MENCARELLI POMPE E VALVOLE
in die pressed stainless steel since 1945
GIGAPAS series
Liquid-ring self priming stainless steel pump for delicate or aggressive fluids
Flow rate up to 435 lt/min
Head up to 40 mt
Operating temperature max 110°C
Operating pressure max 7 bar
Motors from 2 HP to 7.5 HP - 700/900/1400 RPM
Entirely made of AISI 304/316 high thickness stainless steel
Suitable for aggressive liquids

Self-priming pump

Liquid-ring self priming pump able to handle liquids with dissolved gases and to operate at a depth of up to 6 metres

Reduced speed

The low speed motor ensures a gentle pumping action for delicate or viscous liquids

High hydraulic head

The high efficiency of the pump allows high hydraulic heads to be achieved despite the use of low speed motors

High thickness pump casing

High thickness steel (4mm) 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

Flow reversibility

On request, a motor that can reverse its direction of rotation is supplied, to ensure full flow reversibility

Stainless steel impeller

The impeller is made from microcasting of AISI 304 or 316 stainless steel. Its shape has been optimised to ensure a high hydraulic efficiency

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 GIGAPAS series pumps have the following features:
  • Priming at a depth of up to 6 m with the pump filled
  • Flow reversibility
  • Suitable for handling aggressive liquids
  • The low speed motor ensures a gentle pumping action for delicate or viscous liquids
  • High thickness steel (4 mm) 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
  • Microcast impeller from AISI 304/306 stainless steel
  • Mechanical seal with NBR, FPM or PTFE elastomers

Their resistance to chemical aggression makes them suitable for the chemical, pharmaceutical and textile industry, while their versatility makes them suitable for the wine-food industry.

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

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