A piston pump necessarily comprises of a piston, a cylinder and a connecting rod that is attached to the piston, which moves inside the cylinder. Such plumps are used for transmission of fluids and compression of gases for different industrial applications.
Primarily there are two kinds of piston pumps. One is used for handling fluids and is called a hydraulic pump; whereas the other is employed for transmission or compression of gases and called as pneumatic pumps. So, the choice depends whether you need to handle liquids or gases and air. Piston pumps have better priming qualities, but they do have some limitations too. Here are some of those:
These can’t operate under high pressure and their shelf life is shorter. In their case, flow performance curve is inherently flat and are not suitable for, for moving explosive or toxic materials.
While using these pumps for industrial applications it’s important to maintain constant flow of liquids, meaning the volume of liquid that is fed into the system must remain equal to the volume that is thrown out or pumped out. Depending on its design and requirements, a piston pump may have one piston or many parallel pistons.
The most common application of piston pumps is for metering of low flow rate fluids kept at reserved pressure in labs and chemical processing plants. For appropriate functioning, the stroke of its piston needs adjustment as per the requirements of the user.
The best way of procuring a pump to suit your requirements is to look for it online. That’s because most of the reputed manufactures and their distributors have their websites catering to a vast variety of customers around the world.
Online ordering of such pumps or another pump for that matter, like triplex plunger or pressure pumps is convenient and save a lot of time. If you happen to be in car-washing business, you may order a car wash pump too online without having to go out and spending a lot of time visiting one dealer and the other. Using the Internet also allows you to offer servicing facilities in such a business.
