Annovi Reverberi AR403 / AR303 Diaphragm Pump Repair Kits

Keep your Annovi Reverberi AR403 or AR303 Diaphragm Pump in excellent working condition for the remainder of the spraying season by replacing any wearing parts with the replacements included in these Annovi Reverberi AR403 / AR303 Diaphragm Pump Repair Kits. These kits also can be used on the discontinued Hypro 9910-D403 and 9910-D303 Diaphragm Pumps.

If your diaphragm pump is being run constantly, you should be replacing the diaphragms every 3 months or after 500 hours of use, and replacing the valves and o-rings every 6 months or after 1000 hours of use to avoid a decline in performance. If there is a milky grey color in the oil sight glass, stop running the pump immediately and replace the diaphragms because this is an indication the diaphragms have been damaged. Using your diaphragm pump with ruined diaphragms can cause serious damage.

BlueFlex diaphragms are manufactured with some of the best performing diaphragm material available, establishing a new benchmark for diaphragm durability under the toughest working conditions, whether you are handling weed killers, fungicides, pesticides, liquid fertilizers or hard-to-handle liquids and aggressive chemicals. The unique shape and thickness of the BlueFlex diaphragms have been carefully optimized to reduce mechanical stresses during the pump's working cycle, even under the toughest working conditions.
