Foaming is a common problem with many cleaning products, shampoos and shower gels. As the foam overflows and leaks out, the outer surface of the bottle is smeared with product residue, which causes problems when applying labels. To eliminate this problem, the filling machine should be operated relatively slowly to prevent foaming, or the outside of the bottle should be cleaned after filling. Foaming can also be avoided by using a suitable pump system, which will greatly simplify the filling process.
A large number of pumps used in systems cause intensive mixing of the product, which contributes to undesirable foaming. However, this can be avoided by using hygienic HYGHSPIN twin screw pumps in your system, as they pump the product more gently.
An international detergent manufacturer was experiencing foaming issues during the filling of their products. By deploying HYGHSPIN twin screw pumps, they increased the filling capacity of their lines from 90 to 160 bottles per minute, which shows a high return on investment.
The design of the HYGHSPIN twin screw pump from Jung Process Systems GmbH is based on the principles of hygienic design. Typically, pumps of this type, including the HYGHSPIN, are made of stainless steel. Nevertheless, all parts that come into contact with the product are made of hard materials. There is no risk of damage such as scratches or holes that can occur with cast iron pumps. All surfaces are electropolished and have a standard roughness of less than 0.8 µm. Versions with a Ra value of less than 0.4 µm are also available for special customer requirements.
The HYGHSPIN twin screw pump can pump products with a wide range of viscosities. Not only does this make them highly customisable and flexible to requirements, but also the fact that they can be cleaned without being removed from the system. The non-contact cleaning takes place inside the system, which does not need to be disassembled, and this offers an advantage when pumping paints, varnishes and adhesives. Risks associated with excess product are eliminated. The HYGHSPIN twin screw pumps are also available in a solvent-resistant version and a version suitable for use in potentially explosive atmospheres. Thanks to the excellent thermal separation between the pump casing and the bracket bearing, the pumps are also suitable for pumping high temperature products without additional cooling.
