DMV and SMV Pigging Systems

There are two types of Pigging systems DMV for low germ processes and SMV for insensitive media. The DMV pigging system includes EHEDG-certified and 3-A rated CIP/SIP free flow shutter valves and specifically designed pig launching and receiving stations without dead pockets. There are a range of operating options including one way, single loop, two way, double loop and a ring system to suit every environment. Simplifying the modular component design, thread and clamp unions are virtually no longer needed, minimizing typical hygienic risk areas by design. All shutter valves, even when welded in place, can be easily disassembled for maintenance.

The DMV pigging System works with a 2-seal lip pig and are of homogenous hygienic design. They offer excellent cleaning effect and are virtually free of wear. The pigs are highly flexible and can pass tight radíi (R= 1.5 x D). Dynamic lip pigs are optionally equipped with a magnet for location and control. A reliable seal with the pipe wall, the action of pressure and counter pressure forms the seal to the pipe wall, compensating for minor deviations in the pipe geometry.

Features include

Sterile and closed pipe system
No dead pockets with LAUFER EHEDG certified CIP/SIP free flow shutter valves
Optimized cleaning result with dynamic DMV lip pigs
Capable of passing 90° standard bends (R= 1.5 x D)
Available with in system cleaning of the pig
Optimally suited for hygienic processes and highly viscous fast hardening media, e.g. yoghurt, dressings, softcheese, chocolate, tooth paste, etc.
Optionally 3-A 101-00 and FDA compliance

The SMV pendulum pigging systems are based on the use of static pigs which are driven by a pushing medium (product, water, air) and move back and forth between the pig launching and receiving station, thereby eliminating the remaining product from the pipe. SMV pendulum pigs are statically sealing by means of a defined oversize between the pig outside diameter and pipe inside diameter. The components used in SMV pendulum pigging systems are essential to high operating safety. The use of ball valves with minimized dead pockets is standard in view of maximum process safety. As an option, static pigs are equipped with a magnet for location and control and can be cleaned in the closed system without removing it. SMV Pigs are bi directional.
