Pigging System

Fields of applications
Process systems, which can be cleaned with pigs, are becoming increasingly important for the low-germ processes in the food industry. Among other reasons, this is attributable to an increased environmental consciousness, costly waste water treatment, prevention of costly product losses, and production streamlining measures.
We offer a variety of pigging technologies to satisfy the requirements of the wide range of processes.
Optimum pigging geometry and the suitable process (e.g. single pigging, dual or tandem pigging) depend on different process factors and are therefore always designed to the specific project.

There are two basic system:

• DMV Pigging System (dynamic system for particularly low-germ processes and highly viscous media)

Features

• Close and sterile pipe system with CIP/SIP- LIAG® arc- and pigging valves (EHEDG certified)
• No dead pockets
• Can be completely dismantled even when welded in place
• Number of thread and clamp unions can be minimized
• Very few different spares needed due to uniform modular system for all components
• Safe separation of products – no mixed phases
• Reduction of product loss and time consuming drain-of
• Optimized cleaning result by use of dynamic lip pigs – absolutely tight - practically no wear
• 90° standard bows (1.5 x D) can be cleaned with pig
• The pig can be cleaned in the closed system without removing it
• The DMV system is suited for one or more pigs in the same system and can be completely automated
• All components comply with 3A (FDA) sanitary standards
• Available in 1 ½" – 4" / DN 40 – DN 100
• DMV systems are particularly serviceable for low-germ processes and high viscous/pasty products, such as yoghurt, dressings, softcheese, chocolate, etc
