Nutrient delivery systems are only ever as effective as the pump that’s used to power them. For many years now, Newa jet pumps have been growers’ first port of call, and there are good reasons why. In a nutshell, Newa jet pumps move large quantities of liquid quietly and efficiently, and their reliability is unquestioned. If you’re looking for an effective submersible pump, then there’s really no better all-rounder than a Newa jet water pump. The NJ1200 moves 1200 litres of water per hour.
