Integrated Screw Vacuum Pump

The ISV series energy-saving screw vacuum pump utilizes a next-generation screw profile. The precision of the screw rotor tooth profile exceeds industry standards and operates under light load. The exceptional single-piece screw main unit structure works with direct motor drive, eliminating transmission loss and ensuring 100% efficiency.

Vector frequency converter control offers fast response time, balanced current distribution, and superior torque enhancement effects.

Permanent Magnet Frequency Converter Technology

The ISV oil-injected screw vacuum pump employs a special permanent magnet variable frequency motor. This significantly improves drive motor efficiency and saves energy.

Using high magnetic resistance, high-temperature-resistant permanent magnets, there is no magnetization loss even at 150°C. The ultra-high torque design,

stepless speed variation, wide frequency adjustment range, easy frequency control, and dynamic response performance enable rapid response to large-scale adjustments while precisely regulating vacuum levels.

Frequency-adjusted startup provides soft start and reduces grid load.

With super energy efficiency, motor efficiency reaches 98% or higher, complying with IEC 60034-30-1:2014 "Variable Speed AC Motors" standard IES level.

Power factor exceeds 98%, alleviating customer grid load.

Ultimate Vacuum

• Environment:

• Water ring vacuum pump:

  • 25 kPa

  • Each vacuum pump requires an independent water pipe and an independent electrical control box.
  • A circulation pump and cooling tower must be installed to provide continuous cooling water.

Efficiency

1. Overall efficiency is approximately ¥630.

2. The water ring vacuum pump is calibrated based on maximum suction speed at 15°C water temperature and 100% relative humidity.

Screw Vacuum Pump

• Offers high integration and intelligent features. The machine's front can be directly connected to the vacuum line, requiring no base or additional equipment. Special working conditions may require pre-filter
  • Overall efficiency is approximately ¥85.
  • Energy saving rate can reach ¥25-¥40.

Smart Vacuum Solution

The ISV screw vacuum pump can maintain a set pressure point during operation and adjust its speed to maintain this pressure. In this case, using WS technology can save over 30% energy compared to traditional technology.

ISV screw vacuum pumps are configured for maximum operating performance only when necessary. During rapid evacuation of the vacuum lock chamber or dry running conditions, when maximum performance is not required, the vacuum pump can reduce energy consumption by over 30% compared to standard operation mode.

In almost every production environment, the vacuum system does not need to provide peak performance throughout the entire production process. During the process cycle, pumping cycle, or when the machine is idle, the smart WS screw vacuum pump delivers peak performance only when required by the process, thus ensuring maximum reduction in energy consumption and maintenance costs.
