Garry Grant, Director at Hydro Innovations, with his training centre’s indoor pumping station.

Since 2008, Hydro Innovations has been cultivating an extensive range of products and now, with its new training centre, its capable staff are able to pass some of their expertise on to you in a truly impressive way.

Hydro Innovations' Wastewater Pumping Station

This is the centre-piece of the training centre: a fully operational installation of a Gorman-Rupp ES 200x200 sewage and wastewater pumping station. The installation stretches across two floors, with separate observation areas for the above-ground pump enclosure, and the below-ground piping where all the action happens.

The upper section has a full size working standard pumping station; two Gorman-Rupp Ultra-V sewage pumps sit inside a low profile housing, accessible from two wide-opening hatches. This is the heart of the installation, where the pumps provide the power needed to move 40 litres of water per second.

The below-ground section is where the demonstration really comes to life. There, thanks to custom-fitted sections of transparent plastic pipes and siding, the audience can see tonnes of water flowing right past them, cycling into of the temporary reservoir/wet well before being pumped away by the aforementioned Ultra-V pumps.

The internal workings of the installation are also monitored by an electronic system which displays the data through an easy-to understand computer interface. Trainees can see everything from the flow rate and pump speed to the suction and discharge pressures, all displayed on a large wall-mounted screen.


Cutaway Self-Priming Centrifugal Pump

Hydro’s training centre also holds another cutaway demonstration model; a self-priming centrifugal pump. With glass casings installed, the internal self-priming mechanism is clearly visible, allowing viewers to have a direct view of the priming process.

Self-priming pumps, unlike regular centrifugal pumps, have the ability to operate even with the presence of air inside the pump, preventing it from becoming air-locked. Instead, the air and water are mixed together at the impeller, the air then separates from the water, which continues to circulate, pulling air out of the suction line, until the pump is primed.

“As the impeller turns here, it creates a vacuum. and pulls the air out of the suction line. What pushes the water into the pump is then the Atmospheric pressure forcing down on the water in the wet well, pushes it into the suction line and into the pump,” said Garry Grant, director of Hydro Innovations.

The combination of clear electronic delivery of information and cutaway views of the internal operation of the pumps is an excellent educational experience. Accompanied by thorough explanations from the Hydro Innovations team, your session at the training centre is assured to be informative.

Hydro Innovations holds regular training and information sessions, and can inform operators and engineers about its full range of products and capabilities. Each session can accommodate up to twelve people.
