Return pumping station RRH


Integrated pump-back stations are compact conveyor systems for integration into a machine bed. The main purpose of the unit is to automatically transport small to medium quantities of chips and cooling lubricant from the machine tool to a separator/filter. This construction unites the characteristics of conventional solutions from chip conveyors and separate pumping stations into a combined unit. Cooling lubricants and chips that result during the cutting of materials such as steel, cast iron or aluminium are particularly suitable. 



Fully automatic cooling lubricant and chip transport

No manual intervention required

Compact design due to machine integration

Occupies little space outside the machine

Low overall height

Ideal for automation systems

Chip reducer can be retrofitted

Adaptation to expanded requirements

Customised conveyor trough

Chip holder can be adapted to machine

Maintenance areas outside the machine Easy accessibility

Combination options

For further requirements, we can combine integrated pump-back stations on request with 

  • Chip reducers to achieve pumpable chips 
  • Centralised separator/filter systems for cleaning the cooling lubricant and supplying the machines 
  • Suction stations for further transport of the chips to the central system and the container station 
  • Centrifuges and briquetting systems for further treatment of the chips

Main Functions

  1. Collection of small quantities of short chips together with cooling lubricant in the trough
  2. Transporting the chips with the aid of a gradient and flushing into the pump-back tank to the return flow pump
  3. Transporting the chip/cooling lubricant mixture through the return flow pump to the separator/filter system
