MENCARELLI POMPE E VALVOLE
in die pressed stainless steel since 1945
G/N series
Positive displacement self priming stainless steel pump with flexible impeller for direct connection to power take-offs
Flow rate up to 570 lt/min
Head up to 25 mt
Operating temperature max 70°C
Operating pressure max 3 bar
AISI 304 high thickness stainless steel pump casing and synthetic rubber impeller
Suitable for viscous liquids with suspended solids

Self-priming pump

The special design of the pump casing ensures an immediate suction, even when running dry, up to a depth of 5/6 metres

Delicate pumping action

The low speed motor ensures a gentle pumping action for delicate liquids, and a continuous and regular flow

Suitable for viscous liquids

The shape of the impeller allows the pump to handle viscous fluids with suspended solids

High thickness pump casing

High thickness steel (3/4mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life

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

Flow reversibility

The direction of rotation of the motor can be reversed to ensure a total flow reversibility, with identical performance for both directions of rotation

Pump casing formed as a single piece

All pump casings are constructed from high thickness stainless steel sheet metal, which ensures quality and long life. The pump casings undergo continuous quality controls of the welds and are internally and externally polished to ensure the highest level of hygiene

Impeller made of non-toxic rubber

The impeller is made of synthetic rubber (Neoprene or EPDM) and is entirely non-toxic and resistant to several acids. The Neoprene impeller complies with the American FDA regulations related to the handling of food grade liquids

Direct connection to power take-offs

The G/N series pumps are specifically designed to be directly connected to power take-offs, such as those of tankers or tractors
The G/N series pumps have the following features:
  • Immediate priming at a depth of up to 5 metres, even when running dry
  • Flow reversibility
  • If used at low RPM, it ensures a gentle pumping action for delicate liquids
  • Continuous and regular pumping action
  • Capacity to handle viscous and solid-laden liquids
  • High thickness steel (3/4mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life
  • Monobloc pump casing casting for higher strength and a better seal
  • The cleaning and replacement of the mechanical seal and of the impeller are incredibly simple as the pump can be taken apart with ease
  • Flexible impeller made of entirely non-toxic synthetic rubber (Neoprene or EPDM) and resistant to different acids
  • Mechanical seal made of NBR-graphite or NBR-tungsten carbide

These features make these pumps exceptionally versatile. They can be used in the chemical-pharmaceutical industry (starch, wax, water-based glues, creams, cleaners, glycerine, glycols, latex, vegetable and animal fats, liquid soaps, syrups, shampoos, industrial water treatment, paints) and in the wine-food industry (beer, butter, melted cheese, glucose, milk and condensed milk, jam, honey, must, oil, cream, tomato sauce, fruit juices, eggs, yogurt, wine, destemmed grapes, liquid sugar).

The pump is supplied with a cast iron base for easy connection to power take-offs.

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

The recommended highest RPM is 900 RPM (700 RPM for G/200/N and G/200.1/N).
