GD :
■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: double mechanical seals (silicon
carbide), epoxy resin cable, watertight body structure that meets
IP68 requirements, an auto-cut motor protector, and a watercooling 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 :
■A water cooling motor with rubber suction pads for residual
removal as low as 1 mm (0.39").
■The best pump for removing water from flat surfaces because
of its portability and light weight.
■Equipped with double seals (silicon carbide), epoxy resin cable,
IP68, an auto-cut motor protector and rubberized hydraulic
components that can withstand any tough applications.
■Standard discharge:Outlet Discharge 1" LOT 1-74(Optional 2" LOT 2-74)
GD :
■Civil engineering, dewatering of tunneling and ground works, and for
use in storm water sewers.
■Dewatering of fluids containing solids.
■Ease of mobility for use by contractors, installers and service
industries.
GDR :
■Basement / Pool / Pond water removal.
■Residential, Commercial residue dewatering.
