Hygienic-Sanitary Pumps

Hygienic-Sanitary Pumps Applications

Whether you are handling food, beverages, cosmetics, pharmaceuticals or biotech products the fundamentals are very basic – the process equipment shall not contaminate the handled product and it shall be cleanable in desired way. So how will you be able to determine if your equipment such as pumps is safe and fulfills your requirements? A number of standards and directives for hygienic equipment are applicable. In this brochure, you will learn more about them and how we have incorporated them in our hygienic product range. The chart on the next pages gives you a brief introduction to applicable directives, norms and regulations and how they are incorporated in our pump range.

Integrated into your plant

Clean water

Clean water or so-called deionized water (clean water free from carbon molecules) is used widely in food and pharmaceutical processing plants. Extremely important here is using 316L (low carbon) steel. Use of normal 316 will cause “picking” inside the pump when carbon molecules are “stolen back” by the deionized water. This will turn deionized water to normal water, the process will fail and also the pump will be destroyed. The solution is using the Tapflo CTH centrifugal pumps that always come with 316L wetted materials and optionally sintered (pure) silicon carbide seals.

CIP cleaning

CIP cleaning (Clean In Place) is an automatic cleaning system where the pipe system with its pumps, valves and other equipment is flushed with a cleaning liquid, all while the system is assembled. To obtain sufficient cleanliness, the CIP flow speed in the system is minimum 1.5 to 2.0 m/s, relatively low back pressure up to 1 bar is required. Tapflo CTH range is commonly used as CIP pump for pipe systems from ¾” up to 4” (DN 15 up to DN 100). For the concentrated cleaning chemicals, small sized 3/8” or ½” plastic diaphragm pumps are typically used.

SIP cleaning

SIP cleaning, Sterilize In Place is widely used in pharmaceutical industry, but becomes more and more popular also in food and beverage industries. Two methods are used for SIP, either the classic steam injection where basically no pumps are required or liquid sterilization in closed pressurized (2 bar) system. This second method saves process equipment like pumps from dry running, saving costs and life of mechanical seals etc.

 

Handling liquids in hygienic industries

In your production plant there are numerous of pump applications. The main focus is probably on the pumps used for the ready products and clean water, however, there are also just as many needs of pumps for ingredients, additives and auxiliary applications like detergents, chemicals, and solvents. Whichever part of your process, we will provide the suitable pump solution.

Moving the product

The applications mentioned above are keystones in almost all food, beverage and pharmaceutical processes. However pumping the ready product is usually the greatest challenge. The first challenge is that the nature of the product might be demanding for process equipment like pumps; high viscosity, big solids or abrasive ingredients. The second challenge is that the product shall maintain its shape and nature after the process, without any destroying of solids, shearing or contamination. For these types of duties, a cleanable pump design, selection of materials and traceability are crucial. CTH centrifugal pumps, sanitary and EHEDG diaphragms pumps and PT/PTL hose pumps are used.
