Gravel Pumps

Grit Pumps / Dredging Pumps / Sand and Gravel Pumps

GTEK Gravel Pumps

INTRODUCTION

SPECIFICATION

Description

GTEK G series 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.

Application

- Sand and Gravel
- Hydraulic Mining
- River Dredging
- Cyclone Feed
- Slag Granulation
- Sugar Beet
- Heavy Refuse Removal

Features & Benefits

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.
