Repair service We repair ViscoTwin pumps on site at the customer‘s premises or in our Shop in California.

Sanitary – Efficient – Powerful ViscoTwin – 100 % Reliable ViscoTwin Pumps are manufactured by Pumpenfabrik Wangen in Germany. It is designed to be the next Generation of Positive isplacement Pumps that fulfills the most stringent requirements for sanitary Applications. ViscoTwin Pumps greatly improve the current status quo on wear and tear caused by abrasive media, CIP’ability, very low suction head requirements, the viscosity range it can pump against high pressures, and ease for inspection and maintenance. The design is new from the ground up. ViscoTwin pumps are 100% bi-directional without restriction. 4 bearings are paired, 2 for each direction. The 2-part housing enables a larger top port and is 100% drainable after CIP/SIP.

Without special pre-caution, it can handle up to 266°F for Operation and SIP. Non-proprietary ORings in FPM for static seals insure low cost of owners hip by design. Various options are available for Process Connections, Screw Pitches, Bearing Frame Materials, rotating Shaft sealing designs, heated Housings, and Materials on wetted Parts.

Exploded view of the ViscoTwin pump

The ViscoTwin screw pump is part of Wangen’s sanitary pump solutions. It was developed to reliably pump low and high viscous products with stringent sanitary requirements. It also pumps highly volatile or gaseous products.

Best results for SIP and CIP cleaning •

Best results for SIP and CIP cleaning

•

The very high rotational speed range allows to optimally pump product or cleaning liquid

•

High rotational speed in cleaning mode ensure perfect pump cleaning

•

Capability to achieve discharge pressures on water up to 230psi ensure effective

•

product push-out‘s at the end of run

Pumping and cleaning with one pump: ViscoTwin 130

Two pumps in one • • •

The ViscoTwin can be used as a product or CIP ump. It eliminates the need for a separate centrifugal ump, bypass line, valves, and controls technology

Easy manual cleaning

Low servicing costs

• •

Contact free operation of the Rotors limits the wear on bearings and shaft seals when pumping non-abrasive media Innovative and flexible sealing concept - Economic choice of 3 mechanical sealing arrangements - Spares are available individually or in packages - Cost optimised sealing design with non-proprietary O-Rings

Easy cleanable: The ViscoTwin pump without housing

ViscoTwin – highly efficient for a great variety of products and applications Typical applications in the food, cosmetics and chemical industries:

High priming capacity The axial flow direction and the low media acceleration in the pump allow for excellent NPSHR values < 4 feet.

• •

For emptying tanks at low hydrostatic head pressure For pumping viscous products or products with a low boiling point

Juices: Freshly squeezed juice, concentrates, mash, pulp, yeas

Reversible pump direction Pumping in both directions by reversing the rotation direction.

• •

For pumping and pipe emptying at the end of run (pigging) For use as supply and discharge pump

Milk: Yoghurt, curd cheese, fruit, cheese, pudding, butter

Large viscosity range Viscosities up to 1.000.000 mPas because of the axial flow direction with a low kneading effect through the pump. Excellent pumping performance with low viscosity products to 0,5 mPas because of high rotation speeds.

• • •

For pumping highly viscous products Various products can be conveyed with just one pump

Sauces and Toppings: Ketchup, mayonnaise, mustard, soups, sauces, salads

60 % gas share possible Because of the high rotation speed of the Rotors, compressible products can be pumped as well.

• •

In evaporation systems for tomato paste In de-aeration systems for fruit juices

Confectionary: Pastry, liquid sugar, rework food, fat, fondant, chocolate

Very low pulsation The axial pumping and low acceleration in the pump ensure low pulsation. Any pulsation caused by high speeds is quickly released.

• • •

ViscoTwin Pumps can be installed in series. For applications that require a high dosing pr ecision

Meat: Minced meat, pet food, sausage meat

Dry running The contact-free operation of the rotors with a dual mechanical seal enable the pump to run dry.

•

The Pump cannot fail even if the %-ige on gas in the line is higher

Cosmetics: Creams, ointments, soap, shampoo

Special features • • • • •

Materials in contact with the product in stainless steel 316L Product wetted surfaces: Ra < 0,8 μm CIP (Cleaning in Place) and SIP (Sterilisation in Place) cleaning Elastomers comply with FDA and EC1935 / 2004 Designed according to 3A and EHEDG guidelines

Services offered for your Pump Application Customer service starts well before the Pump is delivered: Each Application is unique and deserves professional attention for the sizing of pump head, rotors, shaft seals, the selection of the motor, and other available options. When the pump is assembled it is tested on the test stand and undergoes a functional and leakage test.

Processtec, Inc 933 W. Hemlock Ave Visalia CA, 93277 USA

Test Pumps From each size we have Test pumps available that we can commission for your specific Application. Cross-industry consulting, new developments and solutions We are interested to help you find the best solution for your pumping tasks, with difficult media at various viscosities and propoerties. Commissioning and Training We offer professional support for the correct pump installation via remote support or on site. If you feel more comfortable with on site training on how to inspect and maintain the pump, we offer that as well.
