ZH(R) SERIES

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.
