Diaphragm Trash Pump
WDP30 Honda
Three inch Diaphragm Trash Pump passes rocks up to 2.4 inches.

Since these pumps don't have impellers or mechanical seals, they can pump extremely sandy gritty water and some
fairly large solids. The 3 inch Honda WDP30 can pump items as large as 2.4 inches in diameter. (slightly under 2
1/2 inches). Diaphragm pumps do not need to be "primed".

If an object larger than this pumps capacity enters the pumping chamber, the Honda WDP30 has a safety feature to
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 case is in most cases prevented.

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