6 Specification texts: Wilo-Economy MHI 22 (3~4 V, EPDM) Multistage, non-self-priming, horizontal high-pressure centrifugal pump in block design with horizontal suction- and vertical pressure port. The pump has a compact design with a continuous motor pump shaft and a bidirectional mechanical seal. The pump is suitable for water supply and pressure boosting, industrial recirculation systems, process water and cooling water circuits. It can also be used in washing systems as well as for irrigation. Special features/product advantages Space-saving, compact block design All hydraulic parts which come into contact with the fluid, such as stage chambers, impellers and diffusors and the pump housing are made of stainless steel Drinking water approval (KTW, WRAS) for all components in contact with the fluid (EPDM version) Scope of delivery Wilo-Economy MHI high-pressure multistage centrifugal pump Installation and operating instructions Design notes Motor protection for three-phase AC motor is optional or to be provided on-site Single-phase AC motor equipped with built-in thermal motor protection and capacitor Materials Impeller:.43 [AISI34] Pump housing:.43 [AISI34] Pump shaft:.43 [AISI34] Static seal: EPDM Mechanical seal: BE3GG Power Fluid temperature: C Max. ambient temperature: 4 C Inlet pressure Max.: 6 bar Motor Insulation class: F Protection class: IP 54 Mains connection: 3~4 V, 5 Hz Nominal motor power:.55 kw Power consumption:.83 kw Nominal current 3~23 V, 5 Hz: 3.
