EDC Maintenance

EDC Dry Claw Vacuum Pump Service Guide

The EDC pump is a claw, low maintenance, industrial pump that comes in sizes of 65 - 300 m³/h-1. The pump was designed for field serviceability, allowing users to perform maintenance on their own. All service activities can be done on-site, eliminating the need to send pump for repair to a service centre. Major maintenance tasks can be handled either by trained Edwards professionals or Edwards can deliver users with on-site training and tools. Another key benefit of EDC claw pump is long service intervals.  

How to make sure your EDC Edwards Dry Claw Pump runs smoothly and to lower the risk of unplanned downtime.
