The HX-4500 submersible pump is suitable, for example, for irrigating smaller systems or can also be used as a circulation pump for the nutrient tank, ebb & flow systems or also for NFT systems - irrigation with capillaries only to a limited extent, as the delivery rate is too low. Regardless of whether it is used to protect against water penetration or to suck out water tanks of any kind, a submersible pump has many areas of application.
