It’s very satisfying to get water flowing from a new or refurbished borehole. But as time goes on, the pump driving it may be straining itself and draining energy far more than is good for its health and your pocket. 
Typically, this is life with a fixed pressure pump. As water demand increases, it loses pressure. As demand drops, it overworks and risks running dry. Soon you can be facing repeated trouble-shooting, that could progress to premature failure and the prospect of an expensive refit.

Benefits that keep stacking up  

With a built-in inverter that automatically adjusts around water demand, the NASTEC 4HS ensures constant pressure to your tap, sprinkler and exchangers linked to supported systems:

• Changes pump speed to maintain set-pressure even during peak water demand
• Intelligent control saves energy and extends pump life
• Gentle pump starts and stops reducing mechanical stress
• Pump and drive protected from overload, surges, dry running and voltage variations
• Number of pump stages is a quarter of traditional 50 Hz
• Mono-block single shaft reduces vibration for silent, smooth operation and extended motor life.
• Variable speed means one pump can cover a wider range of hydraulic performance, allowing reduction in the pump variations you need to stock
• Motor constructed for high thermal conductivity allowing safe use in pumping high-temperature water.
• Built-in inverter module designed for high thermal conductivity for extended life from electronic components and greater mechanical resistance to vibration and external pressure

The Nastec 4HS is as close to a fit-and-forget pump as you would want – because every borehole, as smoothly as it may run, needs routine health-checks.
Security for you, your client as well as for the systems and people who depend on your borehole

Dramatic as it may sound, an inadequate wellhead can land both contractor and owner with a criminal conviction and hefty costs if it leads to groundwater pollution.

Despite the prospect of up to £20,000 fines and legal action that could ruin businesses and reputations, too many boreholes are ticking time-bombs of potential health and water contamination issues. 
 

As Environment Agency guidance reveals: “..staff have seen many examples of badly constructed, completed or maintained private water supply boreholes, and are concerned at the risks to which source owners are subjecting themselves, often out of ignorance.”
 

However, ignorance is no defence if a wellhead is found to be the culprit of a problem warranting Agency inspection. 

It is a criminal offence to “cause or knowingly permit” groundwater to become polluted, with heavy penalties (£20,000 maximum fine in a magistrates court, or an unlimited fine and/or imprisonment on indictment).

There’s every pressure to get your wellheads right, but the reality is, they can be a hassle.
 

Borehole installations at the surface present very differently, meaning off-the-shelf products don’t always guarantee a perfect fit. It can be time-consuming and tricky to get a firm interface and good seal when making up solutions on site.
 

Now you can assure hard-wearing, hygienic and compliant protection of your wellhead for far less than you think, with Proquip’s new Polypropylene (PP) Wellheads.
 

Compact, robust and purpose-made, they’ll save you time and money while delivering all the quality and performance associated with the Proquip product stable.
 

Add our mild steel and stainless steel options, plus bespoke wellhead assemblies, Proquip has every size, type and configuration of domestic or commercial borehole covered.
