Self-Priming Pumps
Construction
Close-coupled self-priming shallow-well pump with built-in
ejector.
A high-quality pump for domestic water supply. Designed with
environmental considerations, featuring a stainless steel casing,
brass alloy impeller with minimal use of plastic materials.
Applications
For drawing water out of a well.
For lifting water containing air or other gases.
For increasing water pressure from flooded suction applications.
As pressure boosting pump for central water systems with low
pressure (follow local specifications if increasing network
pressure).
For garden use.
For washing with a jet of water.
Operating conditions
Liquid temperature: 0 °C to +35 °C.
Ambient temperature up to +40 °C.
Suction lift up to 9 m.
Maximum permissible pressure in the pump casing: 8 bar.
Continuous duty.
Motor
2-pole induction motor, 50 Hz (n ≈ 2800 rpm).
NGX: three-phase 230/400 V ± 10%.
NGXM: single-phase 230 V ± 10%, with thermal protector.
Capacitor inside the terminal box.
Insulation class F.
Protection IP 54.
Classification scheme IE2 for three-phase motors from 0,75 kW.
Constructed in accordance with: EN 60034-1; EN 60034-30.

NGX
Self-Priming Pumps
Features
3.93.122
* Patented
A different pump with new features
An exclusive diffuser design with flow control device* provides for compact construction,
fast self-priming capability and low noise.
Reliable
With new design features the NGX is more robust and forgiving when temporary abnormal
operating conditions may exist.
Compact
The NGX is smaller than conventional pumps of a similar type, allowing for installation in
restricted spaces and providing for easier retrofit applications.
Safe
Fast air evacuation reduces the risk of air-pockets developing at the mechanical seal
preventing the danger of seal failure due to a lack of flushing and cooling.
Better self-priming
The NGX are capable of lifting water from depths of 9 m in less than 4 minutes, offers new
possibilities on suction lift applications and provides better trouble free service on normal
shallow-well suction lift duties, also with a long suction pipe above the water level.
Low noise
The new diffuser and flow control device* guide the fluid from the impeller into the central
part of the pump casing, reducing turbulence and velocity, with effective use of the
surrounding liquid in dampening the noise of flow.
