Sampi rotary vane positive displacement motor pump units for fuel and
chemical applications 


Sampi fuel & oil motor pumping sets are designed to handle non-aggressive chemical and petrochemical fluids and can be installed in classified areas (with explosion or fire hazard), unless the customer requests special constructions for specific uses.

Common applications for a motor pump set include:

  • Liquid transfer in terminal and bulk plants
  • High flow dispensers
  • Combined pumping and metering systems
  • Mobile pumping units
