• Energy-efficient due to state-of-the-art pump hydraulics and the use of IE3 motors
• Cataphoretic coating of all Cast Iron components maintains high resistance to corrosion and long service life
• Universal use in diverse applications thanks to different impeller materials, several motor options as well as different mechanical seals
• Easy Installation manual due to standard pump support feet and optional supporting blocks
• Easy maintenance and user-friendly design with optional “back pull-out” design and cartridge mechanical seal for large pump types

Highly efficient high-pressure multistage centrifugal pump in vertical design with in-line connections.

The non self-priming high-pressure multistage centrifugal pump has a compact overall design and is particularly efficient and easy to maintain. The pump shaft and the motor shaft of the IEC standard motor are connected by means of a clamp coupling.

A separate lantern roller bearing ensures optimum admission of axial thrusts. Intermediate bearings in the hydraulics and corrosion-resistant shaft due to Stainless Steel sleeve ensure a long service life. Special, permanently attached lifting eyes enable easy pump installation.

The pump is suitable for water supply, water distribution and pressure boosting, industrial recirculation systems, process water and closed cooling circuits. It can also be used in fire extinguishing systems, washing systems as well as for irrigation.

Special features/product advantages

• Efficiency-optimised, laser-welded 2D/3D hydraulics, flow and degassing optimised
• Corrosion-resistant impellers, guide vanes and stage housings
• Flow and NPSH-optimised pump housing
• Maintenance-friendly design with particularly robust coupling guard
• Drinking water approval for pumps with parts that come in contact with the fluid made of Stainless Steel (EPDM version)
