FRPP polypropylene acid alkali resistant vertical inline pipeline centrifugal chemical transfer pump

Vertical inline centrifugal pump engineered for corrosion-resistant pipeline transfer of aggressive liquids. The FPL series uses reinforced polypropylene (FRPP) construction with an integrally molded impeller and shaft for improved mechanical strength and long service life. Its compact vertical inline layout reduces footprint and simplifies installation directly into existing pipeline runs.

Key features

• Construction: Reinforced polypropylene (FRPP) pump body, impeller and shaft molded as an integrated assembly for high corrosion resistance and mechanical strength.
• Seal: WB2 mechanical seal with silicon carbide (SiC) faces and PTFE secondary components for reliable sealing against chemical attack.
• Operating temperature: Designed for pumped-fluid temperatures from -10°C to 80°C.
• Design: Vertical, inline, centrifugal configuration optimized for continuous chemical transfer in pipeline systems.

Typical applications

• Transfer and circulation of corrosive liquids, including acid and alkali solutions
• Chemical processing, plating and surface treatment lines
• Industrial effluent handling and recirculation
• Any application requiring a compact, corrosion-resistant inline pump for chemical liquids

Buyer notes

• Verify compatibility of FRPP with your specific chemical media and temperature conditions prior to ordering.
• Confirm required hydraulic performance (flow, head), flange/connection sizes and motor compatibility — model example: 50FPL-28 (MPN: FPL).

Benefits

• Excellent chemical resistance from FRPP construction
• Reduced maintenance and long service life due to integrated impeller/shaft molding
• Compact vertical inline footprint simplifies system layout and saves floor space
• Mechanical seal with SiC/PTFE materials for robust, corrosion-resistant sealing
