Valisi non-metallic series

Valisi non-metallic series

Despite their simple design and operating principle, Valisi plastic diaphragm pumps are characterised by exceptional performance and reliability. They can be used to pump clean liquids with low viscosity as well as abrasive liquids with medium viscosity. In addition, these pumps can handle large particles without damaging the equipment. And thanks to the pneumatic motor, they can be used in explosive atmospheres.

Hygienic Series

Hygienic Series

Pneumatic diaphragm pumps of the hygienic series are made of polished stainless steel AISI 316L. The pumps are hermetically sealed, self-priming, and are designed primarily for pumping of slightly aggressive media, food and cosmetic products. They are used in those industries where there are increased requirements to hygiene, for example dairy production.

Flow Range:max. 850 l/min
Temperature:up to 120°C
Pressure:8 bar
Solids:max. 15 mm
Materials:AISI 316 L
Hygienic Progressive Cavity Pump

Hygienic Progressive Cavity Pump

The hygienic screw pumps are specially designed for use in the food, cosmetics and beverage industries. The pumps have a simple design, which greatly simplifies their cleaning. All metal parts in contact with the pumped product are made of SS304 / SS316 stainless steel. For the transport of materials with high viscosity, pumps with a wide discharge hopper are designed.

Flow Range:max. 86 m3/h
Viscosity:5.000 St
Temperature:max. +150 °C
Pressure:max. 24 bar
Solids:presence of solid particles up to 7%
Materials:stainless steel
Hopper pumps

Hopper pumps

The design of the pumps allows them to be used for many different applications. The standard design includes an enlarged rectangular inlet hopper with a screw conveyor that pushes the product to be pumped into the pump's working section. There are versions in which the pump inlet is equipped with a large screw, an integrated cork breaker or both. Most pumps are supplied in a monoblock design (direct connection of the pump to the electric motor) or with a free shaft outlet (without an electric motor).

Flow Range:up to 200 m3/h
Viscosity:up to 3.000.000 cSt
Pressure:up to 36 bar
Solids:presence of particles up to 40%
Materials:steel, cast stainless steel
Flexible impeller pumps

Flexible impeller pumps

The MENC-INOX industrial pumps are pumps with a flexible stainless steel impeller. The impeller deforms inside the stainless steel casing to provide fast suction of up to 5 m and constant and accurate liquid transfer. In addition, the low speed makes this pump suitable for pumping liquids and media containing solids that require careful handling. Due to the low speed, pumping is carried out without harmful foaming of the emulsion, the so-called "shear effect".

Flow Range:up to 930 lt/min
Temperature:max 70°C
Pressure:max 3 bar
Materials:stainless steel
Head:up to 35 mt
Stainless steel centrifugal monoblock pumps

Stainless steel centrifugal monoblock pumps

ASCO PUMPS offers industrial pumps for the food, cosmetics, pharmaceutical, petrochemical and electroplating industries. All products are manufactured using advanced technologies by cold pressing. This production method allows the pumps to operate in difficult conditions, with an extended and guaranteed service life. The main distinguishing feature of the products is that thicker sheets of 4 mm thick AISI 304/316 stainless steel are used in the production process. This guarantees a long service life of the pumping units. Another important factor is that the corrosion resistance of parts made of stainless steel obtained by cold pressing from rolled products has been significantly increased.

Flow Range:up to 1800 lt/min
Temperature:max 110°C
Pressure:max 10 bar
Materials:AISI 304/316 high thickness stainless steel
Head:up to 60 mt
Rotary lobe pump DW

Rotary lobe pump DW

The DW pump series is the newest series of SPX FLOW rotary lobe pumps. No other cam pump on the market today offers such a wide range of functions in one pump. DW pump models are hygienic and meet all the requirements of industrial standards 3-A and EHEDG. All parts in contact with the product are made of AISI 316L stainless steel and the elastomers meet FDA requirements.

Flow Range:3 - 1,016 litres/100 revs
Viscosity:max. 100000 mPas
Temperature:210 ºC
Pressure:0 - 30 bar
Materials:AISI 316L stainless steel
Rotary lobe pump R

Rotary lobe pump R

The R-series pump is ideal for the type of application where pumps with metal rotors will not work effectively. When you need to strip clean your pump because the product will not wash out by using a normal CIP process such as meat processing, the R pump overcomes this problem by its simple robust design. The R pump design utilities a floating rotor without rotor nuts. Rotors are interchangeable and can only be fitted in one position due to a specially modified square shaft.

Flow Range:up to 54 m³/h
Pressure:6.8 - 10 bar
GUTH RA - portable agitators lateral for wineries

GUTH RA - portable agitators lateral for wineries

GUTH RA portable agitators are used for mixing, stirring and homogenising water-like or medium viscosity products. They are most commonly used in wine cellars for the production of wine and sparkling wines, but are also used in other food industries where gentle and efficient mixing is required.

The classic characteristics of RA series stirrers are their durability and efficiency. They are an important partner in the wine industry worldwide thanks to their first-class mixing results. GUTH RA portable stirrer is an unbeatable, long-term solution for any mixing problem.
