Having a problem getting a pump that is the answer to an underwater vacuum cleaner ... check these out! Bigger than your average aquarium pump, these appear to do the job!

N.U.S. has just taken delivery of the new Godwin Heidra hydraulic submersible line of pumps.

They are landed in Canada and available for rental or purchase. The Heidra is an ideal pump for diving contractors,since it can pump solids and liquids independent of depth and suction limitations experienced by most pumps. The Heidra hydraulic power packs supply up to 4,000 GPM and are ideal for other underwater hydraulic tool applications. The pump line ranges from a 3 inch pump with a flow of 420 gallons per minute to a 12 inch pump with a flow of 5,000 gallons per minute.
