Welch Vacuum is a long-established provider of laboratory vacuum pumps, recognized for application-driven designs that balance durability, chemical compatibility, and vacuum performance. Welch Vacuum Pumps support a wide range of laboratory processes where controlled vacuum level, operational stability, and material resistance are critical.
The product range spans Direct Drive Rotary Vane Vacuum Pumps, Belt Drive Pumps, and Explosion Proof Rotary Vane Vacuum Pumps, offering options for standard duty and high-vacuum manufacturing environments. Rotary vane systems with gas ballast valves are commonly selected for organic solvents, wiped film, short path distillation, and refrigeration rotary vane vacuum pump applications. For chemically aggressive workflows, Welch diaphragm pumps incorporate PTFE diaphragms, PTFE heads, fluorinated plastics, and chemical resistant coatings to support filtration pump duties, vacuum impregnation, solid phase extraction, and Buchner funnel filtration systems.
Welch oil-free diaphragm vacuum pumps—including ChemStar Dry Vacuum Pump, Gemini Dry Vacuum Pump, DryFast Chemical Duty PTFE Diaphragm Vacuum Pump, and other chem duty diaphragm pump configurations—are engineered for clean operation, advanced vapor management, and reduced maintenance. The CRVpro family and Welch CRVpro series address higher pumping capacity needs, while WOB-L Pressure Dry Vacuum Pumps such as the 2522 WOB-L Standard Duty Piston Pump and Welch 2585 WOB-L Standard Duty Piston Pump support preparative procedures, gas sampling, and field or lab filtration.
MSE Supplies LLC provides access to Welch Vacuum Pumps and compatible vacuum components, supporting laboratories with reliable sourcing for rotary vane, diaphragm, and chemical duty vacuum solutions used in analytical, preparative, and process-driven applications.
