Pump Structure
The KNKE Fluoroplastic Pump consists of several high-quality components that ensure its reliable operation:
- Pump Body: The body features metal flanges and fluoroplastic alloy for maximum strength and corrosion resistance.
- Impeller: A high-strength impeller is attached securely to the metal shaft, ensuring optimal torque resistance.
- Mechanical Seal: The pump uses a reliable, self-adjusting, single-end mechanical seal made from durable materials to ensure long-lasting, leak-free performance.
- Frame: The stainless steel frame (1Cr18Ni9Ti) provides stability and durability.
Working Principle
The motor directly drives the impeller, which is securely connected to the motor shaft using a Morse taper. A tightening bolt secures the connection, ensuring the impeller rotates smoothly. The mechanical seal ensures the system runs without leakage, even when handling aggressive, corrosive chemicals.
