By industry definition, a wet-end kit is a pump end, unassembled, and without engine. Some technical competence is required for correct assembly; servicing personnel who can rebuild a pump will typically have no problem assembling a wet-end kit. For mounting flange and engine shaft requirements, please contact us for more information. Please note that Wet End Kits do not include roll cages, except for the DP2X. Order Roll Cage Kits seperately, if required. Pumps are shown assembled but are shipped unassembled except as noted.
