The oil-free diaphragm vacuum pump is a dry-running vacuum device. It generates vacuum through the reciprocating motion of the diaphragm, eliminating the need for pump oil. This pump features pollution-free operation, corrosion resistance, low maintenance requirements, and a long service life. It is widely applicable in laboratories, medical, electronics, chemical, and environmental protection fields, serving as a replacement for traditional oil-sealed pumps to meet the vacuum demands of high cleanliness and high stability scenarios.
