High pressure piston pumps, main types

As the name suggests, the main components of this type of pump are a cylinder and a piston. All piston pumps operate on a similar principle. The mechanics of this type of pump are based on the piston compressing the liquid and building pressure in the cylinder. The maximum pressure generated by this type of pump depends on several factors:

• The density of the piston stroke in the cylinder;
• Piston stroke speed;
• Valve tightness when closed;
• Valve opening speed;
• Number of cylinders.

To achieve high performance, High pressure pump price The pump, which varies widely, is equipped with multiple piston assemblies. These units are capable of delivering high pumping rates and significant pressure readings.

Although the operating principle of a piston pump is virtually identical across all units, there is a significant diversity of engineering solutions. These solutions are designed to address different challenges, and this range of designs allows for precise selection of the unit for a specific component/fluid, or operating conditions and requirements. Equipment differences can be broadly categorized into several factors:

• Depending on the number of cylinders, there are one, two, three and four cylinder pumps;
• According to the type of piston, they are classified as piston or plunger;
• According to the maximum pressure generated, they are produced as low, medium and high pressure;
• According to the frequency of shaft revolutions, they are classified as high-speed, medium-speed and low-speed;
• According to the location of the piston axes, there are horizontal and vertical;
• Action multiplicity: single action (one working cavity is working) or double action, in which the piston works on both sides, thereby accelerating pumping without changing the number of revolutions.

Considering the above, it's possible to more accurately select pumping equipment for a specific task. For example, for a low-speed or low-torque engine, a gearbox (gear or belt-type) and a low-speed pump can be used. If high pressures aren't required in the line, there's no need to invest in expensive units. Instead, choose a pump that delivers the exact pressure and pumping speed required at the engine speed.
