The Pedrollo CP 180-ST6 is a 1.1 kW (1.5 HP) stainless steel centrifugal pump on a 400 V three-phase supply, delivering up to 230 l/min and 30 m head. It shares its hydraulics with the cast iron CP but is built for water that would corrode cast iron.

Pump body, impeller and shaft are all stainless steel, so it suits softened, treated and slightly aggressive water, and applications where hygiene matters.

Full Description

Product overview

The Pedrollo CP 180-ST6 is a 1.1 kW (1.5 HP) single-impeller centrifugal pump on a 400 V three-phase supply, covering 40 to 230 l/min with a working head of 30 m down to 13 m. It is the stainless steel version of the CP 180: the same performance, but with pump body, impeller and shaft in stainless steel instead of cast iron.

Use it where a cast iron pump would corrode or contaminate the water: softened or treated water, rainwater and greywater reuse, food and drink premises, and light industrial process water. The ST4 grade is AISI 304 stainless; the ST6 grade is AISI 316L for water with a higher chloride content.

Key features

All-stainless wetted parts

Pump body, impeller and shaft in stainless steel. No cast iron in contact with the water.

Two grades

ST4 in AISI 304 for clean and softened water; ST6 in AISI 316L for more aggressive liquids.

CP hydraulics

Same duties as the matching cast iron CP, so it slots into existing CP applications.

Up to 10 bar

6 bar working pressure on the 100–158 sizes, 10 bar on the 170–200.

Single or three-phase

CPm single-phase 230 V with thermal protection, or CP three-phase 400 V with IE2/IE3 motors.

Continuous duty

Rated S1 for continuous running.

Typical applications

Softened and treated water

Downstream of softeners, RO plant and treatment where cast iron would corrode.

Rainwater and greywater

Reuse systems in homes and commercial buildings.

Food and drink

Process and wash-down water where hygiene matters.

Light industrial process

Cooling, transfer and pressure duties with slightly aggressive water.

Frequently asked questions

What is the difference between ST4 and ST6?

ST4 pumps are made in AISI 304 stainless steel and suit clean and softened water. ST6 pumps are made in AISI 316L, which resists chlorides better, so they suit brackish, treated or more aggressive water. The pump performance is identical.

How does it compare with the cast iron CP?

The hydraulics are the same, so a CP-ST gives the same flow and head as the matching CP. The difference is the materials: stainless steel throughout instead of cast iron body and shaft.

Is it self-priming?

No. It needs a flooded suction or a foot valve on the suction line. For suction lift from a tank or well below the pump, look at the Pedrollo FUTURE JET-ST stainless self-priming range.

What is the maximum working pressure?

6 bar on the CP 100, 130, 132, 150 and 158 sizes, and 10 bar on the CP 170, 180, 190 and 200.
