NGX 4/18, a different jet pump with new features:
With an exclusive diffuser and flow control device, the NGX features a compact construction, fast self-priming and low noise operation.
Reliable: With its new design, the NGX is more durable in the event of temporary abnormal operating conditions.
Compact: The NGX is smaller than a conventional pump of the same type.
This makes it possible to install it in smaller spaces and to more easily replace an existing pump.
Safe: The rapid evacuation of air reduces the risk of an air pocket forming around the mechanical seal.
Safer against the danger of mechanical seal failure due to lack of lubrication and cooling.
More self-priming: the NGX are able to lift water from a depth of 9 m in less than 4 minutes.
This opens up new possibilities for use with the higher suction heights and safer operation in installations with normal suction heights for shallow wells, even with a long section of suction pipe above the water level.
Low noise: the new diffuser and flow control device guides the fluid from the impeller into the central part of the pump body reducing its speed and turbulence, effectively using the surrounding liquid to dampen the noise of the flow.
