E-Flo 4-Ball Piston Pumps

E-Flo 4-Ball Piston Pumps 

Electric Circulating Pumps

Dual lower, 4-ball electric drive circulating pump

Get the benefits of a piston pump with the energy efficiency of an electric drive unit!

The dual lower of the E-Flo electric circulating pump minimizes pressure changes at the outlet of the pump. Online maintenance simplifies repair and reduces downtime. Accomplish remote monitoring of performance via computer or PLC for a higher degree of control.

Features :

  • Online maintenance simplifies repair and reduces downtime
  • 3 times more efficient than pneumatics
  • Process control and feedback
  • Slow smooth change overs
  • Low noise
  • Enclosed wet cup minimizes operator interaction for reduced maintenance

Sealed 4-Ball Lowers

  • No TSL required
  • Ultralife Series ceramic coating holds up to the harshest materials, including waterborne paints
  • Completely sealed fluid section can be used almost anywhere, including catalyst and moisture sensitive materials
  • Compatible with existing Bulldog, NXT, President, Viscount, E-Flo, and E-Flo DC motors
  • Open wet cup version is also available
