Q: What pumps are used for?
A: Chemical and petrochemical industry:Used for conveying chemicals and petrochemicals that are corrosive, flammable and explosive, viscous or contain solid particles.
Used for wastewater treatment, sludge transportation, chemical addition and wastewater recycling.
Q: How does a diaphragm pump work?
A: Diaphragm pumps realize liquid transportation through the reciprocating motion of flexible diaphragms. The process includes a drive mechanism that generates mechanical energy, reciprocating diaphragm motion that causes volume changes, and inlet and outlet valves that control the unidirectional flow of the fluid.
Q: Does a diaphragm pump experience fluid backflow?
A: A diaphragm pump effectively prevents backflow because the diaphragm creates a barrier between the liquid and the pump's moving mechanical parts.
Q: Is it bad to run a diaphragm pump empty?
A: Even though you can run diaphragm pumps dry, you should avoid . Every cycle a pump runs dry is one less cycle it will run to perform work. Running a PTFE diaphragm dry can cause premature failure.
Q: Diaphragm pumps are noisy?
A: Diaphragm pumps are quiet because valves are usually made of rubber.
Q: How long does a diaphragm pump last?
A: Standard operating conditions: Life range: typically 3 to 5 year.
Harsh working conditions:Lifespan range: may be shortened to 1 to 2 years.
Q: How long can diaphragm pumps run continuously?
A: Under normal operating conditions, such as flow rate and pressure not exceeding the rated parameters of the pump, and with regular maintenance, diaphragm pumps are capable of stable operation.
Q: What happens when a diaphragm pump dies?
A: The pump does not start at all or the motor does not run, which may be accompanied by motor heating or abnormal current. 2.The pump produces abnormal noise, vibration or heat during operation, a sudden drop in flow rate or pressure, and may have an abnormal sound or vibration. The pump motor or drive system is overheating, which may be accompanied by a burning odor or tripping of the motor protective device.
Q: Why use diaphragm pumps?
A: They are widely used in many industries such as chemical, pharmaceutical, food processing, mining, etc. due to their advantages of handling a wide range of liquids (including corrosive, highly viscous, and solid-containing liquids), good self-priming capability, adjustable flow rate and pressure, no lubrication requirements, high safety, and simple maintenance.
Q: Where are diaphragm pumps best suited?
A: Diaphragm pumps are better suited for pumping thicker liquids like sewage and mud. The most popular type of diaphragm pump uses compressed air as its power source, and the two chambers are a diaphragm, an outlet check valve, and a check valve for the inlet.
Q: How are diaphragm pumps inspected?
A: Inspect the pump, paying special attention to the body / manifold seals as well as the Diaphragm seals, for leaks. Once the inspection is complete slowly open the valve in the delivery pipework, the pump will start cycling again once the pressure in the delivery pipework drops. Turn off the air to stop the pump.
Q: How often do diaphragm pumps need to be replaced?
A: Just like the valves, the diaphragms in the backflow protectors can stretch and degrade over time, impacting suction. Replace these every 2 to 3 months if you pump once a day, and replace every 6 to 8 weeks if you pump more frequently.
