Description

What is the Non-Reversing Bulk Pump 
Assembly?

The Conair Non-reversing Bulk Pump system comes complete with a pump assembly, 
4-way valve, and a non-reversing bulk control capible of handling up to four silos or bins. 
Through the use of the 4-way valve, a reverse air flow is created for filter cleaning without 
the complexity of motor and pump reversal. The control enclosure has complete hook-up 
and control facilities for the loading of four different bins and care should be taken during 
installation to assure that all connections are in complete accordance with the accompany-
ing wiring diagram.
