GD/GDR Series – Submersible Portable Dewatering / Residue Water Pumps
GD/GDR Series – Submersible Portable Dewatering / Residue Water Pumps
Description :
GD Series
The GD models are designed for the construction industry because they are lightweight, portable, and
durable. The motor frame and mechanical seal bracket are made of aluminum alloy – that provides extra water cooling, to the motor, when water flows through. Features an all new design with exchangeable discharges, that are available in vertical and horizontal orientation. They also provide extra adaptability and flexibility to various conditions of installations, such as: confined spaces, 8 inch narrow wells or shallow water.
The model is equipped with: mechanical seals (silicon carbide), epoxy resin cable, watertight body structure that meets IP68 requirements, an auto-cut motor protector, and a water-cooling motor.
The impeller and the hydraulic components are made of a special rubber that is durable and capable of handling construction site dewatering.
The models are available in the manual version and the automatic version – equipped with a built in floating switch to automatically switch the pump on and off.
The impeller is made with an urethane rubber that provides extra wear-resistance on construction site dewatering.
GDR Series
A water cooling motor with rubber suction pads for residual removal as low as 1 mm (0.39″). Start up at water level of 5 mm.
The best pump for removing water from flat surfaces because of its portability and light weight.
IP68, an auto-cut motor protector and rubberized hydraulic components that can withstand any tough applications.
Design for civil engineering, light weight for easy portability, double outer casing water cooling motor make it possible to run the pump to low water level.
Best waterproof structure, automatic rest motor protector and double mechanical seal made of silicon carbide. Durable and leakproof.
Compact, strong design and easy operation in any place.
Impeller made of high chrome alloy (HiCr) steel with a hardness of 55~60 HRC. Harden and abrasion resistant.
Equipped with a cast iron (FCD) agitator to create powerful stirring and pumping action for slurry.
A precision manufactured motor is achieved by utilizing the highest standard of quality control. All rotors
adopt heat treatment methods for drive shaft assembling, and stator winding impregnated with varnish that
is heat dried in an industrial oven. The Water Resistance for Pump can reach IP68 Grade.
HCP's professional assembly line, complimented with a synthesized production test, ensures the highest
level of pump quality.
Standard accessories include : cable with an epoxy resin sealed water-resistant cable base, Auto-cut
Protector, dual mechanical seals and lip seal design.
Best structure design, has a dry motor, IP68, double mechanical seals, equipped with an auto-cut protector, pump casting, outer cover is stainless steel, and acid-resistant silicon carbide seals.
The Stainless series is suitable for all light acid, corrosive and/or sea water application fluid in pH value between 4~10pH. For Strong Acidity and Alkalinity applications, please use the specified chemical pump.
Investment Casting
Precision casting with the use of an advanced stainless investment casting method, that produces the highest quality with a smooth surface finish.
Viton O-ring
Viton O-rings are used throughout the pump to give better pump life in corrosive acid and aggressive media.
Austenitic Stainless Steel(SUS300 series)is used in SF/SA series. SUS316/SCS14 is better than SUS304/SCS13 in water application of light acid-base.
