MENC-INOX series
Positive displacement self priming stainless steel pump with flexible impeller and IEC 72 UNEL-MEC motors
The MENC-INOX series pumps have the following features:
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 carriage fitted with a rotation direction inverter.
The pumps can also be supplied with DIN 11851, Garolla or Macon fittings.
Positive displacement self priming stainless steel pump with flexible impeller and IEC 72 UNEL-MEC motors

Flow rate up to 930 lt/min
Head up to 35 mt
Operating temperature max 70°C
Operating pressure max 3 bar
Motors from 0.34 HP to 6 HP – 570 ÷ 1400 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 metresDelicate pumping action
The low speed motor ensures a gentle pumping action for delicate liquids, and a continuous and regular flowFlow 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
High thickness pump casing
High thickness steel (3/4mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer lifeEasy 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 easeStandard motors
Motors compliant with IEC 72 UNEL-MEC standards, widely available in all national and international marketsPump 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 liquidsMechanical gear unit
For the MENC-INOX 40 and 50 series a mechanical gear unit is available, which allows to achieve a pump rotation speed of only 570 RPM for a very gentle pumping action and for highly viscous liquids
- Immediate priming at a depth of up to 5 metres, even when running dry
- Flow reversibility
- Motors compliant with IEC 72 UNEL-MEC standards, widely available in all national and international markets should they need to be replaced or repaired
- Low speed motor, which ensures a gentle pumping action for delicate liquids
- Capacity to handle viscous and solid-laden liquids
- 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
- Continuous and regular pumping action
