{"product_id":"674335-01","title":"Multiquip 674335-01 Shaft Sleeve 35mm x 25 x 21 - OEM Replacement Part","description":"\u003cp\u003eThis precision-machined shaft sleeve protects the motor shaft and supports proper impeller alignment in Multiquip submersible centrifugal pumps. The shaft sleeve maintains critical spacing between the impeller and motor components, preventing shaft wear and ensuring optimal pump performance in demanding water pumping applications including standing water drainage, excavation dewatering, and industrial wastewater transfer.\u003c\/p\u003e\n\n\u003cp\u003eThe 674335-01 shaft sleeve is essential during impeller maintenance procedures outlined in Multiquip service manuals. When removing the impeller for inspection or replacement, this sleeve must be examined for wear, scoring, or damage. Given the high-performance operation of these pumps—with maximum heads of 138 feet and flow rates up to 423 gallons per minute—the shaft sleeve operates under significant mechanical stress and should be replaced if any degradation is visible to prevent impeller wobble or shaft damage.\u003c\/p\u003e\n\n\u003cp\u003eThis shaft sleeve is designed for the ST4 series submersible pumps featuring chrome steel impellers, double mechanical seals in oil chambers, and heat-treated 420J2 stainless steel output shafts. The precise 35mm x 25 x 21 dimensions ensure proper fit and alignment within the pump assembly.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eST41230 (230V, 3-Phase, 4\" Submersible Pump)\u003c\/li\u003e\n\u003cli\u003eST41460 (460V, 3-Phase, 4\" Submersible Pump)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Multiquip OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Multiquip","offers":[{"title":"Default Title","offer_id":43066621952048,"sku":"674335-01","price":117.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/674335-01.png?v=1779816056","url":"https:\/\/cce-industries.com\/products\/674335-01","provider":"CCE Industries","version":"1.0","type":"link"}
