water and chemically non-aggressive liquids for the components.
The HTm 3/7 stands out for its high performance and adaptability which make it an ideal choice in the domestic, civil, agricultural and industrial sectors.
Particularly for water distribution in conjunction with pressure tanks, for increasing network pressure, for fire-fighting systems, for washing and irrigation systems.
