5X Z512-604-3000N DC12V Mini Negative Pressure Vacuum Pump 5L/Min 65-120Kpa Air Pump with Bracket

2. In this way, the fixed volume of air in the pump chamber is compressed (the compressed suction port is closed, and the exhaust port forms a slightly open positive pressure), stretched (the compressed exhaust port is closed, and the negative pressure suction port is opened). The pressure difference, at which the gas pressure (suction) enters the pump chamber and is discharged through the exhaust port. 1. The micro-pump is by a micro-DC motor, which drives the internal mechanical eccentric eccentric motion, and the eccentric motion drives the internal reciprocating motion of the diaphragm. 4. Small size, stable and reliable, hand- pump suction instrument, low noise, low power consumption. Especially suitable for high negative environmental requirements. 3. Micro-type vacuum pumps are mainly used in electrical , industrial , vacuum -keeping machines, automobile exhaust gas reforming equipment, gas analysis and sampling, instrumentation and other fields. Completely maintenance-free, no oil pump, no pollution to the transmission medium, and can work continuously for a long time.
