Why The Guardian® Pump Range Is Better

Toughened - Metal Is Best

Internal components in the wetend are tough metal, not elastomer. Harsh operating environments quickly destroy elastomer components, while toughened steel components power on. Guardian is dry run tolerant and can run on the snore.

Productive - Less Downtime More Production

Guardian has been designed for tough environments, to keep on pumping when traditional dewatering pumps might fail.
Less mining downtime, more production.
