The precision structure of the roots vacuum pump achieves long-lasting durability, worry-free mainte

The "longevity secret" of ZBK series roots vacuum pumps is hidden in its precision transmission structure. The motor drives the active rotor by a V-belt, and then the synchronous gear drives the driven rotor to rotate, leaving only a small gap of 0.4 mm between the two rotors, which not only avoids metal contact wear, but also ensures airflow tightness. The gap between the rotor and the pump body and side plates is also controlled at about 0.25 mm, and this "millimeter-level" precision design allows the equipment to maintain low friction and low power consumption in continuous operation, saving more than 20% energy compared with similar products.

Routine maintenance is also extremely easy – no need for frequent lubricant changes, just regular cleaning of the inlet filter to avoid dust clogging. Even with medium-particle media, its wear resistance extends the service life to more than 5 years. From building materials factories to sugar workshops, from pharmaceutical and chemical industries to clothing and textiles, ZBK series has become the "king of cost performance" in the field of industrial vacuum with the strength of "small volume and large energy".
