The claw vacuum pump, with no lubricant or sealing fluid in the overflow section and capable of condensing and recovering condensable gases, solves potential contamination issues caused by steam jet pumps, scroll pumps, and liquid ring pumps to containers and the environment. This ensures product quality for the users, and the recovered materials can significantly enhance economic benefits. Thanks to the maintenance-free design, it also resolves the hassle of maintaining other vacuum pumps, saving users a substantial amount of maintenance costs.

The working principle of claw-type vacuum pumps

The claw-type vacuum pump features several interlocking claw-shaped rotors within the pump chamber. There is no contact between the rotors and no contact between the rotors and the pump chamber, leaving minimal gaps. No lubricants are required, ensuring a clean vacuum environment. The pump structure employs a multi-stage interlocked rotor design, with each set of rotors located in different pump chambers and moving in sync in opposite directions. The pump chamber is divided into an intake chamber and an exhaust chamber by the claw-shaped rotors. As the rotors continuously operate, they cycle through an intake and exhaust process, achieving the purpose of continuous pumping.

Advantages of claw vacuum pumps

1. The greatest advantage is energy conservation, environmental protection, and emission reduction. Replacing steam jet pumps, it achieves an effective energy-saving rate of over 85% and emits no wastewater.

2. Strongly capable of extracting condensable gases, including pure solvent gases, enabling gas-liquid separation, precise分流，and recycling; truly capable of extensive drainage, and can be drained while the equipment is in normal operation.

3. Achieve a clean vacuum environment. This effectively enhances production efficiency and improves product quality. The sealing form, composed of skeletal sealing, mechanical sealing, and special sealing, ensures a safe isolation between the pump chamber and the oil tank.

4. Wide vacuum range (105-10-1), capable of atmospheric startup, continuous direct suction and exhaust of air, and adjustable vacuum level according to the user's process environment.

5. Variable frequency drive and DCS control, flexible start-up, minimal whole machine shock, and long service life.

6. This pump features a non-disassembly cleaning function. In the event of large amounts of dust, sticky substances, or other foreign matter during operation, a half-hour cleaning inside the pump will meet the factory's requirements, ensuring stable operation.

7. Offer a variety of material options based on different operating conditions.

Bearing material: Gray iron, cast steel, stainless steel

Rotor Material: Carbon Steel Corrosion Treatment

Spindle Material: 40Cr, 2Cr13

Fully meets the requirements for use in the most severe environments.

8. Wide application range, capable of meeting the requirements of all production processes in the petrochemical, pharmaceutical, electronic, aerospace, nuclear, and laboratory industries. Fully compatible with molecular pumps and Roots blowers to form vacuum systems.

9. This pump can truly achieve large-scale drainage and can drain while operating normally in actual work.

10. A record of 16,000 hours of continuous, trouble-free operation, ensuring stable and reliable quality. Maintenance-free design with low operating costs.
