The working principle of solid vacuum pump is mainly powered by compressed air, using vacuum suction loading and pneumatic positive pressure to convey materials. Crown's solid vacuum pumps are powered entirely by compressed air and are capable of conveying solid particles, powdered materials, slurries, highly concentrated sludge, oil-containing sludge, mineral slurries, and other bulk materials, etc.

The working principle of solid vacuum pump can be divided into the following steps:

Suction process: In the suction process, the volume inside the pump chamber increases, forming a low-pressure area, making the external solid material is sucked into the pump chamber.
Compression process: as the pump chamber volume decreases, the material is compressed, the pressure gradually increases.
Exhaust process: when the pressure in the pump chamber reaches a certain level, the material is discharged out of the pump through the exhaust port, completing a working cycle.


The main application areas of solid vacuum pumps include:

Conveying solid particles and powder materials: it is suitable for conveying all kinds of solid particles and powder materials, such as mineral slurry and high concentration sludge.
Environmental protection field: in sewage treatment and sludge treatment, solid vacuum pumps can effectively transport oily sludge and other bulk materials.
Industrial production: in the production process of chemical, food, pharmaceutical and other industries, solid vacuum pumps are used for material conveying and loading to improve production efficiency

1. Polishing of the inner surface of the drum and the drum: this treatment process greatly reduces the residue of the material during the centrifugation process, helps to avoid cross-contamination and ensures the purity and safety of the product. The polished surfaces are smoother and easier to clean, meeting the stringent requirements of food-grade equipment.

2. Temperature and vibration sensors: The equipment's built-in temperature and vibration sensors enable real-time monitoring of key parameters during the centrifugation process. Temperature monitoring helps prevent overheating from damaging the material or the machine itself, while vibration monitoring can detect and prevent potential operational failures, ensuring stable equipment operation and improving productivity and product quality.

3. Automatic Lubrication System: This system automatically provides the right amount of lubricant to key components, reducing wear and prolonging equipment life. At the same time, the automated operation also reduces manual intervention and improves production safety and efficiency.

4. Stainless steel control cabinet: The control cabinet made of stainless steel has good corrosion resistance and easy cleaning, which is able to resist the erosion of chemicals commonly found in food processing environments, and ensure the long-term stable operation of the control system.

5. VFD (Variable Frequency Drive) and PLC (Programmable Logic Controller) overload protection: The VFD enables precise control of the motor speed, improving energy efficiency and reducing energy consumption, while the PLC is responsible for the logical control of the entire centrifugal process, including safety functions such as overload protection. This combination not only improves the intelligent level of the equipment, but also enhances the safety and reliability of the equipment.

6. Hydraulic system is selected from the internationally renowned Swiss brand Viscotherm: Viscotherm, as a famous brand of hydraulic system, is famous for its high quality, high stability and long life. The selection of this brand of hydraulic system ensures the stability and reliability of the centrifuge under high-pressure, high-speed operation, and further improves the overall performance of the equipment.

Sludge vacuum pump, also known as solids transfer pump or drill cuttings transfer pump, is a pneumatic vacuum transfer pump with high load and strong suction. It creates a vacuum pneumatically for suction and then converts to positive pressure for material discharge. The unique design of this pump, with no rotating parts in the chamber, allows it to operate in the toughest environments with low maintenance and to transport materials with more than 80% solids and high specific gravity materials at high speed. The sludge vacuum pump has the following features:

High-efficiency venturi unit generates vacuum up to 25 inches HG (mercury column), equivalent to 85 kPa, with virtually no wear parts in the presence of strong air flow.
Compact pump body for conveying distances up to 500-1000 metres.
Commonly used for a wide range of applications such as drilling cuttings conveying, oily sludge conveying, tank emptying operations, waste pumping over long distances, as well as mineral and waste conveying.


The advantages of sludge vacuum pump include:

High self-priming capacity and long conveying distances, with suction distances of up to 50 metres and discharge distances of 500-1000 metres.
Wide range of materials that can be used for conveying, from liquids, mixed liquids to solids.
The maximum particle size of solid materials that can be conveyed is 50mm or 75mm, and the solid content of mixed liquid can be conveyed up to 80%.
Pneumatic work, without power supply, can meet the requirements of explosion-proof area.
No rotating parts in the chamber, not easy to wear and tear, long service life.
Can work automatically and continuously, easy to operate and maintain.
Compact structure, easy to move.
The technical parameters of sludge vacuum pumps include maximum conveying capacity, inlet and outlet diameters, vacuum degree, maximum suction distance and maximum discharge distance of different models, which can meet the sludge treatment requirements of different industries.

GN is showing the following equipments

GN decanter centrifuge 

GN decanter centrifuge has been widely used as a sludge dewatering centrifuge. With the ability to effectively separate water from sewage sludge, this machine greatly reduces the amount of waste to be disposed of, thereby lowering transport costs and making sludge disposal easier and more environmentally friendly. By increasing sludge dryness, it also promotes energy recovery through anaerobic digestion, contributing to the circular economy of sewage treatment plants.

GN solid vacuum pump is a high-performance and compact device that can generate a vacuum degree of up to 25 inches of mercury. The suction generated by vacuum allows the garnet powder to be effectively sucked into the equipment, and then discharged and transported to the designated location through positive pressure.

Sludge vacuum pump, also known as solids vacuum pump or solids transfer pump, is a high load and powerful suction pneumatic vacuum pump. It is a vacuum pump that forms vacuum through gas movement for suction, and then converts it into pressure for material discharge. It can pump solid, powder, liquid and solid-liquid mixtures and many other different materials. There are no rotating parts in its cavity, which enables it to work in the most difficult environment, and it can transport more than 80% of the solid phase at high speed.

The characteristic of this device is its completely pneumatic operation mode, 100% air driving, which does not require electric power connection, so it can be safely used in areas with strict explosion-proof requirements.
