Honda WDP30 3 inch diaphragm pump sold and serviced in Arizona by APD Power

Rock channel to help prevent damage. The connecting rod is spring preloaded. If the
diaphragm lodges against an object larger than 2.4 inches in diameter, the spring
located in the connecting rod prevents damage. Combined with the WDP30's special
rock channel, damage to the pump housing is minimized.

Since the pumping is performed by a diaphragm, the WDP30 is perfect for low volume
applications where the pump frequently runs dry.
