12V Vacuum Pump with Bracket 5Lmin 65Kpa DC Motor Driven Negative Pressure Micro Pump for

Feature: 1. DC Motor Drive: The negative pressure vacuum pump is driven by miniature DC motor, which drives the internal mechanical eccentric motion. The eccentric motion drives the internal reciprocating motion of the diaphragm. 2. Working Principle: Compress the air with a fixed volume in the pump chamber (compression suction port close, slight open positive pressure at the exhaust port), stretch (compression exhaust port close, negative pressure suction port open). Under a pressure difference, the air pressure (suction) enters the pump chamber and is discharged from the exhaust port. 3. High Performance: This micro vacuum pump has a suction of 5Lmin, a vacuum degree of 65kPa, a maximum pressure of 120kPa, low noise, low power consumption, and is particularly suitable for high negative environmental needs. 4. Convenient and Practical: The oilless vacuum pump does not pollute the transmission medium, requires no maintenance, can work continuously for a long time, which is stable and reliable. Equipped with bracket for easy fixation. 5. Wide Application: This micro vacuum pump is suitable for electrical products, industrial products, vacuum preservation machine, exhaust gas conversion and emission device, gas analysis and sampling, instruments and other fields.
