The ESPA NOX 20 pump belongs to the popular NOX series, which is characterised by a compact construction and a long service life. The all-plastic pump section resists corrosion and the aggressive environment of pool chemistry.
The AISI 420 stainless steel shaft provides mechanical strength and resistance to oxidation, while sealing is performed by a reliable graphite mechanical seal that minimises the risk of water leakage. The electric motor housing is surface-treated and made of aluminium alloy, thanks to which the pump dissipates heat well even during long-term operation.
The self-priming capability facilitates the first start-up and prevents problems during a short-term drop in level in the pre-filter chamber. With a flow rate of 4 m³/h, this model is suitable for the filtration circuits of smaller and medium-sized pools, where reliability at an acceptable price is key.
