The KB series acid resistant self-priming pump is a robust industrial solution specifically designed for the safe and efficient transfer of corrosive chemical liquids. Featuring an innovative internal Teflon Bellow Seal self-cooling design, this wastewater treatment pump eliminates leakage risks and ensures long-term reliable operation in harsh chemical environments. The seal operates without external cooling, reducing maintenance requirements and extending service life.
With a powerful self-priming capability of up to 6 meters and a built-in check valve to prevent liquid backflow, this chemical self-priming pump eliminates the need for manual priming before each startup, significantly improving operational efficiency. The optimized self-priming chamber design ensures fast priming times, even after extended shutdown periods. Available in multiple corrosion-resistant materials including CFRPP, FRPP, CPVC, and PVDF, it is ideal for handling a wide range of acids, alkalis, and chemical solutions.
Constructed from high-performance engineering plastics, this corrosion resistant self-priming pump offers excellent resistance to most inorganic acids, alkalis, and organic solvents. The material options allow you to select the most suitable construction based on your specific fluid properties and operating temperatures, ensuring maximum pump life and reliability.
The optimized self-priming structure delivers a maximum suction lift of up to 6 meters under standard conditions. The integrated check valve prevents liquid from draining back into the tank when the pump is stopped, ensuring instant priming on subsequent startups. This eliminates the need for foot valves in many applications, reducing maintenance costs.
The unique Teflon Bellow Seal self-cooling design effectively prevents chemical liquid leakage, protecting the environment and ensuring worker safety. This seal design also eliminates the risk of shaft wear and extends the service life of the pump by reducing friction and heat generation.
The modular design allows for quick and easy disassembly and maintenance without the need for special tools. All wearing parts are readily available and can be replaced on-site, minimizing downtime and maintenance costs for industrial facilities. The pump’s simple design also reduces the risk of operational errors.

We offer custom pump body materials (CFRPP, FRPP, CPVC, PVDF) to match different chemical properties. We also provide various rubber seal materials (NBR, EPDM, VITON) and spring material options (HASTELLOY-C, SUS316) for optimal chemical compatibility in harsh environments.
We offer low-head and high-head versions to meet specific performance needs, as well as explosion-proof motors for use in hazardous locations. Our team can also customize inlet and outlet connection specifications (JIS, DIN, ANSI) and provide integrated control systems for automated operation.
Every KB series acid resistant self-priming pump is manufactured in accordance with strict international quality standards and undergoes comprehensive performance testing before leaving the factory. Each pump is tested for priming capability, flow rate, head, and leak tightness to ensure it meets our rigorous quality requirements.
We offer a 12-month warranty against any manufacturing defects. Our dedicated technical support team provides expert assistance with pump selection, system design, and troubleshooting. We also offer on-site installation and maintenance services, and our extensive spare parts network ensures fast delivery to minimize production downtime.
The KB series pump can handle liquids with specific gravities up to 2.0, depending on the model and motor power. We offer different motor configurations to accommodate higher specific gravity liquids, ensuring reliable performance.
The KB series pump has a built-in check valve that prevents liquid backflow, so a foot valve is not required in most applications. However, we recommend installing a strainer at the inlet to prevent debris from entering the pump and damaging the impeller.
