Product Description
Working principle
The vacuum in dry screw pumps is created through 2 parallel-arranged screw rotors that rotate in opposite directions. These rotors trap the gas coming in through the inlet and deliver it to the gas discharge or pressure side. As the gas is getting compressed, there is no contact between the rotors. This does away with any need for the compression chamber to have any operating fluids or lubrication.
The lubricant used to lubricate the gears and shaft seal is sealed in the gearbox by the shaft seal. The pump can be cooled either directly by circulating cooling water or by a cooling unit with fan and radiator.

3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects by depositing successive layers of material. Vacuum pumps are utilized in various aspects of 3D printing to enhance the overall quality, accuracy, and reliability of printed parts. Here are some key ways in which vacuum pumps impact 3D printing:
1. Material Handling and Filtration: Vacuum pumps are used in 3D printing systems to handle and control the flow of materials. They create the necessary suction force to transport powdered materials, such as polymers or metal powders, from storage containers to the printing chamber. Vacuum systems also assist in filtering and removing unwanted particles or impurities from the material, ensuring the purity and consistency of the feedstock. This helps to prevent clogging or contamination issues during the printing process.
2. Build Plate Adhesion: Proper adhesion of the printed object to the build plate is crucial for achieving dimensional accuracy and preventing warping or detachment during the printing process.

What Is the Difference Between Dry and Wet Vacuum Pumps?
Dry and wet vacuum pumps are two distinct types of pumps that differ in their operating principles and applications. Here’s a detailed explanation of the differences between them:
Dry Vacuum Pumps:
Dry vacuum pumps operate without the use of any lubricating fluid or sealing water in the pumping chamber. They rely on non-contact mechanisms to create a vacuum. Some common types of dry vacuum pumps include:
1. Rotary Vane Pumps: Rotary vane pumps consist of a rotor with vanes that slide in and out of slots in the rotor. The rotation of the rotor creates chambers that expand and contract, allowing the gas to be pumped. The vanes and the housing are designed to create a seal, preventing gas from flowing back into the pump. Rotary vane pumps are commonly used in laboratories, medical applications, and industrial processes where a medium vacuum level is required.
2. Dry Screw Pumps: Dry screw pumps use two or more intermeshing screws to compress and transport gas. As the screws rotate, the gas is trapped between the threads and transported from the suction side to the discharge side. Dry screw pumps are known for their high pumping speeds, low noise levels, and ability to handle various gases. They are used in applications such as semiconductor manufacturing, chemical processing, and vacuum distillation.
3. Claw Pumps: Claw pumps use two rotors with claw-shaped lobes that rotate in opposite directions. The rotation creates a series of expanding and contracting chambers, enabling gas capture and pumping. Claw pumps are known for their oil-free operation, high pumping speeds, and suitability for handling dry and clean gases. They are commonly used in applications such as automotive manufacturing, food packaging, and environmental technology.
Wet Vacuum Pumps:
Wet vacuum pumps, also known as liquid ring pumps, operate by using a liquid, typically water, to create a seal and generate a vacuum. The liquid ring serves as both the sealing medium and the working fluid. Wet vacuum pumps are commonly used in applications where a higher level of vacuum is required or when handling corrosive gases. Some key features of wet vacuum pumps include:
1. Liquid Ring Pumps: Liquid ring pumps feature an impeller with blades that rotate eccentrically within a cylindrical casing. As the impeller rotates, the liquid forms a ring against the casing due to centrifugal force. The liquid ring creates a seal, and as the impeller spins, the volume of the gas chamber decreases, leading to the compression and discharge of gas. Liquid ring pumps are known for their ability to handle wet and corrosive gases, making them suitable for applications such as chemical processing, oil refining, and wastewater treatment.
2. Water Jet Pumps: Water jet pumps utilize a jet of high-velocity water to create a vacuum. The water jet entrains gases, and the mixture is then separated in a venturi section, where the water is recirculated, and the gases are discharged. Water jet pumps are commonly used in laboratories and applications where a moderate vacuum level is required.
The main differences between dry and wet vacuum pumps can be summarized as follows:
1. Operating Principle: Dry vacuum pumps operate without the need for any sealing fluid, while wet vacuum pumps utilize a liquid ring or water as a sealing and working medium.
2. Lubrication: Dry vacuum pumps do not require lubrication since there is no contact between moving parts, whereas wet vacuum pumps require the presence of a liquid for sealing and lubrication.
3. Applications: Dry vacuum pumps are suitable for applications where a medium vacuum level is required, and oil-free operation is desired. They are commonly used in laboratories, medical settings, and various industrial processes. Wet vacuum pumps, on the other hand, are used when a higher vacuum level is needed or when handling corrosive gases. They find applications in chemical processing, oil refining, and wastewater treatment, among others.
It’s important to note that the selection of a vacuum pump depends on specific requirements such as desired vacuum level, gas compatibility, operating conditions, and the nature of the application.
In summary, the primary distinction between dry and wet vacuum pumps lies in their operating principles, lubrication requirements, and applications. Dry vacuum pumps operate without any lubricating fluid, while wet vacuum pumps rely on a liquid ring or water for sealing and lubrication. The choice between dry and wet vacuum pumps depends on the specific needs of the application and the desired vacuum level.
How Do You Choose the Right Size Vacuum Pump for a Specific Application?
Choosing the right size vacuum pump for a specific application involves considering several factors to ensure optimal performance and efficiency. Here’s a detailed explanation:
1. Required Vacuum Level: The first consideration is the desired vacuum level for your application. Different applications have varying vacuum level requirements, ranging from low vacuum to high vacuum or even ultra-high vacuum. Determine the specific vacuum level needed, such as microns of mercury (mmHg) or pascals (Pa), and choose a vacuum pump capable of achieving and maintaining that level.
2. Pumping Speed: The pumping speed, also known as the displacement or flow rate, is the volume of gas a vacuum pump can remove from a system per unit of time. It is typically expressed in liters per second (L/s) or cubic feet per minute (CFM). Consider the required pumping speed for your application, which depends on factors such as the volume of the system, the gas load, and the desired evacuation time.
3. Gas Load and Composition: The type and composition of the gas or vapor being pumped play a significant role in selecting the right vacuum pump. Different pumps have varying capabilities and compatibilities with specific gases. Some pumps may be suitable for pumping only non-reactive gases, while others can handle corrosive gases or vapors. Consider the gas load and its potential impact on the pump’s performance and materials of construction.
4. Backing Pump Requirements: In some applications, a vacuum pump may require a backing pump to reach and maintain the desired vacuum level. A backing pump provides a rough vacuum, which is then further processed by the primary vacuum pump. Consider whether your application requires a backing pump and ensure compatibility and proper sizing between the primary pump and the backing pump.
5. System Leakage: Evaluate the potential leakage in your system. If your system has significant leakage, you may need a vacuum pump with a higher pumping speed to compensate for the continuous influx of gas. Additionally, consider the impact of leakage on the required vacuum level and the pump’s ability to maintain it.
6. Power Requirements and Operating Cost: Consider the power requirements of the vacuum pump and ensure that your facility can provide the necessary electrical supply. Additionally, assess the operating cost, including energy consumption and maintenance requirements, to choose a pump that aligns with your budget and operational considerations.
7. Size and Space Constraints: Take into account the physical size of the vacuum pump and whether it can fit within the available space in your facility. Consider factors such as pump dimensions, weight, and the need for any additional accessories or support equipment.
8. Manufacturer’s Recommendations and Expert Advice: Consult the manufacturer’s specifications, guidelines, and recommendations for selecting the right pump for your specific application. Additionally, seek expert advice from vacuum pump specialists or engineers who can provide insights based on their experience and knowledge.
By considering these factors and evaluating the specific requirements of your application, you can select the right size vacuum pump that meets the desired vacuum level, pumping speed, gas compatibility, and other essential criteria. Choosing the appropriate vacuum pump ensures efficient operation, optimal performance, and longevity for your application.

Merchandise Description
Acuum pump for engraving equipment
The 2BV sequence vacuum pump is an upgraded product primarily based on the conventional vacuum pump in CZPT , which adopts new engineering. It adopts the coaxial immediate relationship design of the equipment and the pump, which is hugely reliable, simple to put in and sustain, and has a volume of 30% less than the conventional vacuum pump. It operates smoothly, has a sounds of significantly less than 62 decibels, has self-priming capability, and is straightforward to operate. Since of the use of mechanical seals, leakage is removed. 50% of the operating fluid of the steam-drinking water separator geared up with the pump can be recycled, which lowers air pollution and decreases functioning fees. The pump uses a bronze impeller to boost the corrosion resistance of the pump. In accordance to consumer demands, making use of stainless steel, the pump will function typically in severe environments. For that reason, it is broadly used in chemical, pharmaceutical, food, paper and metal industries.
The rotating part of 2BV, the impeller, rotates to make the operating fluid sort a liquid ring in the oval pump. At this time, the working fluid acts as a sealing medium, a compression medium and a cooling medium at the very same time. There is no dress in and no lubrication. Because the impeller is eccentric relative to the rotating liquid ring. The liquid reciprocates in the space among the blades, which sucks and compresses the pumped medium just like the motion of a piston in a cylinder. In the exhaust section, the liquid ring steadily moves away from the wheel tyres, expelling the pumped medium from the exhaust port in the axial path. In the suction stage, the impeller slowly moves away from the wheel tyres, sucking the pumped medium in the axial direction from the suction port. Steady injection of supplementary liquid to compensate for the liquid carried absent by the exhaust gas.
All the style characteristics of the 2BV sequence make it basically routine maintenance-free. one hundred%, oil-free of charge layout, no want to use oil, and of training course no need to replace oil filtering tools. Under normal use, the bearings only need to have to be greased after every single 5 years on regular. Beneath normal working conditions, 2BV mechanical seals do not want to be modified routinely like packing seals.
