Designed to integrate transfer lines perfectly, FlowTherm brings you the Servinox pigging system, intended to recover the residual mass in the piping using a pig. The pig is positioned upstream of the zone to be evacuated, then sent in the piping by a thrusting fluid (gas or liquid).

The standard equipment comprises a launching station, a receiving station and a pig. It can be completed by full flow multi-way valves (MV), which can be used to adapt the lines in order to optimise the pigging phases. Pigging control can be manual or automatic with a pig speed control unit (RVO).


  • Reduction in product losses (recovery above 99.5%)
  • Pigging of all products transported in piping (viscous, solid bearing, solidifying, etc.)
  • Enhanced line use flexibility by limiting the risks of cross-contamination
  • Elimination of the dilution phenomenon induced by water thrust without a pig
  • Reduction in the volumes of effluent to be treated
  • Reduction in the consumption of cleaning agents and washing cycles
  • Reduction in the operating costs and return on investment as of the first year of use
  • Customised system that adapts to all types of requirements and constraints


  • Transfer line pigging for all types of liquids
  • Equipment especially adapted to the lines distributing viscous, solid bearing and/or solidifying liquids (creams, chocolate, caramel, etc.)

Servinox RVO

Pig control panel for process or transfer lines and all types of fluids

The RVO Pig Speed Control Panel continuously and autonomously adjusts the pig’s push pressure to the most appropriate pressure. It is used to instantly control the pig’s travel speed during the pigging.
This system can be used irrespective of the particularities of the line to pig or the product to recover.

“Know how to anticipate the essential flows and pressures to control the pigging”


  • Reduction in product losses (recovery above 99.5%)
  • Protects the lines from pressure surges
  • Prevents the pig from blocking
  • Eliminates the product’s “Karcher” effect on arrival
  • Ensures user safety and the security of the installations
  • Adapts to different kinds of products that can be transferred on the same line
  • Increases the pig’s life
