VDP progressive cavity pumps
Company Name :
Shanghai Aifa Technology Co., Ltd.Brand :
AIFAFounded in 2009, Shanghai Aifa Technology Co., Ltd. is an enterprise integrating R&D, production, sales and after-sales service of dry vacuum pumps and vacuum solvent recovery systems, headquartered in Pudong New Area, Shanghai, the economic center.
The company has carried out in-depth cooperation with major domestic professional colleges and universities, professional chemical and pharmaceutical enterprises, and its products are jointly developed and designed with experts in chemical, pharmaceutical, environmental protection and other industries, and the equipment process, processing and manufacturing, performance and after-sales service are in the forefront of the domestic level.
1.DCP claw-type vacuum pump
Features:
① Verified through industry practice and proven over time.
② Specifically designed for chemical applications.
③ Carefully designed and tested to ensure safety and reliability.
④ Stable operation, even during process anomalies.
⑤ Low operating costs.
⑥ Easy to maintain, low power consumption, and does not require the injection of cooling gas.
2.VDP Screw Vacuum Pump
Features:
① Wide pumping speed range allows for direct atmospheric discharge, achieving the effect of multi-stage series operation with just a single pump.
② The single-stage design can achieve a vacuum level of 5 PA.
③ Nitrogen gas purging can be employed; cleaning and maintenance operations are simple, and repairs are convenient.
④ The screw is made of integral ductile iron, providing high strength and stable performance; the screws do not contact each other, eliminating friction, requiring no lubrication grease, preventing oil backflow, and eliminating waste gas and liquid discharge, making it clean, environmentally friendly, and energy-efficient.
⑤ The internal pump chamber and components can be surface-treated for corrosion resistance as needed, making it suitable for the special requirements of the chemical and pharmaceutical industries. 6. The screw undergoes precise dynamic balance correction, ensuring smooth operation, low noise, minimal vibration, and a long service life.
3.DRP Hydraulic Coupling Roots Pump
Features:
① The hydraulic transmission structure allows the Aifaluo Roots pump to start directly under atmospheric pressure or high differential pressure.
② The Roots pump can start and stop simultaneously with the primary pump. The Roots pump can automatically adjust its speed, preventing overload or overheating. Starting the Roots pump in advance under high differential pressure can reduce pumping time and improve the system's pumping efficiency.
③ In the event of foreign objects entering the pump chamber or sudden pressure changes, it automatically reduces speed for protection, resulting in an extremely low failure rate.
④ Simple configuration, no need for bypass pipelines, valves, or frequency converters, thus saving costs and facilitating convenient operation.
⑤ Operates smoothly and quietly, with minimal vibration, and the pump maintenance is straightforward.
