E-Flo 4-Ball Piston Pumps

E-Flo 4-Ball Piston Pumps

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

E-Flo DC 4-Ball Piston Pump

E-Flo DC 4-Ball Piston Pump

Our E-Flo DC (Dual Control) electric circulating pump has been found to be up to five times more efficient than similar
sized pneumatic pumps. Watch the video below to hear how our pump can reduce noise levels, plus it will help to lower
your energy bill and save you money.

Features

  • Five times more efficient compared to similar sized pneumatic pumps
  • Minimal pulsation at changeover provides a more consistent finish
  • Integrated runaway protection protects your pump from premature wear and prevents costly material loss
  • Basic model has two simple control knobs to easily adjust pump settings
  • Advanced model lets you easily connect and manage multiple pumps with a single control module
  • Quiet electric motor improves your work environment allowing you to remain near the pump for longer periods of time

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
