Features/Product Advantages
Compact pump design featuring a rigid connection between the motor and pump shaft; eliminates the need for on-site shaft alignment and results in a compact overall footprint.
Low noise and vibration levels during operation ensure stability and effectively reduce operating costs.
Pump casing, impeller, and other components are available in various materials to meet specific application requirements.
Construction
Flanged connection; compact horizontal end-suction centrifugal pump.
Applications
Pumping of clean water or slightly contaminated water (max. 20 ppm solids) for circulation, transfer, and pressure boosting.
Handling of hot water (compliant with VDI 2035 standards), water-glycol mixtures, cooling/chilled water, and industrial process water.
Suitable for municipal water supply, irrigation, building services, general industry, power plants, etc.
Equipment/Functions

Commissioning
This pump series is designed for installation and operation within enclosed spaces only. Typical installation locations include equipment rooms inside buildings that house other building services equipment.
Before commissioning, the pump and electrical components must be allowed to adjust to the ambient temperature.
Properly fill the entire unit with liquid and vent it.
Dry running damages the mechanical seal; ensure the pump does not run dry.
