Hydroman® Submersible Sand Pump Description：
Hydroman® Submersible Sand Pumps specifically designed for handling slurries with a high content of abrasive solids. The dredge pumps have been extremely successful for clients operating in specialized sectors who face severe conditions and solve very difficult applications. The electric dredge pumps are positioned as submersible dredge pumps for marine and energy sectors as well a in mining for minerals and other materials. Handling slurries with up to 70% solids content and specific gravity up to 1.7, with a capacity of up to 5,300 gpm at 275 feet of head.With high chrome wear parts and specially designed, grease packed lip seals, the dredge pumps are manufactured with exceptional structural quality to maximize the benefits of the customer’s initial investment and achieve low maintenance and service costs.

Hydroman® Submersible Sand Pump Design Features:
▪ Electric submersible motors are all Class H insulated and have a minimum 1.25 service factor.
▪ Submersible Sand Pumps are equipped with a unique lip seal system to prevent material from penetrating the seal.
▪ High quality materials ensure long life of all components.
▪ Temperature sensor, embedded in the electric motor, and Moisture sensor, in the oil chamber, are available options to protect the pump in the most demanding application.
▪ Adjustable High-Chrome suction side Wear Plate maintains maximum performance for extended periods by a simple adjustment of the gap between the wear plate and the impeller.
▪ Replaceable wear parts: casings, impellers, wear plates all can be replaced independently.
▪ Lube Oil Inspection Ports: a wide angle port outside the submersible sand pump ensures easy inspection of shaft seal oil levels as well as providing easy access for oil replacement.
▪ The excavating action is created by the High-Chrome agitator blades that lift settled sediments which then get sucked into the submersible sand pump, creating a continuous flow of concentrated slurry.
