Non-self-priming, high-efficiency multistage high-pressure centrifugal pump in vertical design with in-line connections
DESCRIPTION_LONG
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 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, while 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) Scope of delivery Wilo-Helix V high-pressure multistage centrifugal pump Installation and operating instructions Design notes Motor protection for 3-phase motor is to be provided on request or onsite Single-phase AC motor equipped with built-in thermal motor protection and capacitor In its standard position, the terminal box is aligned with the suction flange, but this can be changed if necessary The Wilo-Helix V is equipped with a user-friendly mechanical seal in a cartridge design and standard gasket for easy maintenance The spacer coupling (from ≥ 7.5 kW) allows the mechanical seal to be replaced without removing the motor The flexible lantern design, which is available in two alignments, enables direct access to the mechanical seal For pump versions PN16, PN25 and Pmax = 30 bar, round counter flanges in cast iron or stainless steel, screws, nuts and gaskets are available as accessories Bypass sets are available as accessories The Wilo-Helix V(F) VdS certified version upon request
