Configured with dual parallel multistage pumps, the package balances incoming mains supplies across expanding facilities. This packaged assembly supplies an integrated water boosting solution to prevent pressure dropouts across multi-fixture networks.\u003c\/p\u003e\n\u003cp\u003eOperating across its calibrated hydraulic envelope, the set achieves flow rates up to 240 L\/min. Across elevated vertical distribution lines, the multistage hydraulic wet end generates up to 55.1 metres of maximum shut-off head to overcome static elevation losses. Internal impellers and intermediate stage diffusers are manufactured from AISI 304 stainless steel to maintain fluid purity and hydraulic efficiency. A hard-faced mechanical seal and reinforced casing construction support operating system pressures up to 10 bar (1,000 kPa).\u003c\/p\u003e\n\u003cp\u003eMechanical drive is delivered through a high-efficiency induction motor engineered for continuous plant room operation. Speed regulation is governed by integrated Davey DynaDrive variable frequency converters mounted directly to each motor, continuously matching motor speed to instantaneous draw to stabilize pipeline pressure. The electrical package connects to a 240V supply at 50 Hz drawing a rated current of 2 x 7.2 Amps. Pre-plumbed hydraulic connections feature standardized 2\" BSP ports, rated for clean liquid operating temperatures from 0°C to 40°C.\u003c\/p\u003e\n\u003cp\u003eThe physical assembly features a rigid, vibration-absorbing structural steel baseplate frame. Integrated elastomeric mounts isolate pump vibrations, protecting connected distribution pipework from mechanical stress and acoustic transmission. Engineered and assembled to meet demanding Australasian commercial plumbing standards, the system benefits from comprehensive Davey technical support and readily available nationwide spare parts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum vertical delivery shut-off head up to 55.1 metres\u003c\/li\u003e\n  \u003cli\u003ePeak volumetric clean water delivery flow up to 240 L\/min\u003c\/li\u003e\n  \u003cli\u003eIntegrated variable speed inverter drive modulating speed to maintain constant line pressure\u003c\/li\u003e\n  \u003cli\u003eWetted internal components precision crafted from AISI 304 stainless steel\u003c\/li\u003e\n  \u003cli\u003eDual parallel Davey DD90-11 multistage pumps providing redundant hydraulic capacity\u003c\/li\u003e\n  \u003cli\u003eMaximum casing operating pressure rating of 10 bar (1,000 kPa PN10)\u003c\/li\u003e\n  \u003cli\u003ePre-plumbed suction and delivery manifolds with standardized 2\" BSP pipe connections\u003c\/li\u003e\n  \u003cli\u003eRated full load electrical current draw of 2 x 7.2 Amps\u003c\/li\u003e\n  \u003cli\u003ePermissible clean liquid operating temperature range from 0°C to 40°C\u003c\/li\u003e\n  \u003cli\u003eElectrical supply rating of 240V at 50 Hz\u003c\/li\u003e\n  \u003cli\u003eDual factory-fitted 8L diaphragm pressure tanks (2x 8L) to absorb hydraulic shock\u003c\/li\u003e\n  \u003cli\u003eBacked by Davey 3-year pump end warranty and 2-year inverter drive warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDavey 2MLD Commercial Packaged Booster Skid\u003c\/li\u003e\n  \u003cli\u003e2 x Davey DD90-11 Multistage Pumps with Integrated Variable Frequency Drives\u003c\/li\u003e\n  \u003cli\u003e2 x Factory-Mounted 8L Diaphragm Pressure Vessels (10 bar rated)\u003c\/li\u003e\n  \u003cli\u003eSuction and Delivery Manifolds with Standardized 2\" BSP Connections\u003c\/li\u003e\n  \u003cli\u003eIndividual Isolation Ball Valves and Spring-Loaded Non-Return Check Valves\u003c\/li\u003e\n  \u003cli\u003eFactory-Calibrated Digital Pressure Transducer and Visual Pressure Gauge\u003c\/li\u003e\n  \u003cli\u003eRigid Structural Steel Mounting Baseplate Frame\u003c\/li\u003e\n  \u003cli\u003eComprehensive Manufacturer Technical Manual and Installation Guide\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":52046996340983,"sku":"2MLD90-11-8","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-dynadrive-dd90-11-single-phase-1-05kw-variable-speed-twin-booster-set-8l-tank.png?v=1793866427","url":"https:\/\/foundationpumps.com.au\/products\/davey-dynadrive-dd90-11-single-phase-1-05kw-variable-speed-twin-booster-set-8l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
