The vacuum pump, also known as the vacuum pump, is a very practical tool in various industries that is used for different purposes. Vacuum pumps come in different models and features, each offered to the market by different brands and sellers. Pars Vacuum Industries has been active in this field for years as one of the top suppliers of vacuum pumps.

What is a vacuum pump?

A vacuum pump or vacuum pump is a device used to create a vacuum in various applications. The suction power of a vacuum pump indicates the amount of gas suction in cubic meters per hour. In fact, the work of a vacuum pump is to suck and discharge air molecules or various gases from an environment to create a vacuum reservoir with a pressure lower than atmospheric pressure.

Although the version used in those years was very primitive, its various attractions and efficiencies have led to the continuous growth and development of this device over the past three centuries. Today, these devices have more complexities compared to previous pumps.

Buying a vacuum pump

One of the important factors to consider when buying a vacuum pump is to pay attention to the external condition, capacity, and amount of negative pressure of the product. Neglecting any of these factors can lead to multiple problems in the long run.

Before any purchase of the above pumps, determine how much vacuum you need at a specific time, which will help in better selection of the device.

In general, you can receive the necessary assistance from the specialists of Pars Vacuum Industries before any purchase of the device.

Price review of vacuum pumps

Comparing different brands and prices of vacuum pumps is an action that should be done before purchasing. Given that this is an industrial product and its manufacturers and importers are very limited, we recommend that you definitely inquire about the price of vacuum pumps from large companies like Pars Vacuum Industries.

For this purpose, reputable companies generally accompany and guide you in all stages of purchase by providing catalogs with complete technical specifications and comprehensive reviews.

Technical specifications of vacuum pumps

The pump packages consist of one or more pumps, related electric motors, plus equipment that includes vacuum tanks, fluid and air separator shields, and on/off valves, etc., which can be used in various circuits.

Since the vacuum pumps produced by Pars Vacuum Industries are made from parts with various materials and suitable quality and high precision, the need for repairs has significantly decreased. The dynamic balancing of the rotors prevents any vibration in the devices, allowing customers to use them with peace of mind.

How does a vacuum pump work?

The rotational and eccentric movement of the rotor around the pump axis inside a cylinder containing service liquid, which is usually water (other fluids such as oils, organic fluids, and hydrocarbons can also be used), causes the formation of a liquid ring.

In the direction of rotation, with the continuous entry and exit of the blades inside the service liquid, the volume of the closed space between the two ends of the cylinder, both blades, and the inner wall of the liquid ring increases on one side (suction area), and suction occurs, while it decreases on the other side (discharge area), and compression takes place.

The cooling of the pump is done by the service liquid. Additionally, condensation of liquid particles along with the outgoing air and returning it to the pump can also be utilized, resulting in cooling the pump and stabilizing the temperature, allowing the compression to occur in an isothermal manner.

Applications of vacuum pumps

Considering the various types and models of vacuum pumps, their purchase should be informed and suitable for the intended application of the customer. For example, vacuum pumps used in air conditioners are used to remove moisture and then to remove air or non-condensable gases from the system. Keep in mind that the price of air conditioner pumps will vary based on their suction power and capacity.

Also, miniaturized vacuum pumps are lightweight and are used for medical operations and equipment. Buying small vacuum pumps in medical activities is cost-effective due to their importance and efficiency in these operations.

1. Applications of industrial vacuum pumps

Vacuum pumps have many industrial and scientific applications. These devices are generally used for the following:

Composite molding

Production of electric lamps

Semi-conductor processing

Electron microscopy

Photometry

Dairy equipment such as milking machines

Sewage systems

Waste compaction

Printing press

Glass and stone cutting

Cabinet making

Sugar and sweeteners

De-watering of paper pulp

Vacuum filtration

Flare Gas Recovery

Degassing under vacuum

Sanitary valves

Vacuum coating

Hospitals

Food industries

Automotive industries

Metal industries

Rubber and plastic industries

Vacuum casting

Pharmaceuticals

Laboratory vacuum pumps

And…

2. Laboratory vacuum pumps

Vacuum pumps in laboratories are also used for research purposes and conducting experiments that do not require oxygen and other gases.

Types of vacuum pumps

Various classifications can be considered for these types of pumps, which we will refer to below:

Based on pressure

Based on vacuum stages: There are two types of single-stage and two-stage pumps, with the two-stage type having a side plate valve and the single-stage type having a rotor chamber.

Based on structure: Water and oil blade vacuum pumps are two commonly used types in this classification. In water pumps, the responsibility of creating a vacuum is on the water, which creates a pressure difference in the closed space inside the cylinder by the rotation of the blades. These types of pumps are used in most industries and have high efficiency along with low maintenance costs.

Vacuum pumps have many types, and even more advanced models are still being manufactured. We will review six of the most important ones together.

1. Blade rotary vacuum pump

This pump is of the positive displacement type and includes several blades or vanes mounted on a rotor (rotating) that are located inside a chamber. The movement of the blades inside the chamber compresses the air and ultimately creates a vacuum.

2. Recirculating water vacuum pump

One of the most popular and widely used models of small powerful vacuum pumps used for transferring various gases and liquids is the recirculating water vacuum pump. This type of pump has various types such as single-blade, double-blade (where two blades act as two pumps), and water vacuum pumps with more than two blades. It is necessary to cover the inside of the pump chamber with a certain amount of water (slightly less than the center of the body) before starting operations.

In this model of pump, the power consumption is lower compared to other models, and its efficiency is higher. This device has low vibration, and due to its one-piece structure, the error rate is low. Other specifications of the water vacuum pump include its lack of need for internal lubrication. Additionally, its repair costs are economical, and considering its long lifespan, it is suitable. Also, due to the structure of this type of pump, its price varies widely.

3. Kinetic transfer pump

These pumps are also known as motion pumps that direct air from the inlet to their outlet. This creates a low-pressure area that gets trapped inside the chamber when it turns into a vacuum. Material transfer lines have many uses for these pumps.

Vacuum creation systems based on pressure range

Low vacuum: pressure up to 1 millimeter of mercury

Medium vacuum: pressure from 1 to 3-10 millimeters of mercury

High vacuum: pressure from 3-10 to 7-10 millimeters of mercury

Ultra-high vacuum: pressure from 7-10 to 11-10 millimeters of mercury

Infinite high vacuum: pressure less than 11-10 millimeters of mercury

Types of vacuum pumps used in various industries

Liquid ring pumps

Oil blade pumps

Piston pumps

Dry blade pumps

Oil pumps
