Zhejiang YonJou Technology Co., Ltd sell "CQB Magnetic Drive Pump"

Built to the HG/T 2730 standard, the CQB magnetic drive pump encloses its impeller and driven magnetic coupling within a watertight canister inside the pump body, eliminating the need for a shaft seal and removing any leakage risk other than through damage to the pump housing. Available in engineered plastic, rigid ceramic or stainless steel, it suits most corrosive liquids with minimal risk of product contamination. The coupling uses circularly arranged neodymium (NdFeB) super-strong magnets encased in stainless steel, preventing slippage even with high-specific-gravity liquids. As YONJOU's standard pump for these applications, the CQB can also be customized with a heating jacket on the volute for liquids that cannot be pumped cold.
