Benefits to retrofitting your existing T-Station with the Edwards mXDS3 Dry Scroll

By retrofitting your T-Station 85 or 300 with an mXDS3 Dry Scroll Pump, customers can enjoy a more efficient, reliable, and user-friendly vacuum system that not only meets but exceeds the performance of conventional vacuum pumps, making it a wise investment for anyone prioritizing operational efficiency and cost-effectiveness.

Key Benefits To Retrofitting Your T-Station With An mXDS3 Scroll Pump

  • Enhanced Efficiency: The mXDS3 pumps improve overall system efficiency, crucial for both energy savings and performance enhancement.
  • Greater Pumping Speeds: With pumping speeds of 3 m³/h, the mXDS3 offers a significant upgrade over diaphragm and small rotary vane pumps, ensuring faster pump-down times and improved productivity.
  • Compact and Lightweight Design: The new pumps have a smaller footprint and are lighter, making them easy to integrate into existing systems without the need forextensive modifications.
  • Superior Ultimate Pressure: Achieving a better ultimate pressure of 0.1 mbar, the mXDS3 scroll pumps ensure a higher vacuum level, which is critical for many research and development applications.
  • Reduction in Pump-Down Time: With the mXDS3, the pump-down time is significantly reduced, which means quicker transitions to operational readiness.
  • Power Failure Protection: The fully configured mXDS3s variant supplied with factory fitted delay opening inlet valve provides added security against power failures, preserving system integrity and vacuum conditions.
  • More Compact with Exhaust Filter: Its integrated exhaust filter design adds to the compactness of the pump, making it a space-saving solution.
  • Lower Maintenance Costs: With less frequent maintenance required and reduced operational costs, the mXDS3 is a cost-effective option over the long term.
  • User-Friendly Maintenance: The easy-to-replace tip seals only need servicing every two years, and the pump is designed for end-user serviceability, which minimizes downtime and technical support dependence.

Retrofit Step-By-Step Guide

EDW_Retrofit Guide Steps 1 and 2


Step 1: Disconnect old roughing pump from system by releasing clamps on flex hose and turbopump elbow. Discard old hose and O-rings, but keep existing elbow and clamps.

Step 2: Next, unfasten bolts from baseplate connecting old pump and replace with new mXDS3. Bolt holes will line up allowing for easy fastening of new pump to baseplate.

Step 3: Use two new O-rings for clamps that were connected to both ends of existing turbopump elbow on your system using P/N B27158427 and reuse old clamps.

Step 4: Replace old flex hose with new longer hose, P/N C10512286, and fasten to old elbow on turbopump using old clamps and new O-rings.
