The DDP4-VARI is a \u003cstrong\u003evariable speed delivery pump\u003c\/strong\u003e that reads demand and adjusts on the fly—speeding up as more valves open and easing back as they close—to maintain \u003cstrong\u003e55 PSI\u003c\/strong\u003e at up to \u003cstrong\u003e4 GPM\u003c\/strong\u003e.

The \u003cstrong\u003e1\/2\" OD tube\u003c\/strong\u003e ports make it an easy inline fit, and the intermittent duty cycle suits start-stop delivery rather than nonstop recirculation. Thermal shutdown protects the motor if it overheats, and an automatic shutoff trips after about two minutes of wide-open flow—handy insurance against a left-open valve or a line that pops loose.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Speed Motor:\u003c\/strong\u003e Digitally adjusts flow to hold 55 PSI as valves open and close.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4 GPM Max Flow:\u003c\/strong\u003e Feeds multiple valves or zones at once from a storage tank.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Pressure Cutoff (60 PSI):\u003c\/strong\u003e Stops the pump from over-pressurizing charged lines.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Shutdown + Auto Shutoff:\u003c\/strong\u003e Motor protection plus a ~2-minute wide-open-flow safety stop.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1\/2\" OD Tube Ports:\u003c\/strong\u003e Drops inline on standard 1\/2\" delivery plumbing.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e115V \/ 1.6A:\u003c\/strong\u003e Standard household power with low current draw for intermittent delivery duty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n      \u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n      \u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eMax Flow Rate\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003e4 GPM\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eMax Output Pressure\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003e55 PSI\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eHigh Pressure Cutoff\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003eYes (60 PSI)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eStandard Voltage\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003e115V, 60Hz, 1 PH\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eAmp Draw\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003e1.6A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003ePort Size (In\/Out)\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003e1\/2\" OD Tube\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eDuty Cycle\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003eIntermittent\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eDimensions (L x W x H)\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003e5.25\" x 6.70\" x 3.93\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#fff;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003e7.4 lbs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f9f9f9;\"\u003e\n      \u003ctd style=\"padding:8px;\"\u003eSKU\u003c\/td\u003e\n      \u003ctd style=\"padding:8px;\"\u003eDDP-4-Vari\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"GrowoniX","offers":[{"title":"Default Title","offer_id":48383847006422,"sku":"DDP-4-Vari","price":369.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Growonix_4_GPM_variable_speed_delivery_pump.webp?v=1782780307","url":"https:\/\/growershouse.com\/products\/growonix-4-gpm-variable-speed-delivery-pump","provider":"GrowersHouse","version":"1.0","type":"link"}
