Welch 2522 Dry Vacuum Pump — Request a Quote

mLab Supply helps laboratories source the Welch 2522 Dry Vacuum Pump, along with comparable new, used, and refurbished options when available.

The Welch 2522 is an oil-free diaphragm vacuum pump designed for general laboratory vacuum applications. Dry diaphragm pumps are widely used where oil contamination of the vacuum line or sample is unacceptable, and are commonly found in filtration, evaporation, and aspiration workflows in pharmaceutical, academic, and research laboratory environments.

Common Applications

• Vacuum filtration (membrane filtration, Buchner funnel)
• Rotary evaporator vacuum source
• Gel drying and vacuum manifold applications
• Aspiration and liquid waste removal
• General laboratory vacuum workflows requiring an oil-free source

Configuration Considerations

• Confirm ultimate vacuum and pumping speed for your application
• Verify inlet and exhaust port configuration and fitting compatibility
• Confirm chemical compatibility of pump materials with your solvents or vapors
• Verify power requirements for your facility
• For regulated applications, confirm available calibration and service documentation

What to Verify When Sourcing a Used Unit

• Diaphragm and valve condition — these are wear items and may need replacement
• Vacuum performance and ultimate vacuum achievable
• Inlet and exhaust fitting condition
• Included accessories (tubing, fittings, traps)
• Preventive maintenance and service records

Pump configuration, vacuum performance, included accessories, condition, service history, and availability may vary by sourced unit. mLab Supply is not an authorized Welch dealer.
