Car Wash Pumps Nozzles and Spray Arms
PRODUCT PARAMETERS
Weile car wash pumps, spray nozzles and spray arms must match the installed circuit. Select replacements using the part code, working pressure, flow and interfaces. Evaluate wetted materials and chemical compatibility for the actual wash duty.
