HTm 8/4-PRO - 2 HP single-phase vertical multistage electric pump
Flow rate up to 200 l/min (12 m³/h). Head up to 62.5 m. 1.5 Kw (2 HP) motor.




The HTm 8/4-PRO centrifugal electric pump from the HT-PRO series by Pedrollo can pump clean water and liquids that are chemically non-aggressive for the components.
It guarantees high performance combined with good reliability, making it an ideal choice in the domestic, civil, agricultural and industrial sectors.
It is particularly recommended for water distribution in conjunction with pressure tanks, for increasing network pressure, for fire-fighting systems and for washing systems and for irrigation.
Pedrollo used AISI 304 and 431 stainless steel to create the HTm 8/4-PRO which guarantees long life and high performance.
The multi-stage stainless steel construction ensures long component life and reduces noise.
