It moves 5,200 litres an hour on 40 watts. A pond pump runs continuously, so wattage compounds, every 5 W you save is roughly 44 kWh over a year, and at this flow rate the CTP series is among the leanest on the market.\u003c\/p\u003e\n\u003ch3\u003eAmphibious means it runs wet or dry\u003c\/h3\u003e\n\u003cp\u003eMost pond pumps must stay submerged or they burn out. This one can sit in the water or be plumbed in externally alongside the pond, which matters if you want the pump out of the water for easier servicing, or if you are feeding a pressurised filter from a dry chamber. It handles fresh and salt water, so it suits marine tanks and seafood holding systems as well as koi ponds.\u003c\/p\u003e\n\u003ch3\u003eReading the flow and head figures\u003c\/h3\u003e\n\u003cp\u003eThese two numbers describe the pump at opposite extremes. The 5,200 L\/h figure is measured at \u003cstrong\u003ezero head\u003c\/strong\u003e , the outlet level with the water surface. The 4.8 m figure is the \u003cstrong\u003eshut-off head\u003c\/strong\u003e, the height at which the pump can no longer lift water and flow drops to nothing. Actual output falls between the two, declining as lift increases. If you are feeding a waterfall or a filter above pond level, size on the flow you need \u003cem\u003eat your actual lift height\u003c\/em\u003e, not on the headline figure.\u003c\/p\u003e\n\u003ch3\u003eMatching it to your filter\u003c\/h3\u003e\n\u003cp\u003eWorth saying plainly: do not oversize the pump against your filter. Pushing more water through a filter than it is rated for causes it to overflow, and on a pressurised unit it puts the housing under strain. If this pump exceeds what your filter can take, fit a Y-adapter and bleed the excess back into the pond.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum flow: 5,200 L\/h at zero head\u003c\/li\u003e\n\u003cli\u003eMaximum lift (shut-off head): 4.8 m\u003c\/li\u003e\n\u003cli\u003ePower consumption: 40 W\u003c\/li\u003e\n\u003cli\u003eSupply: 220-240 V, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003eHose adaptors: 20 mm, 25 mm and 32 mm\u003c\/li\u003e\n\u003cli\u003eDimensions (L × W × H): 172 × 113 × 126 mm\u003c\/li\u003e\n\u003cli\u003eCable length: 2.5 m\u003c\/li\u003e\n\u003cli\u003eIngress protection: IPX8\u003c\/li\u003e\n\u003cli\u003eShaft: ceramic, corrosion and wear resistant\u003c\/li\u003e\n\u003cli\u003eWater types: fresh and salt water\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGarden ponds and water features\u003c\/li\u003e\n\u003cli\u003eWaterfalls and streams\u003c\/li\u003e\n\u003cli\u003eAquaponics and small aquaculture systems\u003c\/li\u003e\n\u003cli\u003eFeeding gravity and pressurised pond filters\u003c\/li\u003e\n\u003cli\u003eHydroponic and recirculating systems\u003c\/li\u003e\n\u003cli\u003eMarine tanks and seafood holding systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eServicing\u003c\/h3\u003e\n\u003cp\u003eThe pump strips down by hand for cleaning — no tools, no specialist parts.
