The Welch 2546B-01 Dry Pressure/Vacuum Pump is a versatile, oil-free solution designed for laboratories and industrial settings requiring both vacuum and pressure modes. This compact, low-maintenance diaphragm pump operates on 115V/60Hz, single phase power and is ideal for applications such as vacuum filtration, aspiration, pressure transfer, degassing, and pressurization of lab systems.
With a chemically-resistant diaphragm design, the pump handles air and mild vapors with ease. Its oil-free nature eliminates contamination risks and significantly reduces maintenance, making it ideal for clean environments like research labs, biotech, and pharmaceuticals.
The dual-mode functionality—switching between pressure and vacuum—makes the 2546B-01 uniquely flexible for multi-step protocols and equipment setups requiring alternating functions.
