Gast DOA-P707

This is a used Gast DOA-P707 diaphragm vacuum pump, a compact oil-less unit widely trusted in laboratory and light industrial settings for clean, dependable vacuum and pressure generation. The pump has been tested and remains in good working order, showing typical cosmetic wear from prior service but with no compromise to its mechanical performance. Its diaphragm design means no lubrication is required, which keeps the air stream free of oil contamination and simplifies ongoing maintenance for the next owner. The DOA-P707 is prized for its quiet, continuous duty operation and small footprint, making it a favorite for benchtop applications such as filtration, aspiration, gas sampling, and vacuum-assisted instrumentation. Its dual-purpose capability to run as either a vacuum or a compressor gives users flexibility across a range of laboratory workflows, from sample degassing to fluid transfer support. The unit is well suited for OEM integration into analytical devices as well as standalone bench use. This pump is being sold as a used, functional unit with normal wear expected of previously installed equipment. It is a great fit for labs, service technicians, or OEM manufacturers looking for an economical replacement or spare that delivers the same reliable Gast performance associated with new units, without the new-unit price tag.
