The unit draws from 4-inch boreholes while handling sand concentrations up to 150 g\/m³, and supports continuous operation for garden watering, tank filling, and rural pressure boosting.\u003c\/p\u003e\u003cp\u003eDelivering up to 118 metres of head at 25 litres per minute, the hydraulic section is driven by a 0.55 kW three-phase motor at 415V. A NEMA-standard flange coupling provides connection to compatible submersible motors. Radial floating impellers in NORYL® allow axial movement to accommodate sand passage, reducing wear on the polycarbonate diffusers in sediment-bearing groundwater.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with an integrated non-return valve in the delivery casing to prevent column drainage. The EASYMAT drive maintains constant pressure by varying motor speed as demand changes, with protection against dry-running, overcurrent, overvoltage, undervoltage and closed outlet. Class F insulation and IP68 rating support continuous submersion in water up to 35°C.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003eFloating impellers manufactured from NORYL® allow sand to pass through without binding the stages\u003c\/li\u003e\r\n\u003cli\u003eExternal jacket constructed from AISI 304 stainless steel for corrosion resistance in borehole environments\u003c\/li\u003e\r\n\u003cli\u003eEASYMAT variable speed drive responds to changing demand by adjusting motor speed automatically\u003c\/li\u003e\r\n\u003cli\u003eSuction strainer in chrome-nickel steel prevents debris from reaching the internal hydraulic components\u003c\/li\u003e\r\n\u003cli\u003eNon-return valve integrated into the delivery casing stops reverse flow when the pump shuts down\u003c\/li\u003e\r\n\u003cli\u003ePolycarbonate diffuser stages maintain smooth water flow through the hydraulic assembly\u003c\/li\u003e\r\n\u003cli\u003eNEMA-standard motor coupling enables straightforward installation and future servicing\u003c\/li\u003e\r\n\u003cli\u003eClass F insulation together with IP68 enclosure supports continuous duty in submerged boreholes\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50985369993463,"sku":"BSM1V1 4SDP-1\/19-EMT","price":3052.78,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm1v1-4sdp-1-19-stainless-steel-4-inches-submersible-bore-pump-domestic-water-supply-easymat.png?v=1785405950","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm1v1-4sdp-1-19-stainless-steel-4-inches-submersible-bore-pump-domestic-water-supply-easymat","provider":"Foundation Pumps","version":"1.0","type":"link"}
