MENCARELLI POMPE E VALVOLE
in die pressed stainless steel since 1945
G/V series
Positive displacement self priming stainless steel pump with flexible impeller and motovariator
Flow rate up to 530 lt/min
Head up to 20 mt
Operating temperature max 70°C
Operating pressure max 3 bar
5.5 HP motor - from 190 to 1000 RPM
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

Mechanical variable speed drive

Using a variable speed drive allows the flow rate to be finely adjusted by changing the RPM of the pump. This also allows to achieve a soft pumping action to handle delicate and highly viscous liquids
The G/V series pumps have the following features:
  • Immediate priming at a depth of up to 5 metres, even when running dry
  • Variable speed drive that allows multiple flow rates to be achieved, making the pumps highly versatile
  • The motor's direction of rotation can be reversed, obtaining a complete flow reversibility
  • Low speed motor, which 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).

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

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