Delivery principle of a double-flow HYGHSPIN screw pump from the DOUBLE Flow series

What is a double-flow pump?

The HYGHSPIN DOUBLE FLOW is a so-called double-flow twin screw pump made of stainless steel. Double-flow means that it has two external inlet ports and one central outlet port. A bearing on both sides controls the shaft deflection. The axial thrust caused by the high pressures is compensated internally. The shaft seals are located on the suction side. All in all, despite the high differential pressures, all major components are only subjected to low loads, resulting in high reliability and excellent service life. The parallel use of two stages also makes it possible to pump a large volume flow.

Applications / Industries

Confectionery production

Gentle and consistent processing of chocolate or fruit gum masses.

Baking industry

Twin screw pumps are ideal for gently pumping ingredients such as raw egg, dough, or margarine, especially for dough production.

Meat processing

Hygienic pumping of meat masses and sausage meat for optimum quality with maximum consistency.

Delicatessen production

Soups and sauces in the delicatessen segment are made from select ingredients. Twin screw pumps are used to transport these ingredients gently and hygienically between the individual process stages.

Dairy products

Uniform and gentle pumping of quark, butter, ice cream, or cream.

Pet feed

Hygienic pumping of animal feed ingredients such as meat masses, glycerine, or enzymes.

Pharmaceutical industry

In the pharmaceutical industry, and particularly in the production of components for medicines or infusions, the highest levels of purity and hygiene are required. Hygienic screw pumps are used for pumping enzymes or plutplasma.

Cosmetics applications

Lotions, gels or exfoliating substances present pumps with major challenges. When pumping the solutions, they must not foam up or damage or destroy any components or solids being pumped.

Wine production

Gentle and pulsation-free: gentle conveyance of wine and intermediate products during the must, fermentation, and bottling stages.

Breweries

Whether syrup, yeast, or other components of beverages or raw materials, screw pumps deliver gentle and reliable pumping action and are also hygienic and CIP-compatible.

Bottling of juices

Pumps with particularly gentle conveying properties are required for filling juices, especially when dealing with sensitive, viscous, or chunky products.

HYGHSPIN STANDARD

Screw pump for hygienic applications in the food and pharmaceutical industry Innovative construction, hygienic design, high efficiency, optimum MTTR ratio and more speak for HYGHSPIN.
