Summary
What are ultra high efficiency vacuum pumps used for in conveying?
Ultra high efficiency vacuum pumps are used for large resin throughputs over long conveying distances. They provide very high vacuum capacity with a steady performance curve across the operating range, reduce energy costs, and can lower installation costs by moving more material through smaller lines. They come in sizes up to 15 Hp, work with 1.5 to 3 inch lines, and provide 16 in. Hg operating vacuum.
These ultra high efficiency vacuum pumps reduce energy costs while providing very high vacuum capacities for large throughputs of resin over long conveying distances. They have a steady performance curve over the entire operating range. These are superior pumps that not only save in energy costs but also can reduce system installation costs by moving more material through smaller line sizes. Sizes range up to 15 Hp but with much higher performance ratings than pumps of comparable sizes.
Ultra High Efficiency Pumps can be used with 1.5 – 3” diameter lines and provide 16” Hg of operating vacuum.

Frequently Asked Questions
What line sizes work with ultra high efficiency vacuum pumps?
Ultra high efficiency pumps can be used with conveying lines from 1.5 to 3 inches in diameter and provide 16 in. Hg of operating vacuum. Because they move more material through smaller line sizes, they can reduce system installation costs.
How do ultra high efficiency pumps compare to other pumps of the same size?
Ultra high efficiency pumps are offered in sizes up to 15 Hp, but they carry much higher performance ratings than pumps of comparable size. They hold a steady performance curve over the entire operating range and reduce energy costs while delivering very high vacuum capacity.
