Description
The Welch 2052B-01 Chemical Duty Diaphragm Pump is a high-performance, oil-free pump ideal for laboratory and industrial applications. Manufactured in the United States and in excellent condition, this model has seen very little use and exhibits minor to no cosmetic damage. Designed for low-maintenance operation, it features a solid PTFE head and PTFE membranes, offering exceptional chemical durability. With a free air displacement of 2.3 cfm (@60Hz) and ultimate pressure of 1.5 Torr, this pump is particularly suited for evaporating solvents like DMF and pentachloroethane in rotary evaporator volumes of up to 20L at 160°C. Its clean, maintenance-free pumping action makes it a versatile choice for a range of applications. Operating on a standard 115V power supply, the Welch 2052B-01 accommodates peak flow rates up to 65 L/min, proving itself a reliable asset for scale-up operations. While it does not come with additional software or computers, this pump includes a power cord and maintains a high standard of reliability.
