ZGH series high-pressure sand dredging pumps are engineered for demanding applications requiring long-distance slurry transport with thick-walled construction. These heavy-duty pumps deliver exceptional durability and efficiency when handling highly abrasive materials containing large solids that exceed the capabilities of standard slurry pumps.

Designed for continuous operation in challenging conditions, ZGH pumps feature robust construction, simplified maintenance procedures, and optimized performance characteristics for extended service life.

• Short overhang shaft design minimizes deflection and reduces vibration
• Grease-purged piston rings prevent contaminants from entering bearing housing
• Enclosed impellers maximize operational efficiency
• Pump-out vanes on both shrouds minimize recirculation and reduce stuffing box pressure
• High-chrome liquid ends with interchangeable hard metal impellers
• Simplified assembly and disassembly of liquid end components
• Minimal parts count with straightforward design for reliability

Pump casing and impeller constructed from 27% high-chrome alloy with extra-thick walls for superior wear resistance and minimal maintenance requirements.
