PHZ

Summary

Product identification

The PHZ is a vertical tubular casing pump.

Applications:

• Provision of seawater for desalination systems
• Cooling water systems in power stations and industrial plants
• Water extraction for flue gas desulphurisation
• Water extraction and drainage in low-list pumping stations

Operating limits

• Max. flow rate: 18 m³/s
• Max. head: 25 m
• Max. fluid temperature: 40 °C
• Max. speed: 980 min⁻¹

*Higher flow rates, pump heads, and temperatures are available on request.

In addition, active cathode protection is available for stainless steel pumps and sacrificial anodes for steel pumps with coating.

Mechanical / hydraulic

• Bearings: Every pump comes with KSB‘s specially developed RESIDUR® bearings, which are wear-resistant, maintenance-free, and medium-lubricated. An alternative design with polymer plastic bearings (Thordon) is possible.
• Adjustment: Economically efficient adjustment to match changes in system conditions (flow rate/head) is possible by adjusting the axial propeller both during operation and during standstill.
• Design variants: Pumps are available in pull-out design, allowing straightforward removal and maintenance of all wear parts.
• Customization: Customised pump designs are available, adapted to existing structures and systems. Various customised solutions with special elbow angles, seals, 45-degree horizontal pumps, and floor installation are possible.
