Sollentuna, Sweden -- With the launch of its latest Micro, Mini, and Solid pumps, Swedish company Grindex says it is "setting new standards in the small pump market." The pumps, which can handle 4, 6, and 7 l/s of material and pump up to 10, 16 and 12 metres respectively, are the latest Grindex pumps to go through a complete revamp.
All the pumps are designed to be lightweight, robust and durable, making them ideal for use in harsh environments. Features for improved operation include an air valve that cools the motor when the pump runs dry; a water cut-out that prevents leakage through the power cable; a thermal contact that protects the motor from overheating; double mechanical shaft seals in the oil bath, essential for a long lifespan in tough applications; and a rubber strainer that improves the shock resistance.
Grindex says ease of serviceability has also been an important focus in the redesign. The new Mini and Solid pumps, for example, have external oil plugs meaning that they do not need to be disassembled to check the oil, this can be done quickly and easily on site.
"Evolving the pumps is an important part of our business at Grindex," said Hakan Lundin, group sales manager, in a company statement. "One of the reasons we have been so successful over the years is that we always make ourselves available to our customers and we listen to their needs. Much of the pump revamp process is in response to what they have been telling us."
The Solid sludge pump comes with a polyurethane impeller and pump housing that provides high wear resistance when pumping abrasive media, making the pump even more hard-wearing. This is particular important as such pump are often running in water containing relatively abrasive solids, in fact it can handle solids up to the size of 38 mm.
