MAINTENANCE BEST PRACTICES AND SAFETY CHECKLIST FOR DUAL DIAPHRAGM PNEUMATIC PUMPS.

As pneumatic double diaphragm pumps are responsible for maintaining the flow of fluid safely and efficiently through the plant's branches. When a pump fails, it can cause accidents and also financial losses for the company.

To help keep your AODD pumps in operation much longer. Here are some tips:

> Air Filter Regulator: A low cost, safety option for your pump, filter regulators provide protection for diaphragm pumps powered by compressed air, controlling the inlet volume and pressure. Filter regulators are also essential to ensure that clean, dry air is feeding the pump, it is very important to keep compressed air dry and free of debris.

> Valves: lost products can be expensive, some potentially dangerous. When a diaphragm pump needs maintenance, it is important that you isolate the pump from the system before disassembly. The closer the valves are installed to the pump manifolds, the better. After the valves are closed, you can safely disconnect the suction and discharge manifolds.

Gauges: When problems arise, it's good to have as much system information as possible. With the right gauges, it can help you troubleshoot the pump for pressure spikes, worn air side components, thermal expansion, or check valve failure.

PRE-INSTALLATION CHECKS

Upon receiving your pump, please check the box for damage. After checking the contents (ie pump, manuals and accessories), refer to the service and operation manual. Inside the manual you will find everything you need to know about your pump, including safety information.

PREVENTIVE MAINTENANCE CHECKS

Do not wait for the failure to occur. Develop a preventive maintenance plan that includes verification of:

> Airline filters

> Leakage in suction or discharge connections

> Rhythmic Cycling

> Pressure gauges

Once you are able to track down one or two failures, this will allow you to understand the mean time between failures of your pumps. Assuming the failures were not by chance but due to wear and tear, then you should be able to put together a preventive maintenance plan for component inspection and replacement. Remember, there are an infinite number of chemicals, working temperatures and pressure points, each application can be a little different.

For quick and easy pump maintenance, check with your pump manufacturer or local distributor for complete air side and wet side repair kits.

WHAT TO CHECK IN OLDEST PUMPS

Generally, if the pump is running and an excessive amount of air is not leaking out of the exhaust during high pressure conditions, the pump should be fine. Where you might see problems is when the pump is left idling with or without fluid inside.

When fluid is left in the pump, solids can settle or product can harden – as much as damage the diaphragm when the pump is restarted. If you are pumping a product that contains solids or can harden, it is beneficial to disassemble and clean the pump before restarting it. If your pump has been empty and idle for an extended period of time, you should inspect the diaphragm, balls, seats, and seals for cracks or deterioration due to heat and moisture.

CHOOSING A DOUBLE DIAPHRAGM PNEUMATIC PUMP MANUFACTURER

Like any piece of equipment, pump parts can fail prematurely if not operated correctly. To avoid unplanned downtime, be sure to choose a pump manufacturer that values ​​quality and offers exceptional technical guidance.

We offer a variety of tools and resources, including a chemistry guide, videos and more to support your pump from initial selection to troubleshooting and maintenance.
