Electric barrel pump


The E-Pump is a versatile barrel pump and it is especially designed for pumping oil or grease lubricants up to NLGI grade 2 into a centralized lubrication system. 

When equipped with a change-over valve unit, as E-VALVE e.g. or a shut-off valve as E-VALVE-S e.g. it can be used either in single-line, dual-line or progressive lubrication systems. A complete pumping center consists of a pumping unit and a lid set. EPUMP-XXX-ECO coding is referring to ECO lid sets (descending pump head with follower plate), which are suitable for greases in NLGI grades 1 and 2. EPUMPXXX-STA coding is referring to STA lid sets (pump head always at barrel bottom), which are suitable for oil or greases in NLGI 0, 00 and 000 classes.

Features and benefits

  • E-Pump models reflecting typical and often used barrel sizes
  • Compact electrically operated pump for applications where no air supply is available
  • An internal pressure control and a heating element help to ensure the pump’s function under high-pressure conditions and cold climates
  • E-Pump models are recommended to replace GSE pumps
