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.
Large flow capacities achieved with almost no vibration, or noise, by use of the axial and mix flow design.
HIGH-QUALITY BRONZE : Widely acclaimed for its ability to withstand corrosion, even to the erosion of sea water and brine and is proved to be able to substantially extend time to service,used on the Upper Cover, Bearing Bracket, & M. Seal Bracket of our pumps. (L-200/250/300A only)
POWER-SAVING & HIGH-EFFICIENCY ALBC3 (Aluminum Bronze) IMPELLER : Utilizes wear-resistant and anti-corrosion ALBC3 (Aluminum Bronze) Impeller, the same material as the propellers of boats and vessels.
Robust construction and compact design with a dry motor, double mechanical seals and impeller flow guide vane for high efficiency.
Pump manufactured with heavy duty housing, cable leads are isolated by hardened epoxy for water proofing, and double mechanical seals.
High solids, epoxy coating prolongs metals from corrosion and oxidization.
L Series are equipped with Sacrificial Anode. Sacrificial Anode are create from a metal alloy with a more negative electrochemical potential. Sacrificial Anode are highly active metals, that are used to prevent pump material surface from corroding.
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.
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.
