During the discharge stroke, the suction balls seats, preventing solution from going back to the solution tank. The solution is forced through the discharge valve.

Coil is de- energizedCoil is de- energized Springs return the armature and shaftSprings return the armature and shaft Liquifram™ is pulled back, creating vacuumLiquifram™ is pulled back, creating vacuum Suction Stroke Basic Pump Operation

During the suction stroke, a vacuum is created. The head cavity fills as the Liquifram returns. The suction ball rises while the discharge ball seats.
