Stockholm – At this year's BAUMA exhibition, Grindex announced the launch of its updated range of drainage and sludge pumps. The updated pumps deliver increased running time and require less maintenance, which in turn reduces the total cost of ownership.
As part of the continued strategy to provide customers with submersible electrical pumps that deliver the most value for money throughout their lifecycle, the Swedish pump manufacturer Grindex has launched its next generation of drainage and sludge pumps. The Minex, Minette, Minor, Major, Master and Matador drainage pumps and the Salvador, Senior and Sandy sludge pumps have all been updated to deliver improved pumping performance, while the need for maintenance and spare parts has been reduced.
The updated pumps now have a new seal design with a robust metal housing that offers improved heat transfer and sealing function for a longer life.
The pumps now consist of fewer parts, which reduce the risk of leakage and speeds up the maintenance process. A new lifting handle and a deeper groove in the strainer also means they are more ergonomic, while the Minor, Major, Senior and Sandy have new lifting eyelets for hooks. Also the dry running performance has been improved thanks to more and better air valves, and larger oil volume.
Improved hard-wearing features include new wear resistant impellers for the Minex and Minette drainage pumps, a wear resistant coating of polyurethane for all sludge pumps and a polyurethane option for Minor to Matador drainage pumps.
A further safeguard measure is the proven SMART motor protection, which cuts the power if the temperature gets too high or if it loses a phase. The SMART also ensures the impeller turns in the right direction.
"At Grindex we are continuously working to develop our solutions, whether that means changing a screw to simplify maintenance, or opting for a new casing for greater durability and overall performance," says Technical Engineer, Jonas Bladh. "Many of the changes in this latest generation of pumps are based on conversations with our customers and field engineers. We've listened to what they have to say, and where an improvement could be made we've made it," he concludes.
