The reciprocating pumps feature diaphragms or pistons to pump gases or fluids. The term reciprocating used to refer to them indicates their working mode namely continuous and repeated forward and backward motion. They can be described as positive displacement devices which are made to displace fluids or gasses with a moving object for transporting from one place to another or from one level to another. The piston reciprocating pumps bring about the pumping action by drawing the input liquid or gas alternatively into a piston cylinder through an inlet port and then it is expelled through the discharge port. The same can be achieved with a diaphragm set up too in place of the piston.

The reciprocal or continuously repeated forward and backward movement is the principal mechanism that these kinds of pumps invest in to achieve the desired output. The action noticed in these pumps is described as the cyclic action of the piston or diaphragm. The resulting mechanism is known as positive displacement meaning progressively conducting the moving fluid or gas within a closed space by way of introducing a moving obstruction namely either a diaphragm or a piston in their path. Similar to an internal combustion engine, a piston pump features a cylindrical arrangement.

Each of the cylinders is fitted with inlet and outlet valves that function in perfect coordination with the stroke of the piston. This cyclic process is repeated to result in a constant, uninterrupted flow of fluid or gas from the pump. The aspects that decide the output capacity of reciprocating pumps include the rotational speed, compression ratio, number of cylinders, capacity of the cylinders, etc. while piston reciprocating pumps are not suitable to pump explosive or toxic kind of fluids or gasses, the diaphragm kind of reciprocating pumps can serve this purpose.  

Though the uniform torque cannot be expected and there shall be a pulsating flow, reciprocating pumps have a lot of advantages. They are highly efficient than the other kind of pumps on account of their superior technology. They do not require any priming. You can depend on them to transport fluids at high pressure. They are ideally suitable to work in wide pressure range. Once you install them, you can expect a continuous ate of discharge. Therefore, you can bank on them for a variety of high end uses and applications.

Reciprocating pumps have a very long life. The changes in pressure and discharge cannot affect the performance. While these pumps can reach high pressure ranges, you can control the pressure without impacting the rate of flow. By designating the right kind of valves, you can apply these pumps under different scenarios for transporting viscous fluids, high volume solids and gasses and other kinds of challenging requirements. When compared to roller and centrifugal pumps, they do cost a bit higher since they feature advanced technology. They are highly suitable and the most sought after pumping solutions for the complete range of high end industries.
