Biref introduction:
Fluoroplastic (PFA-Lined) Axial Flow Pump
This fluoroplastic axial flow pump features PFA-lined flow components, providing exceptional corrosion resistance for handling highly corrosive media, including strong acids, alkalis, and aggressive chemicals. Designed for high-flow, low-head applications, it is ideal for demanding industrial processes.
Key Advantages of PFA Lining:
Superior Corrosion Resistance - Withstands nearly all strong acids, alkalis, oxidizers, reducing agents, and organic solvents.
Widely Trusted Material - PFA is the most commonly used lining for extreme chemical resistance.
Robust Performance - Handles high temperature & pressure, low temperature & vacuum, and sudden thermal shocks in harsh conditions.
Reliable Durability - Maintains integrity even when exposed to highly corrosive fluids.

Structure:
- Elbow structure for pump body,piece-welded body and casted body for selection.
- Pump impeller is cantilever type with spherical hub,impeller blades are adjustable.
- Pump shaft adopts butt welding workmanship,the wetted parts or possible wetted parts are made from stainless steel or other corrosive materials.
- Mechanical seal and packing seal can be interchangeable.
- Adopting cartridge mechanical seal,reliable and easy for maintenance.
- Enlarged cylinder type bearing housing with oil level glass and oil filler,which extends the bearing life and interval of lubricant changing.
- Pump and be driven by motor through V-belts,gear box or directly through couplings. For pipe hung pump,the universal joint transmission must be adopted if the motor ≥200kW.

The instruction of installation methods:
K suspended installation
The pump and motor are totally articulated, the pump and motor are no need basis, and there are no expansion joint and transport by the triangle belt. The caliber is 300~500mm, only the motor affiance is under 55kw have this installation type.
E half suspended installation
There are no basis at the installation scene, and the pipe bear the weight of pump body. You'd better design a floatable bearing for the pump that caliber≥700 at the horizontal direction and the connection pipe. We only recommend triangular belt transmission and gamble transmission, no expansion joint in the pipe connected with the pump.
F horizontal installation
The base plate is needed when install pump and motor. If the working condition is high temperature, the pipe connected with the pump body need the expansion joint, the pump and motor could translated by the triangular belt of directly transmission.
