Bonve SS316L Rotary Lobe Pump for High-Viscosity Vaseline Handling
In cosmetic/pharmaceutical production requiring gentle processing of semi-solid hydrocarbons, thermal stability, shear sensitivity, and hygiene compliance are critical priorities.
Bonve's 316L Stainless Steel Rotary Lobe Pump is engineered for handling Vaseline (15,000-80,000 cP at 25°C) while preserving its colloidal structure and additive uniformity.
Enhanced Structural Advantages：
1.Corrosion-resistant Bi-wing rotor system with hardened 316L stainless steel (Ra <0.8μm)
2.Adjustable clearance control (0.1-0.3mm) for thixotropic semi-solids
3.Patented mechanical seal system
Vaseline-Specific Challenges
Traditional pumps struggle with:
1.Shear-induced colloidal structure breakdown (critical for occlusive properties)
2.Phase separation in additive-enhanced formulations (≤8% microcrystalline wax/actives)
3.Thermal degradation during transfer (melting point: 38-60°C)
4.Hygiene risks from residual material in flow paths
Bonve's Optimized Solutions
1.Low-Shear Processing
2.Bi-wing rotors at 0-25 RPM ultra-low speed maintain crystalline network integrity
3.Progressive suction geometry prevents air inclusion during phase transition
4.Temperature-Controlled Transfer
Hygienic Design：
1.FDA-compliant surface finish (Ra <0.8μm post-polish)
2.360° no seam inside the pump front
3.Support CIP/SIP
Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.

Main Parts of the Complete Pump
Bonve complete pumps are usually composed of bare shaft pump, coupling and its guard, geared motor and base plate. With your order, bare shaft pump or complete pump is supplied.
Bare Shaft Pump Structure
Structure Details
Bonve has an advantage over lobe pump that no other company can match.
1.Rotor:The error of the rotors processed by CNC is extremely small. The unique rotor perfectly seals the inlet and outlet of the pump. The vacuum degree of the pump is up to -0.095MPA. The rotor material and type can be selected according to the characteristics of the pumped product.
2.Shaft: The transmission shaft is processed by CNC machining center, which has characteristics of high precision, high bending strength and strong wear resistance.
3.Pump cavity: The pump cavity is sealed by a pump cover that can be opened quickly, enabling quick maintenance of the pump. The pump body is processed by CNC machining.
4.Gears:High-precision, High-Standard synchronous gears have good meshing, smooth transmission, low noise, and excellent bearing capacity.
5.Mechanical seal: The seal material and type are selected according to the characteristic of the pumped product, to ensure zero leakage, no pollution, and more environmental production.
6.Bearings: Six bearings arranged in a separate arrangement increase the concentricity of the pump operation, enhance the bearing capacity of the shaft and make the pump running more stable, thereby increasing the service life of the shaft and the mechanical seal.
7.Gear box: The gear box is processed by CNC, with high precision, high concentricity and strong versatility.
8.Spindle:We use splines the bearings and spindle, makes the pump less likely to slip. The high-precision spline makes the pump run more smoothly, and the service life is much higher than that of its peers.
