EVC-0405

The EVC-0405 Dry Running Claw pump

The EVC-Series pumps are dry contact-less vacuum pumps with modular constructions consisting of compartments: pumping and gear chambers are separated by using labyrinth seals. As two claws rotate in opposite direction, the air will be sucked in the pumping chamber, compressed and discharged under pressure. Two gears for synchronizing of claws rotation are placed inside the gear chamber and lubricated with appropriate gear oil. A built in anti-suck back valve installed in inlet flange will prevent the air from flowing back into the vacuum chamber when the pump is shutdown. The pumps are directly driven by a flanged motor via a coupling. The claws and compression chamber have a TFE (Teflon) coating to protect the pump against corrosion from water in the pumped gasses.

Advantages to the user:

  • High pumping speed
  • Oil free pumping chamber
  • Corrosion protection by teflon coating
  • Air cooling, no cooling water needed
  • Very little maintenance needed
  • Non contact claw rotation
  • Direct drive
  • Anti-suck back valve to secure vacuum
