Project Background

The asset owner at the Mount Piper Power Station (Mr. Rainer Scheurer) was looking for a solution to the maintenance issues associated with his submersible pump stations on the site. The problems were many and varied, including lifting chains breaking, sewage pumps becoming stuck on their guide rails, as well as general reliability issues. Even with everything going well, operators would be exposed to a 7m fall into the pit whilst hoisting submersible pumps to the surface for maintenance.

Mr Scheurer came to Hydro Innovations for some ideas on how he could get away from these issues. Hydro Innovations suggested the use of Gorman-Rupp self-priming pumps, which would mean that only one operator would be needed for most of the maintenance issues, and any work could be done without opening wet well covers. Rainer liked the idea, but the pit was so deep, that self-priming pumps could not be located at ground level.

The operators were happy with the pumps and how easily they can now be accessed for monitoring and maintenance

The Options

Hydro Innovations suggested putting the pumps into the existing valve vault (to get pumps closer to water level), re-using the path the old discharge lines took, and connecting directly into the existing rising main in the valve vault.

Gorman-Rupp’s V3B60-B pumps were chosen for the job, to deliver the 15 litres per second flow rate, but most importantly, were capable of re-priming the required 7.6 metre suction lift – a tough ask for most self-priming pumps. Hydro Innovations explained that most self-priming pumps with a full casing of liquid are capable of priming to this level, but re-priming automatically, with only a partially filled casing (because casing siphoning can occur between pump cycles) is a totally different proposition. As Gorman-Rupp publish guaranteed re-prime lifts on their pump curves, Hydro Innovations had no hesitation applying the pump on this suction lift.

The Solution

Hydro Innovations were duly given the go-ahead on the pump stn project and set to work designing a piping and valve system that could comfortably fit in the valve vault. A compact but practical design was approved and the project delivered.

Mount Piper Power Station now has a pump stn that is undercover (inside the valve vault), is easily accessed without the need for lifting apparatus, and can be safely maintained by one operator.
