Product Information
- Name : ZXPB Explosion-Proof Self-Priming Centrifugal Pump, Stainless Steel for Flammable Corrosive Chemical Transfer
- SKU : BLT-196
- Category : centrifugal-pumps
ZXPB explosion‑proof self‑priming centrifugal pump is a stainless‑steel unit built for hazardous‑area jobs, it handles flammable and corrosive media with no foot valve and only one‑time priming for steady pumping performance.Compact‑built, this pump runs stably with simple operation and low‑effort maintenance. It offers high efficiency and long service life. Outfitted with corrosion‑resistant mechanical seals and stainless‑steel wetted components, it moves acids, alkalis and chemical media for chemical and pharmaceutical plants. Copper impellers and explosion‑proof motors are available for gasoline and other high‑risk flammable liquids to satisfy hazardous‑location safety codes.

Working Principle
Fill the pump casing with priming liquid before startup. Driven by the motor, the high‑speed spinning impeller creates negative pressure inside the pump. Air drawn from suction lines mixes with liquid, then flows into the gas‑liquid separation zone. Air is vented away while liquid recirculates inside the pump. Air in suction piping is gradually evacuated to finish self‑priming, allowing continuous fluid delivery. Liquid stays trapped inside the pump after shutdown, so no re‑priming is required for restarts.
Application Fields
Chemical Processing: Transfer acids, alkalis and salt solutions for process circulation
Petroleum & Solvent Handling: Pump gasoline and other flammable hazardous liquids
Pharmaceutical Manufacturing: Move corrosive process fluids within explosion‑rated facilities
Hazardous Plant Operations: Replace standard centrifugal pumps, remove foot‑valve installation work
Tank Transfer & Industrial Sites: Material transfer for factories and tank unloading under explosion‑proof requirements
