Desmopan vs. BlueFlex Diaphragms

The AR 43283 Desmopan Kit is a suitable option for compatible pumps used in pest control applications. For landscape spraying applications, consider the AR 43285 BlueFlex Diaphragm Kit, which uses a different diaphragm material.

Always confirm diaphragm material compatibility with the chemicals being sprayed and the pump manufacturer's recommendations.

Diaphragm Maintenance & Replacement

Diaphragms are wear components that flex continuously during pump operation. Over time, they may crack, deteriorate, or rupture, reducing pump performance and potentially allowing spray liquid to enter the crankcase.

Common signs that diaphragm replacement may be needed include:

• Milky or Cloudy Pump Oil: May indicate spray liquid has entered the crankcase through a damaged diaphragm.
• Reduced Pump Performance: Lower-than-normal flow or difficulty maintaining operating pressure.
• Visible Diaphragm Damage: Cracks, tears, or deterioration discovered during inspection.
• Oil Contamination: Evidence that spray liquid and pump oil have mixed.

Maintenance Recommendations:

• Replace both main pump diaphragms together during diaphragm service.
• Inspect and replace the accumulator diaphragm as needed.
• Inspect O-rings, valves, and sealing surfaces for damage or wear.
• Check pump oil for contamination and replace it according to the manufacturer's service instructions.
• Follow the pump manufacturer's assembly procedures and torque specifications.

Important: If pump oil appears milky or contaminated, stop operating the pump and inspect the diaphragms promptly. Before servicing, shut off the equipment, disconnect the power source, and relieve all system pressure.
