For High Viscosity Media (Typically 1,000 – 1,000,000 cps)
Our approach to your high viscosity product transfer comes from understanding what is upstream and downstream of your process. Every little detail allow us to advise the suitable pump to use for your application.
If you require higher suction and might run into running dry situation, we have our Air or Electric operated Double diaphragm pump.
If you require higher discharge pressure, we have our circumferential piston pump.
If you require more gentle approach on your solids in your product, we have our twin screw pump as your solution.

Air Operated Diaphragm Pumps
The Tapflo air operated diaphragm pump sanitary series is particularly designed to meet the requirements of the food, beverage, pharmaceutical and cosmetic industries. High suction, Dry running are some of the major features for this pump series.
Made to be clean
Our design allows for total visual inspection of the wetted parts. There are no hidden areas where bacteria can grow. The manifold clamps and the housing screws are simply removed for complete disassembly and cleaning. The pump is also designed for cleaning and sterilization in place – C.I.P. and S.I.P. After such operations, the pump is easily turned in its support for drainage.
Drain the pump by turning the pump in its support
ATEX certified pumps
All sanitary pumps are available in explosion proof ATEX marked version. They are supplied with earth connection and conductive materials; conductive centre section and diaphragms in PTFE (conductive back) or EPDM (conductive).
Typical applications
Industry | Example of application |
Dairy products | Milk, cream, yogurt, cream cheese, melted cheese |
Grossery | Ketchup, mayonnaise, tomato products, mustard |
Beverages | Flavours, colouring, fruit juice |
Bakery | Dough, ingredients |
Brewery | Beer, flavours, colouring, wort |
Hygiene | Soap, toothpaste, schampoo |
Cosmetics | Cream, alcohol, perfume |
Electrically Operated Diaphragm Pumps
The Tapflo electric diaphragm pump is driven by a gear-motor. In this type of pump there is a need to change rotary motion into reciprocating one. It is obtained by an eccentric shaft with a cam and piston. The rotary movement of the shaft (red part) is transferred to the reciprocating movement of the diaphragm shaft (yellow part).

FEATURES & BENEFITS
Low energy cost
Electricity cost < compressed air cost, high efficient (IE3 class) drive
Long diaphragm lifetime
Pneumatic and mechanical support of the diaphragm
Run dry without damage
Easy to use, no need of guarding device
Low spare parts cost
Pump has almost identical design of the wetted side as standard Tapflo air operated diaphragm pump therefore many spare parts are the same
Twin Screw Pumps
GEA Hilge NOVATWIN is the new flexible twin screw pump series in the GEA VARIPUMP line.
The best pump for your application
The GEA Hilge NOVATWIN allows production and cleaning with only one pump by variable speeds up to 3000 rpm. Its self-priming capability of up to 8 meters opens new application fields.
The pump design ensures gentle product handling with almost no pulsation, which makes the pump especially suitable for large and delicate particles.
The system pressure of 30 bar enables also high-pressure applications.
Variable combinations
The pump housing can be equipped with various hardened screw combinations. Reverse flow direction as well as flexible port positions are possible on individual customer demand. This allows the GEA Hilge NOVATWIN to adapt to different applications, media and operating conditions.
Shaft Seals
To accommodate different applications and media, GEA Hilge NOVATWIN are available with single or double mechanical seals.
The mechanical seals are inboard seals placed in the optimum position in the pump to ensure outstanding lubrication and cooling. They also comply with the hygienic design criteria in CIP and SIP processes.
Seal face materials are carefully selected to suit the specific media. Standard materials are silicon carbide /silicon carbide with EPDM elastomers (FDA-compliant).
