Gravel Pumps
Description
GTEK G series Gravel Pumps are designed to handle very large particles for gravel and dredge operations. Capable of handling large particles at consistently high efficiencies result in low cost of ownership.The large volume internal profile of the casing reduces associated velocities further increasing component life. GTEK gravel and dredge pumps are designed to pump aggressive slurries with a wide distribution.
Applications:
Sand and Gravel
Hydraulic Mining
River Dredging
Cyclone Feed
Slag Granulation
Sugar Beet
Heavy Refuse Removal
Working Principle
Features
The unique segmented clamp ring allows casing rotation to any required angle, which removes the need for costly high wear bends.
IMPELLERS–Expulsion vanes cut down on gland pressure and reduces risk of high solid concentration in gland area.
CASING–Heavy duty casing has been designed to minimize internal velocities resulting in greater efficiency and prolonged wear life.
SEALS
EXPELLER (CENTRIFUGAL SEAL)–No gland water required
STUFFING BOX–flushed gland sealing with packing and lantern ring.
MECHANICAL SEALS
BEARING ASSEMBLY
–Grease lubricated cartridge bearing assembly,which is simple in structure,reliable in operation and easy to maintain.
–Large shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field.
- Safe and simple impeller adjustment to maintain top efficiency.
