THE THREE ACCU-FLO™ OPTIONS AVAILABLE:
1. AxT: This is the same Accu-Flo™ configuration that has been available from Wilden
since March 1994. An aluminum solenoid valve is attached directly to a T-series center
section and the shaft/inner piston configuration is altered.
2. AxP: This option uses a plastic (polypropylene or acetal) spacer that is assembled
between the Pro-Flo
®
air valve and the Pro-Flo
®
center section. The same solenoid
operator – coil assembly that is found on AxT pumps is assembled on the plastic spacer
discussed above for electronic interface. This spacer together with the Pro-Flo
®
air valve
replaces the aluminum air valve used in the AxT with a more chemically resistant option.
Spacers will be available in the 1/4”, 1/2”, and 1” sizes. The use of the Pro-Flo
®
ADS
provides additional flow in most applications (refer to EOM for details). The AxP provides
the Pro-Flo
®
benefits of lower start-up pressure, reduced blow-by, and increased life.
3. AxB: This option uses an Adapter Block in place of an air valve. A user supplied, 4-way
pneumatic valve must be used in conjunction with this technology. This configuration
enables the solenoid valve to be remotely installed, preventing chemical attack in very
aggressive environments. Adapter Blocks are available for both the T and P-series center
sections in all pump sizes. (See EOM AxB for details.)
Note: The “x” in the above Accu-Flo™ descriptions are used in place of a pump model
size. See Pump Designation System chart above.
