By the nature of the liquid ring pump the air being discharged is at 100% humidity but also carrying a lot of entrained liquid. The liquid and gas being discharged from the vacuum pump are usually separated in a device called a discharge separator. This discussion is about the discharge separator for applications where water […]

The Living Dead Vacuum Pump

With Halloween approaching, I thought it appropriate to discuss the living dead pump. It really isn’t quite dead as it continues to use horsepower and saps the strength of your vacuum system.   It is possible that in your mill somewhere in the past an engineer noticed that the vacuum at the couch was 14 […]

The Condensation Effect on Liquid Ring Vacuum Pumps

July 23rd, 2015 Posted by Andy Smiltneek

There are two major designs in liquid ring vacuum pumps. They are cone ported and flat sided. The smallest pumps are usually flat sided, as they are easier to manufacture. The largest vacuum pump commercially produced is cone ported, as it is most efficient and handles excess water better than a flat sided pump. The […]

Sizing a Liquid Ring Vacuum Pump Drive

This article addresses the sizing of a custom drive for a larger vacuum pump, in the range of 20 to 3000 HP. The small pumps with integral drives have already been sized by the manufacturer, so you need not worry about those. The principles are the same, but the capital cost and power used are […]

Power Consumption of a Liquid Ring Vacuum Pump

June 18th, 2015 Posted by Andy Smiltneek

This article describes how to predict the power consumption of the liquid ring vacuum pump. This is the first step in sizing a vacuum pump drive.  The vacuum pump can also be the largest consumer of energy in your process and a significant number in your cost analysis. Approximately two-thirds of the energy that goes […]

How Large Of A Vacuum Pump Do I Need?

Vacuum refers to a space where the density of the gas is less than the density of the air in the environment around it. This density is expressed as gas pressure. At sea level the air pressure is defined as 14.7 psia. If you have a container that is at a lower pressure, it is […]
