High-vacuum pumps increase conveying efficiency, decrease energy consu

Plugged conveying lines, starved machines, and insufficient throughput capacity are some of the problems designed to be solved by two new pumps for use in high-vacuum polymer conveying applications. The MVP (MaxFlo Vacuum Pump) series and UVP (UltraVac Vacuum Pump) series are said to generate higher vacuum levels at a modest price premium versus traditional positive displacement pumps.

Shown is the UVP-9 from Novatec.

Higher vacuum is an alternative to increasing line size, which reduces pressure drop but increases energy usage. The MVP and UVP convey more material over longer distances, up to 1000 equivalent feet or more as compared to conventional pumps, without increasing line size, explains the manufacturer of both, auxiliary machinery supplier Novatec (Baltimore, MD).

Use of the MVP and UVP pumps allows system expansion, increased throughput and conveying distance, conveying to multiple destinations with one pump, and decreased energy consumption. The MVP series is rated for operation up to 16 inches of mercury (Hg). The manufacturer's spiral flow pump technology keeps the noise down so that noise reduction blankets are not needed.

The UVP series, in 6- and 9-hp models, is rated for operation up to 22-26 inches (Hg). Oil changes on the direct drive motor are necessary only every 12 months.
