MENCARELLI POMPE E VALVOLE
in die pressed stainless steel since 1945
CM series
Centrifugal stainless steel monobloc pump
Flow rate up to 1800 lt/min
Head up to 60 mt
Operating temperature max 110°C
Operating pressure max 10 bar
Motors from 2 HP to 10 HP - 1400/2800 RPM
Entirely made of AISI 304/316 high thickness stainless steel
Suitable for aggressive liquids with suspended solids

High thickness pump casing

High thickness steel (4 mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life

Wide range

Over 40 models are available, in order to best meet all requirements and to ensure optimal operating conditions at all times

Standard motors

Motors compliant with IEC 72 UNEL-MEC standards, widely available in all national and international markets

Easy to dismantle

The cleaning and replacement of the mechanical seal and of the impeller are incredibly simple as the pump can be taken apart with ease

Flammable liquids

For handling flammable liquids, explosion proof motors compliant with Atex standards are supplied

Open and closed impellers

Impellers can be closed and open. Open impellers are suitable for handling dirty, solid-laden liquids

Maximum hygiene

The pump casing is internally and externally polished to ensure the highest level of hygiene. In addition, the internal surfaces are smooth and with no sharp edges to provide a high hydraulic efficiency

Greater safety

To ensure a greater safety, the pumps with Atex motors are fitted only with motors certified to operate in more hazardous environments (zone 2 category 2G), although the pump is classified for zone 2 category 3G
The CM series pumps have the following features:
  • 40 different models to meet all requirements
  • Closed or open stainless steel impeller, to handle dirty, solid-laden liquids
  • Suitable for handling aggressive liquids
  • High thickness steel (4 mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life
  • Low number of welds, to ensure higher reliability
  • Very easy to take apart to clean or replace the mechanical seal
  • Motors compliant with IEC 72 UNEL-MEC standards, widely available in all national and international markets should they need to be replaced or repaired
  • Explosion proof motors can be provided to pump flammable liquids
  • Mechanical seal with NBR, FPM or PTFE elastomers

Their resistance to chemical aggressiveness makes them suitable for the chemical, pharmaceutical and textile industries, their capacity to pump dirty liquids makes them suitable for the treatment of waters in general and of industrial waste, while their versatility suits the wine and food industry.

On request, pumps can be supplied on a stainless steel carriage fitted with a switch.

The pumps can also be supplied with DIN 11851, Garolla or Macon fittings.
