Drawing a rated current of 2.3 Amps on a single-phase 240v supply, the unit is equipped with a 5 m submersible power cable. The air-filled 2-pole induction motor is designed for stable service and includes built-in overload protection for winding safety.\u003c\/p\u003e\u003cp\u003eClean water transfer and the emptying of tanks, drums, and small reservoirs are the primary applications for this automated unit. It is IP68 rated for submerged operation up to 5 meters and handles liquid temperatures reaching 50°C in vertical installations. This version utilizes an integrated magnetic switch, allowing for automated start and stop control in narrow pits with limited 200 x 230 mm dimensions.\u003c\/p\u003e\u003cp\u003eThe hydraulic design features a semi-open centrifugal impeller that facilitates the passage of suspended solids up to 10 mm. This system provides an open flow path to move liquid efficiently through a 32 mm discharge port, maintaining operational stability in domestic dewatering systems. It is engineered for reliability in applications where suspended particles are limited to small particulates found in clean water sources.\u003c\/p\u003e\u003cp\u003eMaterials include a 304 stainless steel pump casing, motor frame, and impeller paired with an AISI 303 stainless steel shaft. Protection is managed by a mechanical seal in an oil-lubricated chamber featuring Ceramic\/Carbon\/NBR faces and an upper NBR lip seal. The rotating assembly utilizes sealed ball bearings, and all internal gaskets and O-rings are manufactured from NBR rubber to ensure structural integrity and long-term sealing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMagnetic switch enables automated operation in compact sumps where float switches lack clearance.\u003c\/li\u003e\n\u003cli\u003eCeramic\/Carbon\/NBR mechanical seal faces provide reliable sealing in clean water service.\u003c\/li\u003e\n\u003cli\u003eUpper NBR lip seal offers additional protection against moisture at the motor side.\u003c\/li\u003e\n\u003cli\u003eNBR rubber O-rings and gaskets maintain watertight integrity across all housing joints.\u003c\/li\u003e\n\u003cli\u003eCeramic-coated AISI 303 shaft sleeve enhances wear resistance at the seal interface.\u003c\/li\u003e\n\u003cli\u003eBuilt-in capacitor eliminates the need for external starting components.\u003c\/li\u003e\n\u003cli\u003e5-meter H05RN-F power cable with 3-pin plug supports immediate installation.\u003c\/li\u003e\n\u003cli\u003eClass F insulation and IP68 rating protect the motor in submerged conditions.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ebara","offers":[{"title":"Default Title","offer_id":50920276492535,"sku":"171210-6700","price":724.63,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/ebara-best-one-ms-304-stainless-steel-magnetic-switch-drainage-pump-for-clean-water-transfer-with-semi-open-impeller.png?v=1783409540","url":"https:\/\/foundationpumps.com.au\/products\/ebara-best-one-ms-304-stainless-steel-magnetic-switch-drainage-pump-for-clean-water-transfer-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
