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\u003eOperating on a three-phase 415 V supply, this pump features a 0.75 kW motor drawing a rated current of 2 Amps. The hydraulic performance curve shows a maximum head of 12 m combined with a maximum flow of 435 L\/Min.\u003c\/p\u003e\n\u003cp\u003eA Semi-open single-channel impeller handles solids up to 45 x 20 mm in size. This solid-handling configuration is combined with 50 mm suction and discharge diameters to promote continuous circulation.\u003c\/p\u003e\n\u003cp\u003eThe gray cast iron casing and impeller are paired with a 420 stainless steel shaft. Internal sealing is achieved through a double mechanical seal in an oil bath, configured with Ceramic-to-Carbon upper and Silicon Carbide-to-Silicon Carbide lower seal faces. An Oil Lifter distributes lubricating oil across the seal faces. The PVC-sheathed power cable incorporates an anti-wicking block, and a built-in Circle Thermal Protector protects the motor.\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":50939493417207,"sku":"50B2.75","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-50b2-75-cast-iron-3-phase-sewage-pump-for-equalization-tanks-with-semi-open-single-channel-impeller.png?v=1784109626","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-50b2-75-cast-iron-3-phase-sewage-pump-for-equalization-tanks-with-semi-open-single-channel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
