subject: Reference Points To Help You Know The Pros And Cons Of Piston Pumps [print this page] Piston pumps have proven to be tremendously useful when it comes to tasks such as moving liquids and gases. This has made them one of the most commonly used pumps in industrial as well as domestic set-ups. If these pumps are used for displacing or transferring liquids, they are known as hydraulic pumps and if they are used to move gases, they are classified as pneumatic pumps.
While these pumps are widely used, they often require some amount of maintenance; especially if they are being used for materials under high pressure. In such a pump, the packing is attached to the piston rod which moves inside a cylindrical surface that has a smooth inner wall. These pumps are often used in municipal corporation, laboratories, water-supply centers, buildings and other such places. Depending on the gas or liquid to be transferred, the stroke rate of these pumps can be altered to suit specific requirements.
Scientifically speaking, these pumps incorporate the reciprocating motion to move liquids or gases. For instance, when reciprocating motion is created along an axis, it builds pressure inside the cylinder. This pressure is what forces the liquid or gas out of the barrel.
*What are the integral components of piston pumps?
Seals are among the most central component of such a pump. They help separate the material being pumped from the power fluid. Since the components housed inside the piston pump often undergo a lot of wear and tear, they are available in different materials depending on where the pump is to be used. These components could be crafted out of metals such as bronze, brass, iron, nickel, steel or stainless steel. For instance, pumps where caustic materials are to be transferred might make use of stainless steel components because this metal shows good corrosion resistance.
In addition to these pumps, misting pumps are also widely used in various types of applications. These pumps pressurize a liquid and create a mist which helps in cleaning or coating tasks. For instance, in a car wash shop, you might have spotted a mist pump being used to wash your car with a jet of water.
Over all, pumps with operate under pressure, such as misting pumps, require regular maintenance and some caution in use. Hence, it is advisable to read the users manual carefully and place orders only with a reputed manufacturer.
At the same time, it is important to note that regular piston pumps often have a series of performance and maintenance related problems. For instance, these pumps might stall when exposed to high pressure. They also often have a shorter shelf life and show a flat performance curve. At all times, it must be remembered that these pumps are often unsuitable for transferring explosive materials or toxic materials. You can avoid facing these problems if you order your piston pumps only from a good quality manufacturer.
