Single-phase centrifugal pump Speroni CFM 550 – power 4000W, pump head 37 m, flow rate 700 l/min.

Centrifugal pump Speroni CFM 550 – single-phase

The Speroni CFM 550 centrifugal pump is a highly efficient monoblock electric pump with a cast iron construction, designed for pumping clean water and other chemically and mechanically non-aggressive liquids.

It is suitable for a wide range of applications in the domestic, agricultural, industrial and installation sectors.

It is used in:

• water supply to buildings and sites;
• irrigation by sprinkling or surface irrigation;
• power supply of hydrophore systems;
• pressure increase in networks;
• other systems requiring the transfer of clean liquids.

The pump housing, motor support and impeller are made of high-quality cast iron, which ensures a long service life and resistance to load.

The rotor shaft is made of AISI 304 stainless steel, guaranteeing high corrosion resistance.

The mechanical seal is composed of ceramic, graphite and NBR, which ensures reliable and long-lasting operation even under intensive use.
