Grindex Dewatering Pump: Minex

Electrical submersible 1~ & 3~ drainage pump

The Minex pump is the smallest model in the drainage range, but it shares all important features and benefits with the larger models, resulting in the lowest cost per cubic metre pumped.

The drainage range of pumps drain water, not your wallet!

The revolutionary hydraulic design ensures high wear resistance and dramatically reduces performance drop due to long time wear.

Available in both 50hz and 60hz models.
