Midwest Piggery
Midwest Piggery are very happy with Gorman-Rupp wastewater pump as it reduces costs and is extremely easy to maintain.
Project Background
Midwest Piggery has been breeding pigs for over 30 years. A mid-size enterprise, the piggery raises the animals and then sells them to market. As part of the piggery’s recycling philosophy, all pig waste is collected and broken down before being used as fertiliser on the grounds.
‘We collect the pig waste in what we call sump pits,’ explained Mat Collier, Principal Partner and Manager of Midwest Piggery.
‘The effluent is then pumped from the sump up to a holding dam. It then moves progressively through a series of dams before the effluent is eventually ready for use as a fertiliser. After we bought the helical rotor pumps we quickly discovered that they have a very fine tolerance. The suction hose started to block continuously and if the pumps ran dry, the motor would burn out and the rubber stator melted. Not only did we have to remove the choke, we had to replace the stator which was incredibly awkward and frustrating. Getting to the stator is difficult enough, and then we had to literally peel away the melted rubber which had stuck to the equipment. Every time we had to clear the choke and replace the stator it took a good 3-4 hours of our precious time,’ said Mat.
‘It’s great to see that there are still suppliers out there who will stand behind their products and let you trial them before buying. If Hydro Innovations hadn’t let me trial the pump I doubt I would have bought it upfront because I have been burnt so many times before. After all my negative experiences, the Gorman-Rupp T2A3-B self priming pump is far more than I hoped for,’ said Mat.
The Options
The process not only proved time intensive, it was also very costly. According to Mat, a new stator costs about $1,000 and because the sewage pumps were choking and burning out with increasing regularity the cost to replace the stator was also growing. In one year alone, the piggery had spent about $10,000 on new stators. Fed up and frustrated with the helical pumps, Mat started to search for a far more efficient solution. Coincidentally, Mat’s father-in-law had just read an article on Hydro Innovations and the Gorman-Rupp pumps that they supply and drew Mat’s attention to it. After reading it, what particularly appealed to Mat was the fact that Hydro Innovations was happy to provide prospective customers with a trial period.
‘Having paid and used a series of pumps including submersible pumps in the past, I didn’t want to spend any more money on pumps that could not do the job. So coming across a supplier who was happy to let the pump prove itself before I bought it was great,’ said Mat.
After reviewing the piggery’s requirements, Hydro Innovations suggested that Mat install a Gorman-Rupp T2A3-B wastewater pump fitted with a 4kW motor – a compact model that would provide both the flow and the pressure that Mat needed.
According to Garry Grant, General Manager of Hydro Innovations, the Gorman-Rupp T2A3-B is a rugged, self-priming, solids-handling centrifugal pump. Very easy to maintain, the pump has an external removable flap valve that can be removed and inspected without the inconvenience of disconnecting the piping or draining the pump casing. In addition, if any choking does occur, the centrifugal pump can be easily and quickly unclogged via the removable cover plate.
The Solution
Garry was more than happy to have Mat trial the centrifugal pump for 90 days, but within 60 days Mat was convinced that the Gorman-Rupp T2A3-B self-priming pump could effectively do the job and purchased the pump.
‘Within two months of having the self-priming pump installed at the piggery, I knew that it was capable. It moves more liquid than the previous pump and it’s extremely easy to maintain which for me is the major bonus. The open impeller design makes it very simple to remove any blockages. I only have to loosen two bolts to get inside the pump and clear it which takes me just 15 minutes,’ said Mat.
‘And of course, an added bonus is that we no longer have to waste money purchasing stators,’ he said. So impressed was Mat with the performance of the Gorman-Rupp T2A3-B that he purchased a second centrifugal pump and is now considering a third pump.
‘It’s great to see that there are still suppliers out there who will stand behind their products and let you trial them before buying. If Hydro Innovations hadn’t let me trial the pump I doubt I would have bought it upfront because I have been burnt so many times before. After all my negative experiences, the Gorman-Rupp T2A3-B self-priming pump is far more than I hoped for,’ said Mat.
