Variable
Speed Packaged Pumping System Closed System
The EnviroSep Model PPS-VC, Packaged Pumping System is a UL-Listed
factory assembled and tested system used for fluid handling systems
which are configured in closed circuits. The PPS-VC provides significant
power savings by automatically controlling the speed of the pump(s)
based on the actual system demand. Transmitters signal to the PPS-VC
System Controller which controls a Variable Frequency Drive for each
pump to the appropriate speed. The PPS-VC can be configured for pumping
of a variety of fluids at a controlled flow rate in any industrial
or commercial application. Process fluid enters a common system header
and by use of centrifugal pumps is pumped at a controlled flow rate
to a common discharge header. The Variable Frequency Drive may incorporate
Manual or Automatic bypasses. The PPS-VC also allows for system thermal
expansion based on the system volume. 
A UL-Listed control panel with
single-point power connection is pre-wired to all electrical sources.
Each Unit is custom engineered and designed to meet specific system
requirements. All systems are fabricated and welded per ASME Section
IX Code and Standards, and are Hydrostatically tested prior to shipment.
The Model PPS-VC speeds installation and start-up of fluid systems
which provide significant savings to contractors, engineers, and facility
owners.
