Just a quick note to bring you up to date on progress with our submersible bore pump installation program. As you know, we have now completed over 50 installations where we have installed a Maric Flow Restrictor on the discharge headworks to ensure that the pump is operating within the normal range on the pump curve.

Many of our bore pump installations have a standing water level of around 10 meters from the surface and consequently, when the pump starts, the potential for cavitation and running off the end of the curves guaranteed. By installing the appropriate flow restrictor, we have eliminated this problem completely and so the pumps will be able to operate safely for many years.

The flow restrictors have proven to be easy to install and accurate so I have no hesitation in recommending the product to any potential user.
