The unit combines a Calpeda 4-inch submersible pump with an EASYMAT frequency converter, handling sand up to 150 g\/m³ for continuous operation.\u003c\/p\u003e\u003cp\u003eProducing 43 metres of head at 100 L\/Min, the hydraulic assembly is powered by a 0.55 kW motor at 415V. NORYL® floating impellers move axially against polycarbonate diffusers, preventing binding when sand is present and maintaining performance over years of service. The NEMA-standard mechanical interface provides a reliable connection point for standardised submersible motors.\u003c\/p\u003e\u003cp\u003eEASYMAT variable speed control maintains constant pressure as demand varies, with protection against dry-running, overcurrent, overvoltage, undervoltage and closed outlet. AISI 304 stainless steel forms the external jacket, with a chrome-nickel steel delivery casing incorporating a non-return valve to prevent column drainage and reverse flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003eNORYL® floating impeller stages reduce internal binding risk when pumping sandy water\u003c\/li\u003e\r\n\u003cli\u003eAISI 304 stainless steel jacket provides corrosion resistance for borehole installations\u003c\/li\u003e\r\n\u003cli\u003eEASYMAT controller automatically stabilises pressure across varying flow conditions\u003c\/li\u003e\r\n\u003cli\u003eChrome-nickel steel suction strainer prevents solids from entering the stages\u003c\/li\u003e\r\n\u003cli\u003eNon-return valve in the delivery casing stops reverse flow and protects the motor\u003c\/li\u003e\r\n\u003cli\u003ePolycarbonate diffuser stages guide water effectively through the hydraulic assembly\u003c\/li\u003e\r\n\u003cli\u003eNEMA-standard motor coupling enables flexible pairing with various submersible motors\u003c\/li\u003e\r\n\u003cli\u003eClass F insulation and IP68 enclosure support reliable performance under continuous immersion\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50985370812663,"sku":"BSM1V1 4SDP-4\/7-EMT","price":4607.68,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm1v1-4sdp-4-7-stainless-steel-4-inches-submersible-bore-pump-water-transfer-easymat.png?v=1785405971","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm1v1-4sdp-4-7-stainless-steel-4-inches-submersible-bore-pump-water-transfer-easymat","provider":"Foundation Pumps","version":"1.0","type":"link"}
