The actual speed of filtering is driven by how deep a vacuum the pump can pull the flasks to.
The Welch 2546B-01 winterization / filtration vacuum pump not only quickly evacuates, but it also pulls to 92% vacuum. That means even a bigger pump with 99.99% vacuum would deliver only 8% faster filtering speed.
The Welch 2546B-01 winterization / filtration vacuum pump has a built-in liquid ingestion prevention system; the ball in the cup floats up if any liquid overflow streams in, blocking the inlet.
It also has vacuum gauges and even vacuum control.
