Hard metal horizontal single-stage sand suction pump

ZIDONG PUMP ZG Series pumps are designed to handle very large particles for gravel and dredging operations.

The ZIDONG PUMP range of dredge and gravel pumps is designed specifically for continuous pumping of extremely aggressive slurries, with a wide particle size distribution. Capable of handling large particles at consistently high efficiencies results in low cost of ownership. The large volume internal profile of the casing reduces associated velocities further increasing component life.

ZG Series Profile

Discharge Diameters 4” to 14” (100mm to 350mm)

Heads Through 70 m

Flow rates Through 2,700 m3/h

Casing Pressure Tolerance 2,020 kPa

ZG Series Features

Wet-End Design

The unique segmented clamp ring on larger size units and solid on smaller pumps, facilitates casing rotation to any angle, reducing the need for costly high wearing bends. Minimal maintenance is required.

1. Impeller – front and back shroud expulsion vanes reduce gland pressure and intrusion of high concentrations of solids in the gland area. Efficiency is maintained by minimizing suction side recirculation. Specially designed and shaped impeller vanes allow the handling of extraordinarily large particles. The unique casing design and sealing vanes prevent abrasive solids intrusion at the sealing faces.

2. Casing – The large, robust casing has been designed to reduce internal velocities resulting in minimum efficiency loss and improved casing wear life. The casing is made up of three components to reduce maintenance time and costs associated with a one piece design.

Seals

1. Expeller (Centrifugal Seal) – no external sealing water required where applicable

2. Stuffing Box – flushed gland sealing with braided packing and a lantern ring

3. Mechanical Seals

Bearing Assembly

1. Cartridge-style bearing housing allows for removal from pump and assembly in controlled environment

2. Oversized shaft diameters and reduced overhang in the wet-end contribute to long life and reliability in the field
