The unit pairs a Calpeda 4-inch submersible pump with an EASYMAT frequency converter, processing water with sand up to 150 g\/m³ for continuous service.\u003c\/p\u003e\u003cp\u003ePower comes from a 1.5 kW three-phase motor at 415V, achieving 135 metres of head at 70 L\/Min. Within each stage, NORYL® floating impellers move axially to accommodate sand particles, protecting the polycarbonate diffusers from excessive wear in deep-well environments. The NEMA-standard motor coupling provides a standardised mechanical interface for simplified servicing.\u003c\/p\u003e\u003cp\u003eEASYMAT adjusts motor speed to maintain constant pressure, with protection against dry-running, overcurrent, overvoltage, undervoltage and closed outlet. AISI 304 stainless steel forms the external jacket, and a built-in non-return valve in the delivery casing helps protect the internal hydraulics by preventing reverse flow during shutdown.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003eNORYL® floating impeller stages prevent internal wear and binding when pumping sandy water\u003c\/li\u003e\r\n\u003cli\u003eAISI 304 stainless steel jacket resists corrosion in borehole service\u003c\/li\u003e\r\n\u003cli\u003eEASYMAT frequency converter delivers automatic pressure regulation without user intervention\u003c\/li\u003e\r\n\u003cli\u003eChrome-nickel steel suction strainer blocks mineral particles from the intake\u003c\/li\u003e\r\n\u003cli\u003eNon-return valve helps prevent reverse flow and protects against backflow\u003c\/li\u003e\r\n\u003cli\u003ePolycarbonate diffuser stages maintain efficient flow through the hydraulic assembly\u003c\/li\u003e\r\n\u003cli\u003eNEMA-standard coupling simplifies installation with various submersible borehole motors\u003c\/li\u003e\r\n\u003cli\u003eClass F insulation and IP68 protection support continuous duty in deep borehole installations\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50985370747127,"sku":"BSM1V1 4SDP-3\/21-EMT","price":5064.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm1v1-4sdp-3-21-stainless-steel-4-inches-submersible-bore-pump-residential-tank-filling-easymat.png?v=1785405967","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm1v1-4sdp-3-21-stainless-steel-4-inches-submersible-bore-pump-residential-tank-filling-easymat","provider":"Foundation Pumps","version":"1.0","type":"link"}
