One of the main pumps used to transport water and other liquids is the piston pump.
Piston pumps are one of the oldest types of equipment used when high pressure or head is required for pumping. This pump was originally designed as a piston vacuum pump, and in later years, a more advanced version was produced called a plunger pump. This type of pump is available in a variety of sizes, including small and large piston pumps, and is offered by different brands.
Imen Datis Asia Technical and Engineering Company is one of the top providers of fire alarm and extinguishing equipment, all types of fire fighting and water supply pumps, etc. in the country, with the aim of increasing safety and protecting people’s lives and property.
Piston pumps, which fall into the category of positive displacement pumps, are also known by other names such as plunger pumps, high-pressure pumps, and car wash piston pumps. Since these pumps are suitable for hydraulic systems, they are also called hydraulic piston-pumps. In addition, gear pumps also fall into the category of hydraulic and positive displacement. However, while they are similar to piston-pumps, they also have some differences.
These pumps have a moving piston that moves up and down in a reciprocating motion. As the piston moves up, the outlet valve closes and the inlet valve opens, which creates suction and fluid enters the pump. Then, as the piston moves down, the inlet valve closes and the outlet valve opens, which removes fluid from the pump. This reciprocating motion of the pump components is similar to the operation of diaphragm pumps.
These pumps are divided into two types: direct and workshop, which is divided based on the type of connection of the electric motor to the pump. In workshop piston pumps, the connection is made in the form of a coupling with the electric motor, and this type of pump has lower efficiency and life expectancy compared to the direct connection model. However, the price of the workshop piston pump is lower than the direct connection model.
Based on how they operate and transfer fluid within the cylinder, piston pumps available on the market are divided into four main categories: Lift Piston Pump, Force Piston Pump, Axial Piston Pump, and Radial Piston Pump.
In terms of industrial application, these pumps are classified into three groups: car wash pumps, fogging pumps, and pesticide sprayer pumps (behind tractors).
In the lift type of piston pumps, a piston is placed inside the cylinder which, in addition to controlling the device, helps open the inlet valve and moves the fluid upwards. After the fluid is transferred, the piston returns to its original position and this process is repeated continuously.
In the force type, the movement of the piston from the top of the cylinder downwards directs the working fluid towards the cylindrical inlet valve. Then, by creating high pressure by the piston, the fluid level inside the cylinder is compressed downwards and finally moved towards the outlet valve, completing the pumping process. This model of pump is less used compared to the lift type.

Axial piston pumps are one of the most widely used types in vehicle air conditioning systems, hydraulic motors, and self-contained pumps. In this type, several pistons are individually arranged in independent cylinders in a row on a specific circular circumference. The reciprocating motion of these pistons in parallel and coaxially displaces the working fluid and performs the pumping process.
Radial piston pumps are used when high efficiency, high pressure, low pumping flow, and a uniform, undistorted flow at the outlet are desired. The operation of this type of pump is similar to that of an axial pump, but its cylinders are arranged concentrically and opposite each other on a circle. The movement of the pistons inside the cylinders is done sequentially.
The most important applications of this type of pump include fogging, spraying pesticides, and washing cars, machines, and tables. In addition, this pump is also used in the following industries:

Pumps are one of the key tools in industry that play a fundamental role in facilitating various processes. These equipments significantly increase the efficiency and productivity in industrial operations by transferring fluids from one point to another. Pumps save time and money by reducing the need for manpower and increasing the speed of fluid movement.
Important applications of pumps include water transfer in irrigation systems, chemical handling in refineries, fuel supply in the oil and gas industries, and cooling of industrial machinery. Pumps also play a vital role in water and wastewater treatment systems for the transfer and processing of fluids.
In addition to making things easier, pumps help improve the quality of end products and increase safety in industrial processes by reducing human errors and improving the accuracy of fluid transfer. Therefore, these equipments have a special place as one of the essential tools in various industries.

One of the most important points in installing piston pumps is the correct placement of the fluid on the pump. If this condition is not met, it may lead to a decrease in the pressure of the car wash pump and disrupt its performance. Installing piston or car wash pumps is not a complicated process, but paying attention to some principles during installation can help improve the performance and efficiency of the pump.
Piston pumps are distinguished from other industrial pumps due to their special structure and design. In general, the most important components of piston pumps include the following:
