Vertical Multistage Booster Set with Schneider ATV Process Drives, from Pump & Valve Specialties.
When the client was looking for a reliable New Zealand locally made and supported multistage booster set, they approached Pump & Valve Specialties to find a solution. With a tight turnaround time of 6 weeks, we reached out to the 43South team who we have previously partnered with on many occasions.
The brief was the vertical multistage pump set needed to have 316 flanged manifolds, and base, to fit in place of the old Grundfos pump system, complete with locally supported pumps and variable frequency drives, CAD drawings and a delivery time of 6 weeks from order. The duty point of the pump set was to handle the varying demands of the prison’s daily water use, as well as the emergency fire system test cycle – this was split over 3 pumps in a duty assist standby configuration.
The manifolds were increased in size to keep the velocity down in the suction and delivery manifolds; this reduced turbulence and vibration in the pump set giving it longer life. The pipework heading to the pump is taken off the top of the suction manifold to remove any chance of air build up in the manifolds. Each pump is also fitted with an air relief valve and thermal cutout to protect the pump units.
The pumps are a stocked item with the motors in the 43South Christchurch production facility – and with the lower lead time and excellent functionality, the Schneider ATV IP55 process drive was the obvious choice.
With serviceability taking top priority, the Schneider drives were mounted on Unistrut with a hinge so they could be folded back when doing routine inspection on the pump units.
From the production facility in Christchurch, they made their way to Wanganui where they were installed on site and commissioned by within the lead time required.
The commissioning and install were under time constrains with limited windows for water to not be available to the site. This was managed very successfully by the team on-site.
It was extremely beneficial with all of the supply partners from 43South, Schneider and Pump & Valve Specialties on-site to go over how the unit works with the operators.
