P212 Electric Drive Pump

For multi-line and sequential lubrication systems

This high-pressure multi-line pump can drive up to 12 pump elements. It can deliver lubricant directly to lubrication points in multi-line systems or serve as a centralized lubrication pump in large progressive systems. The eccentric shaft drive and design, highly efficient worm gear, and minimal number of parts provide this pump with several advantages. P 212 pumps are supplied with a powerful three-phase multi-range electric motor. The reservoir is suitable for both grease and oil and is available with or without level monitoring.

Technical characteristics and advantages

  • High delivery volume per pump element
  • High pressure even with problematic lubricants
  • Due to the high flow rate at the outlets of the pump elements, no connection of the outlets is required
  • A series of robust and reliable pumps operating in challenging conditions
  • Modular design
  • Easy maintenance

Application areas

  • Equipment with high lubricant consumption
  • Tunnel boring machines
  • Mining
  • Rubber mixing equipment - as a pump for liquid plasticizer
