Product Description

Overview

Zidong Pump high pressure gravel pumps are designed for long life, efficient operation and ease of maintenance.

Gravel pumps have high-chrome wet ends with expeller or stuffing box seal arrangements.

It is mainly used for long distance delivery with thicker wall in more durable working life and higher efficiency.

Design Considerations

Bearing assembly and shaft

1. The shaft is designed with a short overhang to:

- Reduce shaft deflection

- Minimise vibration

2. Provided with hardened shaft sleeve to protect the shaft

3. Bearing assembly is retained on a one piece frame

4. Grease-purged piston rings to help seal contaminates out of bearing housing

Impeller

1. Enclosed impellers to maximise efficiency

2. Pump-out vanes on both shrouds

- Minimises re-circulation

- Reduces stuffing box pressure

3. High chrome liquid ends

4. Interchangeable hard metal impellers

5. Impeller clearance is set by moving the bearing assembly

6. High efficiency impeller optional

Single casing with assembly clamps

1. Easy assembly and disassembly of liquid end

2. Clamp design facilitates rotation of volute

3. Large volute reduces friction and wear

4. Minimal parts + simple design

Centrifugal seal option

1. Reduces or eliminates need for gland service water

2. Reduces sleeve wear and possible bearing contamination

Applications

They are suitable for delivering slurries in Mining, Explosive-sludge in metal melting,

dredging in dredger and course of rivers, and other fields.
