Page 12: Section 6: Suggested Installation, Operation
Section 6 Suggested Installation, Operation, Maintenance and Troubleshooting All Wilden pumps are manufactured with a variety of materials for the air Piping: Final determination of the pump site should not be distribution system, liquid path and elastomers. This variety is offered to made until the piping problems of each possible location have satisfy the temperature, chemical compatibility, abrasion and flex life been evaluated. - Page 13 Suggested Installation, Operation, Maintenance and Troubleshooting Operating Principles Behind Accu-Flo™ Pumps When the solenoid is unpowered, one air chamber is pressurized There are three coil voltage options available. One coil allows for 24V with air, while the opposite chamber is exhausted. When electric DC operation.
