AODD Pumps, or Air-Operated Double Diaphragm Pumps, are widely used in many industries for their ability to handle a wide range of fluids, including corrosive and abrasive ones, without damaging the pump or contaminating the fluid. However, pumps can develop problems over time, like any mechanical device.
Pumps offered by the best AODD Pump Manufacturers in India are positive displacement pumps that use compressed air to operate the diaphragms. The pump consists of two diaphragms that are connected by a common shaft. When compressed air is applied to Common Problems with AODD Pumps.
Air Leaking of the pumps:
One side of the diaphragm, it flexes and forces the fluid out of the pump. At the same time, the opposite diaphragm is pulled back, creating a vacuum that allows the fluid to enter the pump. AODD pumps are known for their simplicity, reliability, and ability to handle a wide range of fluids.
Air leaks are one of the most common problems with pumps. Worn or damaged diaphragms, worn or damaged check valves, or improper installation can cause them. Air leaks can cause the pump to lose its prime or cavitate, leading to reduced flow rates or complete pump failure.
Failure of the Diaphragm:
Diaphragm failure is another common problem with pumps. Diaphragms can fail for various reasons, including excessive pressure, abrasion, or chemical attack. Diaphragm failure can cause leaks or reduced flow rates and contaminate the pumped fluid.
Faulty flow rates
Various factors, including worn or damaged diaphragms, worn or damaged check valves, or insufficient air pressure can cause low flow rates. Low flow rates can lead to reduced productivity and increased downtime.
Overheating is a major problem:
Overheating is a problem that can occur when AODD pumps are operated at high temperatures or with fluids that are too dense. Overheating can cause the diaphragms to fail or other components to become damaged. Overheating can lead to reduced pump life and increased downtime.
How to Overcome The Problems Of AODD Pumps
Check for Air Leaks:
To troubleshoot air leaks, it is important to check all fittings and connections for leaks, inspect the diaphragms, and check valves for signs of wear or damage. If air leaks are detected, the damaged components should be replaced, and the pump should be reassembled and tested for proper operation.
Replace Worn or Damaged Diaphragms:
To prevent diaphragm failure, inspecting the diaphragms regularly for signs of wear or damage is important. If worn or damaged diaphragms are detected, they should be replaced immediately to prevent leaks and reduce downtime.
Adjust Air Pressure:
If the pump is experiencing low flow rates, it may be due to insufficient air pressure. It is important to adjust the air pressure to the recommended level for the pumped fluid to ensure optimal flow rates.
Install a Heat Exchanger:
To prevent overheating, a heat exchanger can be installed to cool the compressed air before it enters the pump. This will help prevent the diaphragms from overheating and extend the pump’s life.
Conclusion:
AODD Pumps are widely used in many industries for their ability to handle a wide range of fluids and their simplicity and reliability. However, AODD pumps can develop problems over time, like any mechanical device. To troubleshoot and fix the most common problems with AODD pumps, it is important to inspect the pump for signs of wear or damage regularly, check for air leaks, adjust air pressure as needed, and install a heat exchanger if necessary.
These steps allow pumps to be maintained and kept running at peak performance, reducing downtime and increasing productivity. It is also important to follow the manufacturer’s recommended maintenance schedule and to use genuine replacement parts to ensure optimal pump performance and longevity. Pumps by leading Aodd Pump Suppliers in India like Nirmal Pumps can provide reliable and efficient fluid transfer for many years with proper maintenance and care.
