The unit combines a Calpeda 4-inch submersible pump with an EASYMAT frequency converter, handling sand up to 150 g\/m³ for continuous service.\u003c\/p\u003e\u003cp\u003eProducing 23 metres of head at 220 L\/Min, the hydraulic assembly is driven by a 0.75 kW motor at 415V. NORYL® floating impellers move axially within each stage to accommodate sand particles, protecting the polycarbonate diffusers from wear during high-capacity transfer duty. The NEMA-standard mechanical interface provides a secure 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, and a delivery casing incorporates a non-return valve to prevent backflow during shutdown.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003eSpecial radial floating impellers provide enhanced sand handling for sandy boreholes\u003c\/li\u003e\r\n\u003cli\u003eAISI 304 stainless steel jacket resists corrosion in borehole environments\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 prevents debris from entering the stages\u003c\/li\u003e\r\n\u003cli\u003eIntegrated non-return valve protects against backflow and water column weight\u003c\/li\u003e\r\n\u003cli\u003ePolycarbonate diffuser stages maintain efficient water flow through the hydraulic section\u003c\/li\u003e\r\n\u003cli\u003eNEMA-standard coupling ensures compatibility with standardised submersible motors\u003c\/li\u003e\r\n\u003cli\u003eClass F insulation and IP68 protection support continuous operation in submerged boreholes\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50985371107575,"sku":"BSM1V1 4SDP-8\/4-EMT","price":4611.42,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm1v1-4sdp-8-4-stainless-steel-4-inches-submersible-bore-pump-agricultural-irrigation-easymat.png?v=1785405985","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm1v1-4sdp-8-4-stainless-steel-4-inches-submersible-bore-pump-agricultural-irrigation-easymat","provider":"Foundation Pumps","version":"1.0","type":"link"}
