3 Frequently Asked Questions about pulsation dampeners


If you have got an Air operated double diaphragm pump in your system, odds are you might be experiencing some sort of pulsation resulting in the rattling & vibration movement in the pipes and system? A pulsation dampener may be a great choice for AODD pump to get a steady flow.

WHAT DOES A PULSATION DAMPENER DO?
Pulsation dampeners absorb the power from the pulse wave created by a diaphragm pump, more like a twitch absorber in a vehicle. Absorbing these pulse waves protects pipe welds and supports the system components from damage due to emphasis or excess movement.

HOW DOES A PULSATION DAMPENER WORK?
As the pulsating flow enters the dampener vessel, the air pocket trapped above the fluid absorbs up to 80% - 89% of the pulsation, allowing a laminar or smooth flow downstream the dampener.

A pulsation dampener is a device that stores energy & it has a pre-set charge that it can use to absorb shocks to the system on which it is installed. This subtracts shocks can aid systems, especially piping systems, in dealing with pulses, vibrations, water hammering & fluctuations in pressure levels. This process can help develop the longevity of the equipment in the system.

WHERE ARE PULSATION DAMPENERS COMMONLY USED?
Pulsation dampeners are commonly used anywhere an diaphragm pump discharges flow in an unsteady manner, and where the pulsation may result in damage to the piping system. Diaphragm pumps typically advantages from a pulsation dampener. The different types of pulsation dampener used are typically defined by where they are placed in the system, and what they need to do.

For example, "pulsation dampeners" are placed on the discharge of the pump, "inlet stabilizers" are on placed before suctioning of the pump, & an accumulator or "surge suppressor" is used next to a valve or other devices that brake the flow in a system.

HOW DOES AODD PUMP WORKS ?

AODD pumps are important, durable, protean, and able of handling nearly any process fluid, from water to thick, unpredictable, and indeed dangerous liquids when duly applied. Then's a introductory manual on AODD pumps and how they serve. An air-operated double-diaphragm pump is a positive relegation pump that utilizes compressed air by acting on a brace of repaying elastomeric diaphragms that alternatively “ pull and push” fluids or flowable maquillages through a stopcock system/ pumping chambers and out of the pump’s discharge. Also see : Best Aodd pump suppliers in india It transports fluid using two diaphragms, each separating the motive air from the fluid being pumped. Each diaphragm has its own pump chamber where it generates expanding and contracting depressions of fixed volume relegation. The rate is determined by the speed of the pump’s integral air stopcock medium delivering and exhausting air from the air chambers that fill and clear the depressions. Also read : Best A...

Benefits of Air Operated Double Diaphragm Pumps

Understanding the Benefits and Applications of Air Operated Double Diaphragm Pumps An air operated double diaphragm pump (AODD) is a type of positive displacement pump that uses compressed air as the source of energy to move liquids. It consists of two flexible diaphragms that separate the pumping chamber from the air inlet and outlet. The air pressure causes the diaphragms to expand and contract, creating suction and discharge strokes that move the liquid through the pump. One of the key benefits of AODD pumps is that they are self-priming and can operate in both wet and dry conditions. They are also capable of handling liquids with high viscosities and solids, making them suitable for a wide range of applications. Additionally, they are simple in design and require minimal maintenance, making them a cost-effective solution for many industrial applications. AODD pumps are commonly used in a variety of industries, including chemical, food and beverage, pharmaceutical, and water treat...
