Product Recovery Systems
Aseptic Pigging System
An aseptic pigging system allows to recover cost intensive products out of product lines. Powered by compressed sterile air, the pig pushes the product out of the pipe. The remaining product film on the inside of the product line can then be removed with the CIP. This technology significantly reduces the strain on the waste water and lowers cleaning costs, for example water and detergents costs.
The shafts for the pig holder and the pig actuator are hermetically sealed with welded metal bellows. The connection of the body and the pig actuator is done with a service friendly 3-part massiv clamp. The body is made of stainless steel 1.4435 (AISI316L) and is ground inside and polished outside. The connections are normally welding connections according to DlN 11850, on request they can be imperial or ISO welding connections, dairy screw connections, clamp connections or aseptic flanges according to DIN 11864-2. Parts in contact with the product are completely made out of 1.4435 (AISI316L) with silicon seals between the inside and the outside. The pigging system can be delivered in sizes DN40 to DN100.
