The Chemical Submersible Pump is engineered specifically for underground storage tanks, delivering efficient positive-pressure liquid transfer from storage vessels to filling dispensers or dispensing equipment.

Designed for high reliability and clean fluid transfer, the pump features a rotor encapsulated in 304 stainless steel paired with specially engineered graphite bearings. This construction ensures that all wetted parts (components in direct contact with the liquid) remain non-contaminating and highly resistant to chemical corrosion, significantly broadening its operational envelope across various industrial applications.

Chemical Submersible Pump Key Features & Operational Advantages

• National Explosion-Proof Certification: Certified for safe deployment in hazardous and explosive environments.

• Cavitation-Free Performance: Eliminates cavitation phenomena to ensure stable output and protect system integrity.

• Positive Pressure Delivery: Pushes liquid efficiently through long-distance pipelines and allows a single pump to supply multiple dispensing units simultaneously.

• Integrated Pressure Relief: Contains a built-in relief valve to safely manage and maintain stable pipeline operating pressure.

• Comprehensive Thermal Protection:

  • Features a temperature control protector embedded directly within the motor stator.

  • Triggers automatic shutdown if the internal motor temperature reaches 95°C.

  • Features automatic shutdown under abnormal electrical conditions when motor current exceeds normal operating limits.

• Full 304 Stainless Steel Construction: Provides structural durability with complete rust and corrosion resistance.
