Frequent colour changes or small
batch sizes?

... then this gear pump is the ideal solution. The extrex RQ series features first-class manual cleaning compatibility even while installed. The entire pump can be dismantled without restriction. This means that the systems operator has to spend only a short time on cleaning and benefits from improved access for inspections.

Shafts / bearing packages prepared especially for this are replaced in seconds once the pump has been mechanically dismantled. The interior of the pump is freely accessible once the housing halves have been separated and the rotor package has been removed. There is also no need to open and close adapter flange screws above and below the pump, since the product channel to both the extruder tip and the extruder head is freely accessible.

There are two types available:

  • extex RV-Q for 40% more throughput with retention of the basic dimensions per size
  • extrex RB-Q for high-pressure applications involving up to 500 bar counterpressure

Benefits

  • Reduces time and effort spent on cleaning
  • Minimises handling costs
  • Shaft / bearing package rapidly exchangeable
  • Various tooth geometries are available and can be exchanged at any time
