Frequently Asked Questions
What is the expected lifespan of the bearings and seals?
The pump utilizes premium imported bearings with a design lifespan exceeding 100,000 hours. For sealing, it uses O-rings for static sealing and robust mechanical seals to isolate the oil chamber from the fluid, ensuring a continuous operation lifespan of 10,000+ hours.
Is the pump easy to install and maintain for operators?
Yes, it is highly user-friendly. It features an Auto-Coupling installation system that allows for tool-free lifting and maintenance. Mounting is also incredibly easy; only the wall tube needs to be embedded, while the rest of the mounting brackets are secured using standard expansion bolts.
