FZB fluoroplastic self-priming chemical pump

Fluoroplastic-lined, self-priming chemical pump designed for handling highly corrosive acids and alkalis in industrial processes. All wetted flow parts are made of fluorine-based plastics to deliver long service life, excellent chemical resistance and high-temperature performance while the pump’s structural components are reinforced for pressure durability.

Key features

• Construction: metal pump body lined with fluoroplastic; pump cover and impeller are metal inserts coated by fluorinated plastic using sintering and pressing for a bonded, wear-resistant surface.
• Sealing: external bellows mechanical seal. Static ring manufactured from 99.9% alumina ceramic (or silicon nitride); dynamic ring made from PTFE-filled material for superior chemical and wear resistance.
• Pressure reinforcement: pump inlet and outlet are fitted with cast-steel reinforcement to improve pressure resistance and mechanical strength.
• Self-priming capability: can lift liquid from below the pump installation position; typical suction height 2–4 m (site-dependent).
• Durability: fluoroplastic flow parts provide acid/alkali corrosion resistance, high temperature capability, no aging, and reduced wear for extended operational life.

Typical applications

• Transferring corrosive liquids from underground or bottomless tanks
• Circulation between multiple acid/alkali storage tanks
• Acid/alkali discharge and handling in chemical processes
• General chemical processing, plating, pickling, and industrial wastewater lines where corrosion resistance is required

Available model information

• Series/MPN: FZB / FZB-L

Notes for buyers

• Confirm compatibility of fluoroplastic materials with your specific fluid and operating temperature.
• Specify required connection sizes, flow rate and head when requesting quotes or technical drawings to ensure correct model selection.
