The Grindex Minex-3 Compact Professional Submersible Drainage Pump is a powerful and durable pump engineered for construction dewatering, industrial drainage, mining sites and demanding professional applications. Designed with Swedish engineering and built for reliability, the Minex-3 offers higher performance while maintaining the portability and compact footprint required for on-site use.
The pump features a semi-open impeller design, allowing it to efficiently handle dirty water containing sand, grit and small solids commonly encountered on construction and industrial sites. A double mechanical seal system operating in an oil chamber protects the motor from water ingress and significantly improves pump lifespan and reliability in continuous duty applications.
Constructed with a robust aluminium pump body and stainless steel shaft, the Minex-3 is built to withstand harsh environments and heavy-duty operation. Integrated thermal motor protection safeguards the motor from overheating, while the compact design and ergonomic handle make the pump easy to transport and install for rapid deployment in dewatering situations.
The Minex-3 is ideal for professional contractors requiring a compact but high-capacity drainage pump capable of reliable operation in tough conditions.
