Process systems which can be cleaned with pigs are becoming increasingly important for low-germ processes. Among other reasons, this is attributable to an increased environmental consciousness, costly waste water treatment, prevention of costly product losses, and production streamlining measures.

  • Minimum product loss
  • Safe separation of product – no mixed phases
  • Increase of product quality
  • Reduction of time-consuming cleaning and waste water
  • Environmentally sound

Sterile processes pose stringent hygienic demands on system components. For low-germ processes we offer DMV pigging systems featuring EHEDG certified and, optionally, 3-A rated CIP/SIP LIAG® arc valves and pigging valves and specifically designed pig launching and receiving stations without dead pockets. By virtue of the modular component design, thread and clamp unions are virtually no longer needed. Typical hygienic risk areas are thus minimized from the very start. All valves, even when welded in place, can be taken apart and easily converted. The product is pushed out with a dynamic 2-seal lip pig designed for the DMV pigging system.

Features DMV Pigging System

  • Closed and sterile pipe system with CIP/SIP LIAG® arc and pigging valves without dead pockets
  • Optimized cleaning result by use of dynamic lip pigs
  • 90° standard bends (R = 1,5 x D) can be passed without any problem
  • The pig can be cleaned in the closed system without removing it
  • DMV pigging systems are optimally suited for low-germ processes and high viscous, fast hardening media, e.g. yoghurt, dressings, soft cheese, chocolate, toothpaste etc.
