The unit is compatible with free standing discharge bends and duckfoot bend guide rail fitting systems, enabling routine installation and retrieval. It is rated for continuous duty in liquids from 0 to 40°C.\u003c\/p\u003e\n\u003cp\u003eA 1.5 kW dry-type induction motor runs on a three-phase 415 V electrical supply to power the unit. With a rated current of 3.5 Amps, this pump achieves a maximum head of 16.9 m and a maximum flow rate of 1000 L\/Min.\u003c\/p\u003e\n\u003cp\u003eThe hydraulic design incorporates a Semi-open single-channel impeller with a solids passage size of 49 x 41 mm to prevent clogging. Suction and discharge openings are both sized at 80 mm to accommodate fluid flow without internal restrictions.\u003c\/p\u003e\n\u003cp\u003eConstructed with a gray cast iron casing and impeller, the pump incorporates a 420 stainless steel shaft. A double inside mechanical seal in an oil chamber utilizes Ceramic-to-Carbon upper and Silicon Carbide-to-Silicon Carbide lower seal faces. Tsurumi's original Oil Lifter supplies lubricating oil to the seal faces, while a watertight cable entry with an anti-wicking block protects the motor. Motor safety is maintained by a built-in Circle Thermal Protector.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGray cast iron construction offers robust casing and impeller casing wear resistance for long-term submergence.\u003c\/li\u003e\n\u003cli\u003eSemi-open single-channel impeller with dynamically balanced design for solid-handling configuration.\u003c\/li\u003e\n\u003cli\u003eDouble inside mechanical seals in oil chamber featuring Ceramic-to-Carbon upper and Silicon Carbide-to-Silicon Carbide lower.\u003c\/li\u003e\n\u003cli\u003ePatented Oil Lifter technology supplies lubrication to the mechanical seal faces even if the oil level drops.\u003c\/li\u003e\n\u003cli\u003eWatertight PVC cable entry with integrated anti-wicking block protects the motor from capillary water ingress.\u003c\/li\u003e\n\u003cli\u003eBuilt-in Circle Thermal Protector directly cuts the motor circuit or alerts control systems in overheating conditions.\u003c\/li\u003e\n\u003cli\u003ePermanently lubricated, deep-groove, double-shielded C3 ball bearings support continuous-duty operation.\u003c\/li\u003e\n\u003cli\u003eDual discharge configuration supports both free standing bend sets and duckfoot guide rail fitting systems.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50939493482743,"sku":"80B21.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80b21-5-cast-iron-three-phase-sewage-pump-for-flood-control-with-semi-open-single-channel-impeller.png?v=1784109630","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80b21-5-cast-iron-three-phase-sewage-pump-for-flood-control-with-semi-open-single-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
