Technical Information

A rotary pump utilizes synchronously counter-rotating rotors to create a vacuum at the inlet for fluid suction,sealing it in isolated chambers and smoothly pushing it to the outlet for continuous,pulsation-free delivery.Its core advantages include flow rate unaffected by back pressure,adaptability to high-viscosity media,and sanitary design to prevent contamination,making it suitable for industries like food and pharmaceuticals.Usage requires avoiding dry running,particulate matter,and corrosive liquids,with regular inspection of seal conditions.

A rotary pump utilizes synchronously counter-rotating rotors to create a vacuum at the inlet for fluid suction, sealing it in isolated chambers and pushing it to the outlet for continuous, pulsation-free delivery. Its advantages include flow rate unaffected by back pressure, adaptability to high-viscosity media, strong self-priming capability, and sanitary design, making it widely applicable in industries like food and pharmaceuticals. Selection requires evaluating parameters such as flow rate and viscosity.

Bonve's comprehensive pre-shipment inspection protocol for rotary lobe pumps, including performance tests (flow/pressure/etc.), visual inspection, 60-minute hydrostatic testing, 120-minute continuous operation validation, and quality certification systems – guaranteeing every unit meets stringent reliability standards.

details critical steps in rotary pump assembly—including cleaning,bearing positioning,rotor meshing accuracy,pump body alignment,sealing system calibration,and accessory installation—highlighting how precision assembly ensures efficient and durable pump operation.

During the design preparation phase of Bonve rotor pumps, operating conditions are translated into actionable parameters: increasing tooth volume ratio for high-viscosity media, optimizing the phase angle of two-lobe rotors for low-pulse scenarios, and applying special coatings for corrosive environments. Rotor profile design balances volumetric efficiency, contact stress, and noise control through parametric modeling—single-lobe designs for high pressure resistance and three-lobe designs for quiet operation.

Bonve's rotor pump excellence stems from micro-precision machining: Cryogenic grinding replicates rotor profiles with optical-indexed synchronization, pump bodies achieve ∞-cavity accuracy via single-setup turning-boring, and shafts gain reliability through cold-formed key ways and roller burnishing. Component clearance matching and Bonve's three-pillar system (precision evolution, error-proofing, light-gap verification) transform designs into high-efficiency, low-pulsation, long-life industrial solutions.
