2-2 General Description
Our material conveying systems create vacuum for the automatic conveying of most free- flowing, dry, pelletized, or granular materials. Material characteristics determine the type of equipment needed to convey the material.
A typical use for our equipment is an
Our central vacuum systems are as varied as the applications they service. The tubing and equipment furnished in our system is designed to convey the material(s) specified at the time of purchase at specific rates and distances.
We can advise you on your system capabilities based on system makeup, distance, material, and conveying rates you want.
System capacity is directly affected by the pressure drop in the overall system, such as number of material line bends, pipe length,
Use the minimum effective amount of vinyl flex hose to maximize material line efficiency. Keep material lines as straight as possible. Refer to the Mechanical Components Product manual (Part No. A0536580) for installation recommendations.
Note: Vacuum leaks occurring anywhere in your system reduce capacity.
2-3 Standard Features
Mechanical Features
Vent Valve. The vent valve unloads the vacuum pump motor and allows it to keep running during short periods when material conveying is not required. Constantly starting and stopping the vacuum pump will damage it over time. The vent valve also protects the conveying system from damage during high vacuum conditions. The valve plunger will unseat itself and allow ambient air to leak into the vacuum lines when the vacuum climbs too high.
Central Purging. This feature allows any remaining material to be cleaned out of the material line after every convey.
Local Blowback Filter Cleaning. When this feature is enabled, the controller periodically sends compressed air backward through the pump’s air filter to dislodge accumulated dust and debris.
