City Borehole Pumps

City 4in and 6in submersible borehole pumps are available in more than 100 models, with motor power up to 40 HP. They rely on quality and value-for-money to maintain their place in the World market.

Now their full range - from 1 cubic meter per hour to 60 cubic metres per hour with heads of over 500 metres - is available to drillers and installers in the UK, exclusively through Amos Pumps.

Single and three-phase versions are available, with up to 3 HP for single phase motors and 40 HP for three phase. All accessories are supplied, including a waterproof heat-shrink cable joint, and, with single-phase models, Amos Pumps own easy to install starter box containing start capacitor and overload cut-out with manual reset.

Amos Pumps also offer a low-level control box, cable and probes for use where there is a risk of damage through dry-running, and a full range of optional extras, making it easy for installers to be sure of all they need from one reliable source.

 

Low-level Control Boxes
Amos' spacious single-phase and three-phase control boxes feature DIN-rail component mounting to ensure easy access and component replacement if needed. Capacitor is included, together with spare terminals so that float switches or pressure sets can be wired in.

Borehole accessories
The Amos Pumps built and designed low-level control box, centre right, with probes, borehole pump cable, support rope and standard borehole pump control box

Motor replacement service
Borehole pump breakdown can lead to loss of production for industrialists and crop damage for growers. Frequently, the problem is traced to motor burn-out, leaving the pump itself still in good condition.

Amos Pumps are saving their customers cash and downtime by offering a speedy motor replacement service for units designed to NEMA standards. Contact our sales office for details.
