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 Acc
u-
Flo™ descriptions are used in place of a pump model size. See
Pump Designation System chart above
.
NOTE:
Most elastomeric materials use colored dots for identification.
NOTE:
Not all models are available with all material options.
