This single-phase unit handles liquid temperatures up to 50°C and is particularly suitable for liquids with a high solid content up to 25 mm. The manual (SG) configuration is ideal for continuous duty cycles where automated float switches are not required.\u003c\/p\u003e\u003cp\u003ePowered by a 0.37 kW 240v motor, this model achieves a total head of 7.8 m and a maximum flow rate of 200 L\/min. drawing a rated current of 3.5 Amps, internal cooling is achieved by fluid circulating between the motor jacket and outer shell. This self-cooling design ensures the unit can operate safely during extended drainage run cycles, even when only partially submerged.\u003c\/p\u003e\u003cp\u003eWater passes through a single vortex impeller arranged to move clean or slightly dirty water with high efficiency. The suction filter is integrated into the AISI 304 pump body to protect the hydraulics, while the vertical delivery port configuration assists in streamlined installation. Manual operation allows for the extraction of water down to a residual level of just 30 mm from the floor.\u003c\/p\u003e\u003cp\u003eThe close-coupled construction features an external jacket and motor jacket manufactured from chrome-nickel stainless steel AISI 304. Sealing is managed by a double shaft seal with an oil chamber containing oil for food and pharmaceutical machinery. The induction motor includes an incorporated capacitor, built-in thermal protector, and a triple impregnation humidity-proof dry winding.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eManufactured using AISI 304 stainless steel for the pump casing and motor jacket to ensure long-term durability.\u003c\/li\u003e\n\u003cli\u003eManual configuration (SG) without float switch is suitable for continuous duty in transfer systems.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with an oil-filled chamber provides a robust barrier against water ingress.\u003c\/li\u003e\n\u003cli\u003eMechanical shaft seal lubrication is ensured by pharmaceutical-grade oil within the integrated oil chamber.\u003c\/li\u003e\n\u003cli\u003eInternal motor cooling achieved by the pumped fluid passing between the motor jacket and the external shell.\u003c\/li\u003e\n\u003cli\u003eVortex impeller design enables the passage of suspended solids up to 25 mm without clogging.\u003c\/li\u003e\n\u003cli\u003eIncludes a triple impregnation humidity-proof dry winding designed in accordance with EN 60335-2-41 standards.\u003c\/li\u003e\n\u003cli\u003eCertified IP X8 protection rating facilitates continuous duty immersion at depths reaching up to 5 meters.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50914706424055,"sku":"GXV 25-8 SG","price":848.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-gxv-25-8-sg-stainless-steel-manual-submersible-drainage-pump-standing-water-vortex-impeller.png?v=1783147713","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-gxv-25-8-sg-stainless-steel-manual-submersible-drainage-pump-standing-water-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
