Dewatering dredge Pumps

Heavy-duty dewatering

The Prime Fluid Management team is experienced in heavy-duty dewatering, delivering cost, time and resource savings for our customers. Our Dragflow range of dredge pumps and mini dredges are a key part of solution. Dragflow are innovators in compact, portable dredge solutions, making them a natural fit for challenging and often remote, New Zealand environments. Employ dredge pumps for rapid management of solid and silt-laden water, or for ongoing heavy-duty dewatering at maximum efficiency with minimum wear and limited impact on the surrounding environment.

SITE ENVIRONMENT

Built for extreme challenges

Dragflow dredge pumps and mini dredges deal efficiently to large volumes of sediment-laden water. They are well-suited to reclamation and coastal protection work, and pond and channel cleaning.

Key features include:

High efficiency agitator: reversible and high chrome for long life and continuous flow lifting of deposited sediments.
Low rotation speed: reduced wear and long-term efficiency.
Rugged and heavy-duty construction: highly resistant components for loaded and abrasive mixes.
