Air-operated double-diaphragm pumps are known for their reliability, but even the best pumps can fail without routine maintenance. Here’s how to extend their lifespan and ensure optimal performance.
Like any piece of equipment, air-operated double-diaphragm (AODD) pumps need routine maintenance and repair to ensure long-term durability.
Correct maintenance is essential for ensuring the efficient and reliable working of a diaphragm pump.
Key factors to consider for preventative maintenance are:
- Diaphragm lifetime
- Compressed air quality
- Flushing of pumps after use.
How to maintain a diaphragm pump:
- Check the diaphragms regularly: Diaphragms are the most critical component of a diaphragm pump and can wear out over time. Check them regularly for signs of wear or damage and replace them as needed.
- Inspect valves: Valves are also important components of a diaphragm pump. Inspect them regularly for signs of wear, corrosion, or other damage. Replace any faulty valves as soon as possible!
- Check the fluid inlet and outlet: Check the fluid inlet and outlet regularly for signs of clogs or other obstructions. Clean them out as needed to ensure proper fluid flow.
- Lubricate moving parts: Diaphragm pumps have several moving parts, such as the air motor and the valve mechanism. Lubricate these parts regularly to prevent friction and wear.
- Check air supply: Diaphragm pumps operate on compressed air. Check the air supply regularly to ensure the pump receives adequate air pressure and volume.
- Inspect fittings and connections: Check the pump’s fittings and connections regularly for signs of leaks or damage. Tighten or replace any faulty fittings as needed.
- Clean the pump: Clean the pump regularly to prevent the build-up of dirt, debris, or other contaminants that can interfere with the pump’s performance.
Maintaining your AODD pump often starts with choosing the right pump for the right application at the beginning. Consult a knowledgeable pump supplier such as Kelair Pumps to discuss your pumping requirements.
