Hygienic pumps for the beverage industry
Pump a wide range of media with just one pump?
Whether clear iced tea, thick smoothie bases, fruit pulp, or frozen concentrates – HYGHSPIN screw pumps for the beverage industry operate efficiently across a wide viscosity range. They deliver stable flow rates and constant pressures – even with delicate and sensitive ingredients. This ensures that taste, texture, and product integrity are always maintained. The hygienic design meets the highest requirements of the beverage industry and enables flexible, product-friendly processes with just one pump type – for greater efficiency in production and maximum product safety.
Where can beverage pumps be used?
Beverage pumps are used for a wide range of products. Hygienic stainless steel pumps are used due to the nature of the foodstuffs being pumped. The range of products that can be pumped using beverage pumps is vast. It extends from water-like end products to highly viscous frozen concentrates. Products containing delicate pieces of fruit are pumped, as are media with sensitive cell structures such as yeast. The range of applications is enormous.
In which process stages do beverage pumps perform conveying tasks?
Beverage pumps are required for conveying raw materials and finished products within production facilities for transfer, mixing, and loading processes. Some of them are used in mobile applications on trucks or ships. HYGHSPIN screw pumps are characterized by their outstanding flexibility in the beverage industry. The wide speed range makes it possible to pump both thin juices and highly viscous concentrates effectively and with virtually no pulsation using the same pump. The axial delivery principle and low product speeds in the pump reduce the stress on sensitive media to a minimum.
Can beverage pumps be cleaned hygienically?
In parallel, the HYGHSPIN screw pump can also be used as a CIP transfer pump, which significantly simplifies the plant layout.
Beverage pumps are often used in batch processes. Fast operation is advantageous for transfer and loading processes in tank farms. This requires high volume flows. At the same time, however, the NPSH values of the beverage pump used must always be taken into account. These are often the limiting factor in the entire process. Increasing volume flows increase the pressure losses in the suction line, causing the NPSH value of the system to drop. If the critical value specified by the beverage pump used is reached, a further increase in volume flow is no longer possible because the pump cavitates and becomes damaged. HYGHSPIN screw pumps are characterized by particularly low NPSH values and high suction capacity. In many cases, replacing the existing beverage pumps with HYGHSPIN screw pumps has significantly increased the capacity of the existing system without further adjustments. This has resulted in considerable savings in operating costs.
Are beverage pumps self-priming?
HYGHSPIN screw pumps are self-priming when operated correctly in conjunction with an appropriate system layout. Self-priming beverage pumps are required, for example, when smaller containers of raw materials need to be emptied. Shaft seals must be selected with care for beverage pumps. Many products have a significant sugar content. This poses a risk of the sliding surfaces of the mechanical seals sticking in beverage pumps. Torque transmission during the start-up process poses a risk of the stationary part of the seal breaking out and the mechanical seal failing.
Which seals are best suited for beverage pumps?
Mechanical seals with reduced sliding surfaces in a knife-edge design have proven themselves for beverage pumps. As a result of the reduced surfaces, the transmissible torque and the risk of failure are greatly reduced. Alternatively, pumps with self-lubricating lip seals can be used. Since these allow the pump to run dry without flushing the shaft seal, lip seals are particularly advantageous for mobile pump units.
