MENCARELLI POMPE E VALVOLE
in die pressed stainless steel since 1945
QUAD series
Stainless steel self-priming pump for high flow rates
Flow rate up to 750 lt/min
Head up to 25 mt
Operating temperature max 110°C
Operating pressure max 4 bar
Motors from 4 HP to 7.5 HP - 2800 RPM
Entirely made of AISI 304/316 high thickness stainless steel
Suitable for aggressive liquids with suspended solids

Self-priming pump

Self-priming pump able to handle liquids with dissolved gases and to operate at a depth of up to 5 metres

Open-type impeller

The open-type impeller is entirely made of stainless steel and is suitable for handling dirty, solid-laden liquids

Small size

The QUAD pump is very compact and, on request, can be supplied with a practical stainless steel carriage for easy transportation

High thickness pump casing

High thickness steel (3mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life

Flammable liquids

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

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

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 QUAD series pumps have the following features:
  • Priming at a depth of up to 5 m with the pump filled
  • Its flow rate makes it suitable for medium/large transfers, whilst keeping a good head
  • Open-type stainless steel impeller, making it suitable for handling dirty liquids
  • Suitable for handling aggressive liquids
  • High thickness steel (3mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life
  • High hydraulic efficiency
  • 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.
