Today we paid a return visit to a large group company in Shandong, one of China’s earliest enterprises achieving large-scale resin production. The group now owns 6 subsidiaries, covering the R&D, production and sales of resin, polyester polyol, PU resin for artificial leather, PU resin for shoe soles, PU adhesive, water-based PU resin, solvent-free PU resin, thermoplastic TPU and other related products, with annual sales exceeding over 3 billion RMB.
To meet growing production capacity, the company expanded its polyester polyol production line in 2024 and needed a batch of transfer pumps for tank truck unloading and tank storage to production line transfer. After extensive field investigation and brand comparison, they finally selected Bonve lobe pumps and adopted our customized transfer solution.

Why Choose Bonve Lobe Pump for Polyester Polyol
- Customized reliable mechanical seal
Specially self-developed mechanical seal structure for polyester polyol medium, effectively avoiding leakage and achieving long service life.
- Precision gearbox and bearing design
The main and auxiliary shaft adopts three-bearing three-point supporting structure with precise collinear positioning. It effectively restrains shaft radial runout and axial movement, improves shaft rigidity and concentricity, keeps stable operation under high pressure, reduces wear of mechanical seal and extends service life.
- High-precision flat key transmission instead of expansion sleeve
Canceled the traditional synchronous gear expansion sleeve fixing structure, adopted flat key connection. All key parts are processed by Taiwan CNC high-precision machining, ensuring easy installation and eliminating shaft slipping under high pressure.
- Professional industry experience & full after-sales support
With 20 years of rich experience in high-viscosity fluid transfer, our professional technical and after-sales team provides strong technical support and worry-free operation & maintenance service.
If you are looking for a proven pump solution for Polyester polyol, Bonve's lobe pump is an ideal choice.
