Welch Vacuum Application I Vaccum/Pressure Control with Welch Single-Head Wob-L Pumps
How Welch’s WOB-L technology simplifies lab vacuum and pressure workflows
Labs running filtration, aspiration, or degassing processes often face inconsistent vacuum levels, noisy operation, and frequent maintenance. Welch’s single-head WOB-L pumps address these issues with oil-free performance, stable control, and compact design—ideal for benchtop setups where reliability and footprint matter.
This video walks through how the WOB-L pump works, what makes it different, and where it fits best. It’s designed for lab managers, technicians, and procurement teams evaluating vacuum solutions for routine tasks.
Why WOB-L Pumps Matter
Welch’s WOB-L pumps use a piston-driven mechanism to deliver consistent vacuum and pressure without oil contamination. That means fewer service interruptions and cleaner results. The single-head configuration is optimized for moderate-duty applications like:
- Vacuum filtration
- Solid-phase extraction
- Degassing liquids
- Aspiration of biological samples
Compared to diaphragm pumps, WOB-L units offer higher flow rates and better pressure stability. They’re also quieter than rotary vane systems and require less maintenance.
