What is a Piston Pump?

Piston pumps are sturdy and simple devices. These pumps consist of a chamber, a piston, and several control devices. They work by reducing the medium in the manual pump by flowing into the chamber. When the air pressure exceeds the pressure that opens the valve spring, the reduced medium can be transported through the open outlet valve. When the piston is pulled back, it releases the inlet valve and closes the outlet valve, allowing suction to be used to compress additional medium.

Learn about piston pumps

Piston pumps can be defined as positive displacement pumps. These pumps use a piston, diaphragm, or plunger to move liquids. These pumps use check valves as input and output valves. A typical piston pump is a rotary pump that uses a wheel or rotating shaft to operate the piston. The rotating part can be connected to the shaft from the center, and the shaft can be connected to the piston. When the rotating part twists, it causes the shaft and piston to move down to pull it back.

Piston pumps are used to power heavy and small machines, just like hydraulic pumps. The applications of piston pumps mainly include conveying paints, pastries, chocolates, etc. The size of these pipelines has increased for industrial use. All types of piston pumps in radial and axial forms are also used for advanced industrial applications, many of which are arranged in circular cylinders. These piston pumps are divided into different types, namely lifting pumps, forcing pumps, axial pumps, and radial plungers pumps. Among these pumps, lifting and forcing pumps can be manually operated with the help of the engine.

How piston pumps work?

The working principle of piston pumps is similar to PD pumps because they work with the help of the pumping mechanism to increase the volume of the liquid. These pumps can use electrical power from the power supply. These pumps include one or more pistons with a set of control devices. Double-acting pumps include two pistons and two control devices. Similarly, three-cylinder pumps include three pistons and three control devices. It is crucial to check the control devices on both sides to ensure the flow direction of the fluid on both sides.

These piston pumps are single-acting or double-acting pumps. Double-acting pumps include two sets of control devices and liquid at both ends. This allows the pump to complete a pumping cycle by flowing in one direction to the other. When the piston moves forward in one direction, it exhausts from the other side. The pump requires a single-action version to flow in two directions to complete a cycle.
