Dry Claw Pumps

Dry claw vacuum pumps are positive displacement pumps that use two claw-shaped rotors to trap and compress gas to create a vacuum. They are oil-free, low maintenance, and can operate continuously without experiencing wear and tear. They are commonly used in industrial applications that require reliable and efficient vacuum systems.

nEDC Dry Claw

Edwards range of nEDC dry claw pumps features an innovative design which creates a new benchmark in the claw pump market. The simplicity, robustness, efficiency and contaminant handling capability of these pumps make them the smart choice for your application. Built to the exacting standards and quality demanded by our customers, Edwards dry claw pump provides you with a trouble-free and cost-effective solution to meet your needs.

nEDC300

Harsh industrial applications require a pump that can withstand rough operational conditions.

Features and Benefits

  • Enhanced performance - Modular design ensures efficiency during the operational lifecycle. You are ensured of improved performance for your process due to higher pumping speeds.
  • Reliable and long-lasting - Lower internal temperatures increase lip seal life and prevents oil leaks.
  • Lower noise levels - Re-designed and in-house developed silencer significantly reduces noise levels.
  • Easy to maintain - n addition to Edwards field service, the nEDC claw pump can be easily cleaned on-site and re-started by customers without the need for specialized tools.
