Overview

The heavy duty ZH(R) series pumps are designed for conveying strongly abrasive slurries. This range of pumps are mainly used in mining, electric power, metallurgy, coal, environmental protection and other industries to convey slurries containing strong abrasive solid particles.

Specifications

Discharge size range: 25mm to 450mm [1’’ to 18’’]

Flow rates to: 5000m³/hr [22,000GPM]

Heads to: 73m [240ft]

Key Features

Double pump casing construction with interchangeable rubber and metal lined design[Figure3] provides ease of maintenance and minimal downtime.

Bolt-connection design pump casing achieves easy disassembly and maintenance with lower cost.

Wear resistant and corrosion materials were proved to extend the wear life with lower cost. 

Diverse selections of shaft seals tailored to each specific application

Expeller Seal  -- Dry Seal: no need for flushing water [Figure 1]

Gland Seal  -- Wet Seal: clean flushing water is necessary [Figure 2]

Mechanical Seal--Wet Seal:clean flushing water is necessary

Upgraded technology of “WRT" type of impeller and throat-bush combination [Figure4] designed to enhance efficiency, lower NPSHr and improve wear performance.

Typical Applications

Flotation process in metal processing plant: regrinding, flotation 

Tailings long-distance Transport

Cyclone Feeding

Wet Crushers

(Ball) Mill Discharge

Coarse sand

In terms of manufacturing technology, the heavy-duty slurry pump adopts advanced manufacturing technology and materials to ensure its characteristics of wear resistance, corrosion resistance, high efficiency and energy saving. Common manufacturing processes include:

Flow channel design: through reasonable design of the flow channel structure, the internal resistance of the slurry pump can be reduced and the fluid transportation efficiency can be improved.
Material selection: Use high wear-resistant and corrosion-resistant materials, such as high-chrome alloys, rubber, etc., to prolong the service life of the pump.
Forming process: Casting or forging process is adopted to ensure the overall structural strength and sealing of the pump.
Assembly process: Strictly control the assembly quality of parts to ensure the stability and reliability of the pump.
