Vacuum Pump Modulation

Modulation is a patent pending program logic that improves the manner in which your vacuum system functions. Previous designs required vacuum pumps to turn on at 16”Hg and off at 20” Hg regardless of the situation within the vacuum system. The modulation sequence controls the speed of the vacuum pumps to maintain a tighter vacuum range and speeds up and slows down depending on the demand of the vacuum system.

Unique Selling Point

Decrease power cost up to 25-35%
As the vacuum pump speed fluctuates depending on the demand, it is unusual for the pumps to ever operate at full speed. Furthermore, the pumps are not turning on and off as frequently, which reduces the power requirements to start the pumps. Therefore, running at lower speeds and reducing pumps starts decreases the power consumption.

Less heat and noise
As the pumps are normally operating at 30% of full speed, the pump does not create the maximum heat and noise.

Improved vacuum system efficiency
Even though the vacuum pumps are operating at lower speeds, the pumps are constantly pulling liquid from the pipe. Therefore, there is less water in the pipe and more vacuum. As a result, the end of line vacuum levels drastically improve. From our experiences, with modulation there is normally 2-3” Hg loss between the station and end of the line. With these high vacuum levels throughout the entire system, it will help overcome system imbalances related to waterlogging, excessive demand, etc.

Note: With the traditional 16-20” Hg logic, there could be a 10” Hg
vacuum loss between the station and end of line.

Insights

The Busch Mink pump has replaced the R5 series pump as the Airvac standard. Furthermore, Busch has modified certain models of the Mink pumps specifically for Airvac for use in a vacuum system. The result is leading edge vacuum pump technology available for use in existing and new vacuum systems.


Mink Pumps

Compared to the R5 pump, the Mink pump offers these advantages:

• They are more efficient than the R5 pumps

• They can operate at variable speeds (modulated) w/out affecting system performance

• They do not use oil which eliminates oil changes

• They save space in a stackable configuration


Modulation

By adding VFD’s and modulating the Mink pump, these additional benefits result:

• Significant savings in power costs

• Much quieter when operated at partial speed

• Pumps react to system demands without an operator responding

• Peaks and valleys of vacuum levels are evened out

• Overall reduction in maintenance costs
