Non-self-priming, high-efficiency multistage high-pressure centrifugal pump in vertical design with in-line connections
Tender text
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 particularly compact overall design. 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. The pump housing and lantern are cataphoretic-coated. Special, permanently attached lifting eyes enable easy pump installation. The pump is suitable for water supply and pressure boosting (selection of the Helix variant depends on the local regulations), industrial recirculation systems, process water and cooling water 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 *Corrosion-resistant impellers, guide vane apparatuses and stage housings *Flow and degassing-optimised hydraulic parts *Reinforced pump housing, flow and NPSH optimised *Space-saving and easy maintenance due to the compact design *Particularly sturdy coupling guard Scope of delivery *Wilo-Helix FIRST V high-pressure multistage centrifugal pump *Installation and operating instructions *Counter flanges of cast iron with the corresponding screws, nuts and gaskets for PN16 pump version with oval flanges Design notes *Variant approved for drinking water on request *Motor protection is to be provided on request or onsite. *In its standard position, the terminal box is aligned with the suction flange, but this can be changed if necessary. *The Wilo-Helix FIRST V is equipped with a standard mechanical seal *Counter flanges are available as accessories. *Bypass sets are available as accessories.
