This chart is meant to be (atmospheric pressure) and pipe friction loss all affect the a guide only.
SECTION 7A INSTALLATION – T4 METAL AIR-OPERATED PUMPS The Model T4 Metal pump has a 38 mm (1-1/2") inlet and 5. PIPING: Final determination of the pump site should not 32 mm (1-1/4") outlet and is designed for flows to 307 lpm be made until the piping problems of each possible location (81 gpm).
SUGGESTED INSTALLATION ® Accu-Flo™ pumps: Accu-Flo™ pumps function with solenoid valves and require an electrical control circuit to supply pulses. Under normal operating conditions, the control circuit is sufficient for starting and stopping the pump. However, the shut off valve (user supplied) installed in the air supply line can be used to stop the pump if necessary.
SECTION 7C OPERATING PRINCIPLES BEHIND ACCU-FLO™ PUMPS In Accu-Flo™ pump models, the standard air valve is replaced Although the speed of the pump is controlled electrically, with a two position, four-way solenoid valve that has a single the air pressure is important. Air pressure displaces the fluid, operator and spring return.

SECTION 8A T4 METAL DIRECTIONS FOR DISASSEMBLY/REASSEMBLY CAUTION: Before any maintenance or repair is attempted, the compressed air line to the pump should be disconnected and all air pressure allowed to bleed from the pump. Discon- nect all intake, discharge, and air lines. Drain the pump by turning it upside down and allowing any fluid to flow into a suitable container.

SECTION 8B TURBO-FLO™ AIR VALVE/ CENTER BLOCK DIRECTIONS FOR DISASSEMBLY/REASSEMBLY The air valve assembly consists of both the air valve body and CENTER BLOCK AIR VALVE BODY piston and the center block. The unique design of the air valve relies only on differential pressure to effect the diaphragm shift. It is reliable and simple to maintain.

Small nicks can usually be dressed out and the piston returned to service. Inspect the cylinder end caps (P/N 04- 2300-23 has the piston guide pin and P/N 04-2330-23 does not.) Make sure that the guide pin is straight and smooth or the piston will not move freely in the cylinder.
SECTION 8C REASSEMBLY HINTS & TIPS ASSEMBLY: Upon performing applicable maintenance to the air distribu- tion system, the pump can now be reassembled. Please refer to the disassembly instructions for photos and parts placement. To reassemble the pump, follow the disassem- bly instructions in reverse order.
SECTION 8D GASKET KIT INSTALLATION The Wilden T4 cast iron pumps require PTFE gasket tape on the liquid chambers (P/N 04-9502-99). Other pump types may use PTFE gasket kits for additional sealing character- istics. During reassembly follow the procedures listed in your pump’s Engineering, Operation and Maintenance manual.
