Hebei Zidong Pump Industry Co., Ltd
High chrome horizontal dredging gravel pump
ZIDONG ZG series pumps are designed for continuously handling the most difficult high abrasive slurries which contain too big solids to be pumped by a common pump. they are made from high abrasion-resistant 27% chrome alloy hard metal material, which are suitable for handling highly abrasive slurries in mining, explosive sludge in metal melting, dredging in dredger and river course, and other fields. GH series are high head pumps.
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 - Closed 3-vanes 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
