{"product_id":"iws-tank-pump","title":"IWS Tank Pump – Flood and Drain Replacement Pump","description":"\u003ch2\u003eThe Right Pump for the Tank End of an IWS System\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eIWS Tank Pump\u003c\/strong\u003e is the genuine replacement for the pump that sits in the reservoir of an IWS system and sends solution to the brain or the dripper line. Each is a NEWA pump made in Italy on a \u003cstrong\u003elong lead\u003c\/strong\u003e, so it can sit on the tank floor with the cable run neatly out of the top. The \u003cstrong\u003eMJ1000\u003c\/strong\u003e and \u003cstrong\u003eNJ3000\u003c\/strong\u003e flood and drain pumps are wired with the \u003cstrong\u003eblue IWS (Bulgin) connector\u003c\/strong\u003e and come with a tank grommet, so they plug straight into an IWS brain: the MJ1000 for 16mm Standard and Standard Remote systems, the NJ3000 for 25mm Pro systems. The \u003cstrong\u003eNJ6000\u003c\/strong\u003e is the long-lead pump IWS supply for the Dripper tank. A tired pump shows up as slow, part-filled floods or weak drippers at the end of the line - uneven feeding that soon costs growth - so a matched spare keeps the system running as designed.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine IWS assemblies\u003c\/strong\u003e, matched to the IWS brain or dripper tank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-in fit\u003c\/strong\u003e: blue IWS connector on the MJ1000 and NJ3000 runs straight from the brain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong lead\u003c\/strong\u003e for a tidy run out of the reservoir\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree outputs\u003c\/strong\u003e: \u003cstrong\u003e1,000 L\/h\u003c\/strong\u003e, up to \u003cstrong\u003e3,000 L\/h\u003c\/strong\u003e and \u003cstrong\u003e6,000 L\/h\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubmersible and sealed\u003c\/strong\u003e (IP68 on the MJ1000 and NJ3000), made in Italy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIsolate the system and lift out the old pump; clean the tank floor\u003c\/li\u003e\n\u003cli\u003eStand the new pump on the floor of the tank and fit its outlet to the fill pipe\u003c\/li\u003e\n\u003cli\u003eSeat the grommet where the lead leaves the tank and plug the connector into the brain\u003c\/li\u003e\n\u003cli\u003eRun a test flood with plain water and check the flow before adding nutrients\u003c\/li\u003e\n\u003cli\u003eClean the inlet guard regularly and never run the pump dry\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow rate (L\/h):\u003c\/strong\u003e 1,000 \/ 3,000 \/ 6,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax head (m):\u003c\/strong\u003e 1.48 \/ 2.9 \/ 3.6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower (W):\u003c\/strong\u003e 13 \/ 55 \/ 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet (mm):\u003c\/strong\u003e 12.6 \/ 21.4-26.9 (3\/4\") \/ 25-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e IWS (NEWA pumps)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMJ1000 (Standard 16mm):\u003c\/strong\u003e NEWA Maxi-Jet MJ1000, 1,000 L\/h, 13W, max head 1.5m, IP68, max water 35°C, long lead with blue IWS connector and grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNJ3000 (Pro 25mm):\u003c\/strong\u003e NEWA Jet NJ3000, 1,200-3,000 L\/h, 55W, max head 2.9m, IP68, max water 35°C, long lead with blue IWS connector and grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNJ6000 (Dripper):\u003c\/strong\u003e NEWA Jet NJ6000 long-lead pump for the IWS Dripper tank, 6,000 L\/h, 70W, max head 3.6m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply:\u003c\/strong\u003e 220-240V, 50Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e Italy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cdiv class=\"hcs-faq\"\u003e\n\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eWhich pump does my system need?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eIWS Standard and Standard Remote (16mm) systems use the MJ1000; Pro (25mm) flood and drain systems use the NJ3000; the NJ6000 is the long-lead pump IWS supply for the Dripper tank.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eWill these pumps plug into a normal socket?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eThe MJ1000 and NJ3000 are fitted with the blue IWS connector to run from an IWS brain, not a standard UK plug.
