Pulsatron LE14 Pulsafeeder

Pulsatron LE14 Pulsafeeder electronic metering pump are solenoid powered diaphragm metering pumps. The key element which differentiates these pumps from other types is the TFE lined elastomer diaphragm. This diaphragm is sealed against the reagent head forming a seals – less, leak free pumping chamber. The solenoid driver is connected to the diaphragm to create the pumping motion. As the diaphragm moves away from the face of the reagent head, it creates a vacuum which closes the discharge check valve and opens the suction check valve, drawing the pumped fluid into the pumping chamber. As the solenoid forces the diaphragm towards the face of the reagent head, the suction check valve closes and the discharge check valve opens allowing the liquid to flow out the discharge valve.

Key Features :

  • Manual control
    By on – line adjustable stroke rate and stroke length
  • Agency approved for demanding outdoor and indoor applications
  • Highly reliable timing circuit
  • Water resistant excellent for outdoor and indoor applications
  • Internally dampened to reduce noise, very acceptable for household installations
  • Guided ball check valve system, to reduce back flow and enhance outstanding priming characteristics
  • Premium standard wetted component materials
  • Few moving parts and wall mountable
  • Safe and easy priming with durable leak-free bleed valve assembly (standard)
