Product Overview: The GVS-500 and GVS-501 are oil-free scroll vacuum pumps designed for various industrial applications. They offer a displacement of 423 L/min at 50Hz and 505 L/min at 60Hz, with an ultimate pressure of ≤250 Pa. These pumps are characterized by low noise levels of 64 dB(A) and motor power ranging from 1.2 to 1.5 kW.

Specifications: The pumps operate on a 3-phase local voltage and feature NW25 inlet and Rc1/2 outlet connections. They are suitable for ambient temperatures between 5℃ and 40℃ and weigh 39 kg. The dimensions are 317mm in width, 585mm in depth, and 289mm in height. The backup seal materials include silicon rubber and fluoro rubber.

Key Features: These pumps maintain a high vacuum level for extended operations and require only annual maintenance under standard usage conditions. They are designed for 24-hour operation and feature air cooling, eliminating the need for oil or cooling water changes. The pumps are RoHS compliant and come with a standard water separator and optional multi-volt motor and air flush for vapor operations.

Applications: Suitable for vacuum transport, vacuum packing, vacuum forming, gas substitution, deaeration, leak testing, vacuum chuck, vacuum drying, and degassing.

Precautions and Maintenance: The pumps are intended for clean processes only and should not be used with explosive, flammable, toxic, or corrosive substances. Maintenance should be performed as per the instruction manual, and the pumps should be installed in well-ventilated areas away from explosive gases. The guarantee period is specified in the instruction manual, and maintenance intervals differ from the guarantee period.

Installation Cautions: Ensure installation in areas free from explosive and flammable gases. The pumps do not include a breaker to prevent motor burnout, so appropriate measures should be taken. An electric source cord is not included and should be used as instructed in the manual.
