DAB designed it for recirculating water in ponds and for driving waterfalls and water features, and rates it explicitly for continuous operation, which is a different specification from an intermittent sump or utility pump that expects to sit idle between cycles. The pump body, top body, base, impellers and suction grid are hydro resistant technopolymer with wear-free impellers, the upper and lower motor casings are cast aluminum, the rotor shaft is AISI 416 stainless steel and the seal is a triple lip design in NBR. The motor is a continuous duty asynchronous submersible type with thermal overload protection and a wear-resistant shaft. Both versions in this listing ship with a 100 ft SJTOW cord, which is what lets the pump sit at the far end of a pond and still reach a GFCI receptacle. There is no float switch on either version.\u003c\/p\u003e\u003cp\u003eNOVA 4100 handles clean water without fibres carrying particles up to 0.393 in, and mounts either vertically or horizontally, so it can lie flat on a pond floor or stand in a vault. Typical duty is pond and water garden recirculation, waterfalls, streams, spillways, fountains and architectural water features, plus continuous turnover in tanks and basins. Choose the 115 V version for a standard North American 15 A circuit, or the 230 V version where a 230 V supply is already available and you want the lower running current of 3.2 A.\u003c\/p\u003e\u003ch3\u003eAvailable Models\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNOVA 4100 115 V: 0.5 HP nominal output, no float, max flow 3600 GPH (60 GPM), max head 31.2 ft, 7.1 A, 100 ft SJTOW cord\u003c\/li\u003e\n\u003cli\u003eNOVA 4100 230 V: 0.5 HP nominal output, no float, max flow 3600 GPH (60 GPM), max head 31.2 ft, 3.2 A, 100 ft SJTOW cord\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePower supply: single phase 1 x 110-127 V, 60 Hz, or single phase 1 x 220-240 V, 60 Hz\u003c\/li\u003e\n\u003cli\u003ePower input P1: 0.9 HP, 670 W\u003c\/li\u003e\n\u003cli\u003eNominal output P2: 0.5 HP, 380 W\u003c\/li\u003e\n\u003cli\u003eRated current: 7.1 A at 115 V, 3.2 A at 230 V\u003c\/li\u003e\n\u003cli\u003eMaximum flow: 3600 GPH, which is 60 GPM\u003c\/li\u003e\n\u003cli\u003eMaximum head: 31.2 ft at zero flow\u003c\/li\u003e\n\u003cli\u003eDuty points published by DAB in its NOVA 4100 USA technical sheet: 31.2 ft at 0 GPH, 30.2 ft at 300 GPH, 28.9 ft at 600 GPH, 27.3 ft at 900 GPH, 25.6 ft at 1200 GPH, 23.5 ft at 1500 GPH, 21.2 ft at 1800 GPH, 18.7 ft at 2100 GPH, 15.9 ft at 2400 GPH, 12.9 ft at 2700 GPH, 9.6 ft at 3000 GPH, 6.0 ft at 3300 GPH, 2.3 ft at 3600 GPH\u003c\/li\u003e\n\u003cli\u003eFamily operating range: 1.4 to 60 GPM with head up to 31 ft, per DAB's May 2025 USA catalog\u003c\/li\u003e\n\u003cli\u003eDischarge connection: 1-1\/4 in\u003c\/li\u003e\n\u003cli\u003eMaximum particle size: 0.393 in\u003c\/li\u003e\n\u003cli\u003ePumped liquid: clean water, without fibres\u003c\/li\u003e\n\u003cli\u003eMaximum submersion: 22 ft\u003c\/li\u003e\n\u003cli\u003eLiquid temperature: 32 F to 95 F\u003c\/li\u003e\n\u003cli\u003eEnclosure: IP 68\u003c\/li\u003e\n\u003cli\u003eMotor insulation class: F\u003c\/li\u003e\n\u003cli\u003ePower cord: 100 ft SJTOW\u003c\/li\u003e\n\u003cli\u003eOverall height 12.8 in, body 6.1 in by 5.5 in\u003c\/li\u003e\n\u003cli\u003eMaterials, from the materials table of DAB's NOVA 4100 USA technical sheet: technopolymer pump body, top body, base and impeller; 30 percent glass-filled polypropylene spacer body; cast aluminum upper and lower motor casings; AISI 416 stainless steel rotor shaft; NBR 70 O rings and triple lip seal; stainless steel 316 DIN 982 lock nut\u003c\/li\u003e\n\u003cli\u003eInstallation: vertical or horizontal\u003c\/li\u003e\n\u003cli\u003eCertification: in compliance with CSA Standards C22.2 No. 108-14 and UL Standard No. 778, per DAB's May 2025 USA catalog\u003c\/li\u003e\n\u003cli\u003eShipping weight: 14.8 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRated by DAB for continuous operation, not intermittent cycling\u003c\/li\u003e\n\u003cli\u003e100 ft SJTOW cord reaches a receptacle from the far side of a pond\u003c\/li\u003e\n\u003cli\u003eWear-free technopolymer impellers and a wear-resistant motor shaft\u003c\/li\u003e\n\u003cli\u003eCast aluminum motor casings with a triple lip seal\u003c\/li\u003e\n\u003cli\u003eMounts vertically or horizontally\u003c\/li\u003e\n\u003cli\u003ePasses particles up to 0.393 in\u003c\/li\u003e\n\u003cli\u003eThermal overload protection built into the motor\u003c\/li\u003e\n\u003cli\u003eAvailable in 115 V and 230 V, 60 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePond and water garden recirculation\u003c\/li\u003e\n\u003cli\u003eWaterfalls, streams and spillways\u003c\/li\u003e\n\u003cli\u003eFountains and architectural water features\u003c\/li\u003e\n\u003cli\u003eContinuous turnover in tanks and holding basins\u003c\/li\u003e\n\u003cli\u003eAeration and filtration loop feed\u003c\/li\u003e\n\u003cli\u003eLong-run installations where the receptacle is far from the water\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Valley Milan","offers":[{"title":"115V\/60Hz, 100 ft SJTOW","offer_id":52945983799607,"sku":"DAB60176098","price":452.0,"currency_code":"USD","in_stock":true},{"title":"230V\/60Hz, 100 ft SJTOW","offer_id":52945983832375,"sku":"DAB60178448","price":452.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/dab-nova-4100-continuous-circulation-pump-1.jpg?v=1788482495","url":"https:\/\/www.blacklabelsupply.io\/products\/dab-nova-4100-continuous-circulation-pump","provider":"BLACK LABEL","version":"1.0","type":"link"}
