Products Details

Chemical transfer is vital in textile production, impacting quality, efficiency, and costs. BONVE’s stainless steel tri-lobe rotary lobe pump is the solution.

Textile chemicals like dyes and auxiliaries are often corrosive. Ordinary pumps wear out quickly, causing leaks, waste, and quality issues. BONVE’s pump, made with high-quality stainless steel, resists corrosion, lasts longer, and cuts maintenance costs.
Its tri-lobe rotor design ensures steady flow with minimal pulsation. This means even distribution of chemicals on fabrics, boosting dyeing quality. It also reduces wear on pipes and equipment, improving overall efficiency.
Whether moving chemicals from storage to reactors or through production lines, this pump fits perfectly. It controls flow precisely to meet process needs, speeds up production, and helps textile businesses stay competitive.


A leading Bangladeshi textile firm once struggled with chemical transfer—corrosive dyes and auxiliaries wore out ordinary pumps, causing leaks, uneven dyeing, and costly downtime.
Enter BONVE’s stainless steel tri-lobe rotary pumps. Their corrosion-resistant build and steady flow (from the tri-lobe design) solved it all: less waste, consistent fabric quality, and fewer breakdowns. Now, production is 30% more efficient, maintenance costs cut by half.


About Bonve rotary lobe pump


Premium Stainless Steel Build

Made with 316/316L stainless steel, they resist corrosion from harsh fluids (e.g., textile dyes, 64% acetic acid), ensuring durability and lowering replacement costs.
Optimized Rotor Design
Two-lobe and tri-lobe options deliver steady flow—tri-lobe minimizes pulsation. Enables efficient intake, gentle discharge, and low shear to protect delicate media (jams, resins).
Reliable Sealing
High-quality mechanical seals (standard or specialized) prevent leaks. Handles up to 80°C and acidic conditions, avoiding waste and maintaining pressure.
Broad Versatility

Works with viscosities up to 1.5 million cps and 60% solids. Ideal for food, chemicals, mining, wastewater—adapts to diverse transfer needs.


Working Principle


 

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.
