It pairs a Calpeda 4-inch submersible pump with an EASYMAT frequency converter, handling sand concentrations up to 150 g\/m³ while maintaining stable pressure for outdoor and indoor supply needs.\u003c\/p\u003e\u003cp\u003eDriven by a 0.55 kW motor at 415V, the hydraulic assembly produces 51 metres of head at 70 L\/Min. 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 secure connection point for standard 4-inch submersible motors.\u003c\/p\u003e\u003cp\u003eEASYMAT variable speed control adjusts pump output to match demand, 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 chrome-nickel steel delivery casing prevents 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 design allows axial displacement to accommodate sand particles\u003c\/li\u003e\r\n\u003cli\u003eAISI 304 stainless steel external jacket offers corrosion resistance in borehole service\u003c\/li\u003e\r\n\u003cli\u003eEASYMAT controller maintains constant pressure by varying motor speed as demand changes\u003c\/li\u003e\r\n\u003cli\u003eChrome-nickel steel suction strainer provides a barrier against solids and debris\u003c\/li\u003e\r\n\u003cli\u003eIntegrated non-return valve in the delivery casing prevents reverse flow when pump stops\u003c\/li\u003e\r\n\u003cli\u003ePolycarbonate diffuser stages direct water effectively through the hydraulic section\u003c\/li\u003e\r\n\u003cli\u003eNEMA-standard coupling ensures compatibility with a wide range of submersible motors\u003c\/li\u003e\r\n\u003cli\u003eClass F insulation and IP68 protection support reliable service in deep borehole installations\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50985370648823,"sku":"BSM1V1 4SDP-3\/8-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-3-8-stainless-steel-4-inches-submersible-bore-pump-garden-irrigation-easymat.png?v=1785405963","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm1v1-4sdp-3-8-stainless-steel-4-inches-submersible-bore-pump-garden-irrigation-easymat","provider":"Foundation Pumps","version":"1.0","type":"link"}
