Welch 1397 DuoSeal Unmounted Pump
Welch 1397 DUOSEAL Vacuum Pump – 23 CFM (Unmounted)
The Welch 1397 DUOSEAL is a high-capacity, belt-drive rotary vane vacuum pump designed for applications requiring strong pumping speed and deep vacuum. With 23 CFM (650 L/min) free air displacement, it is well-suited for large laboratory systems, industrial processes, and pilot plant operations.
Welch DuoSeal 1397 is an unmounted pump and a component to a complete belt driven vacuum pump. The Welch DuoSeal Unmounted Pump 1397 requires a base, motor and belt to generate vacuum. This product can only be used as a drop-in replacement for the pump component of a complete vacuum pump.
Key Features
- 23 CFM (650 L/min) pumping speed
- Ultimate vacuum down to 1 × 10⁻⁴ Torr
- Large oil reservoir for cooler operation and extended oil life
- Durable DUOSEAL rotary vane design
- Easy maintenance and service access
Ideal Applications
- Large vacuum ovens and drying chambers
- Pilot plant and scale-up operations
- Industrial vacuum processes
- Vacuum distillation
- Laboratory systems requiring high flow
