Diaphragm Pumps, Self Priming

Accu-Flo™ Series Electronic Control Pumps

How It Works
The Accu-Flo Air Distribution System (ADS) employs a two-position, four-way solenoid valve that has a single operator and spring return. The valve is internally air-piloted for longer coil and operator life.

• Air pressure is utilized to fill air chambers and displace the diaphragms, but electrical impulses dictate the stroke rate.
• When the solenoid is unpowered, the air valve piston is held by a spring to the top of the air valve body.
• In this position, the air supply is directed to the right side of the pump while the left air chamber is exhausted.
• When the solenoid is powered by electricity, air pressure is routed to the top of the air valve piston, which overcomes the tension of the spring and forces the piston down.
• In this position, the air valve piston directs the air supply to the left side of the pump and exhausts the right side.
• By alternately applying and removing electrical power, the Accu-Flo Series pump reciprocates back and forth in a fashion similar to standard air-operated pumps.

ACCU-FLO AIR DISTRIBUTION SYSTEM
Uses a two-position, four-way solenoid valve that allows the pump to alternate between air and electricity.

ACCU-FLO™
Precisely controls the stroke rate of the pump and more accurately controls the fl ow rate for dosing applications.

BORE SEAL
The bore-seal design relies on a fastener force that is perpendicular to the seal to optimize the sealing capabilities which eliminates leaks that result from torque decay.

DETACHABLE MOUNTING FOOT
Featuring the industry’s fi rst detachable mounting foot, the Velocity Series offers adaptable mounting capabilities. Additionally, the Velocity footprint is interchangeable with previous Wilden designs (P.025, P25 and P1, P100).

ADAPTABLE MOUNTING CAPABILITIES
The Velocity Series can easily be reorientated into avertical or horizontal position with multiple inlet and discharge port options. With this feature, it has been designed with skids and systems in mind to fi t perfectly into restricted spaces.
