Accu-Flo Solenoid Pump Technology
Enjoy the benefits of wilden air operated, double diaphragm pumps while achieving greater control in batching, metering, and other electrically controlled dispensing applications. Accu-Flo pumps interface directly with a wide variety of electronic devices enabling you to fully automate your process. Utilizing compressed air as a driving force to displace process fluid, Accu-Flo pumps have many of the same features as standard Wilden air-operated pumps.
The Wilden Accu-Flo air valve uses electrical impulses to stroke the pump, instead of pressure differential as does the standard Wilden air valve. This valve is a two-position, four-way solenoid valve that has a single operator and spring return. The valve is internally air piloted for long coil and operator life.
When the solenoid is unpowered, one air chamber withing the pump is pressurized with air, while the opposite chamber is exhausted. When electric power is applied, the solenoid shifts, and the pressurized air chamber is exhausted while the opposite chamber is pressurized. By alternately applying and removing power, the Accu-Flo pump runs like a standard Wilden pump.
Wilden Accu-Flo pumps have the following inherent features:
- Interface directly with electronic devices
- On/Off reliability
- No lubrication needed
