TYPE EL - CLASS I
WangenTwin can be used as a product or CIP pump Eliminates the need for a separate centrifugal pump, bypass line, valves, I&C technology
The entire pump casing can be dismantled by screwing off four bolts All parts in contact with the product are then freely accessible
Easy to clean: The WangenTwin pump without casing

Contact-free operation of the feed screws limits wear to the bearings and shaft seal when pumping non-abrasive media Innovative, flexible sealing concept ■ Economic choice of three seal types ■ Seals are available in seal packages or separately ■ Cost-optimised sealing material and design
WangenTwin – highly efficient for a great variety of products and applications
High priming capacity The axial pumping and the low acceleration of the product in the pump allow excellent NPSHR values < 2 m.
■ ■ ■
For emptying tanks With low suction head For pumping viscous products or products with a low boiling point
Reversible pump direction Pumping in both directions by reversing the direction of rotation
■ ■
For pumping and subsequent clearing of the pipe For use as feeding and unloading pump
Large viscosity range Viscosities up to 1.000.000 mPas are possible thanks to the axial pumping and low kneading effect in the product. Good pumping performance thanks to high rotary speeds even with low viscosity products down to 0,5 mPas.
■ ■
For pumping all medium to highly viscous products Various products can be handled with just one pump
60 % gas share possible Thanks to the high rotary speed of the pump, even compressible products can be handled
■ ■
In evaporation plants, e. g. used to produce tomato puree In degassing systems, e. g. used to preserve fruit juices
Typical applications in the food, cosmetics and chemical industries:
Drinks: Freshly squeezed juice, concentrates, mash, pulp, yeast
Milk: Yoghurt, curd cheese, fruit, cheese, pudding, butter
Delicatessen: Ketchup, mayonnaise, mustard, soups, sauces, salads
Confectionary: Pastry, liquid sugar, rework food, fat, fondant, chocolate
Low pulsation The axial pumping and low acceleration in the pump ensure low pulsation. Any pulsation caused by high speeds is quickly relieved.
■ ■
It is possible to extend the discharge line by installing a series of pumps. For applications that require a high dosing precision
Meat: Minced meat, pet food, sausage meat
Can run dry The contact-free operation of the feed screws and a rinsed / blocked mechanical seal make the pump completely insensible to dry running.
■
Pump cannot fail even if the percentage of gas in the line is higher
Cosmetics: Creams, ointments, soap, shampoo
