For pumping from a chemical tank. For mixing, agitation and emergency situations


1. The world's first fully corrosion-resistant, non-metallic magnetic drive submersible pump for acids and alkalis


Our submersible pump is made of carbon fiber reinforced polypropylene (CFR PP) for the main pump body, and high-purity ceramic or Rulon® for critical parts. No metal is used in wetted parts. Due to the corrosion resistant materials, our submersible pump is perfect for acidic and alkaline solutions.

2. A built-in thermal protector for automatic motor shutdown
When temperatures reach abnormal levels due to electrical or mechanical factors during operation, the built-in thermal protector automatically shuts off the pump. Any abnormal load, single-phase operation or liquid temperatures exceeding the maximum limit are detected to prevent failures.

3. Lightweight construction and easy handling in emergency situations
For example, the YD-502/512GW weighs 57.3 lbs. (26 kg). With convenient grip handles, these pumps can be transported quickly in the event of an emergency. It can be used at any location where an electric power supply is available.
