Grindex was founded 1940 in Stockholm, Sweden, and started manufacturing of submersible electrical pumps in 1960. Today Grindex has delivered over 350,000 pumps to more than 100 countries. Grindex has representatives in over 50 countries, and operations are quality certified as per ISO 9001 and environmentally certified as per ISO 14001.
For over 50 years Grindex pumps have proven their durable performance in a variety of challenging applications, including Building- and Construction Sites, Mining and Tunneling, Power Plants, Rental, Quarries, Steel Mills, Rescue Operations, different types of Industries and other areas where reliable and highly dependable pumps are required.
Thanks to the built-in motor protection and the air valve, the pumps can run unsupervised for long periods, and even run dry for a length of time.
Grindex submersible Drainage pumps are used for pumping fluids with abrasive particles. They are commonly used for dewatering in applications like mining and construction sites and in quarries. The pumps are equipped with an electronic motor surveillance and air valve that enables dry-running capabilities. The drainage pumps family range from 0.82 kW to 104 kW and have a maximum capacity of pumping up to 330 liters of water per second or lift water up to 230 meter.
Grindex submersible Sludge pumps are used in numerous demanding applications for pumping fluids with solids up to the size of a tennis ball without clogging. The pumps are equipped with an electronic motor surveillance and air valve that enables dry-running capabilities. The sludge pumps family range from 0.9 kW to 6.6 kW and have a maximum capacity up to 28 liters of water per second or lift water up to 40 meters.
Grindex slurry pumps in the Bravo-family are designed for pumping slurry and other fluids with high concentrations of abrasives, like sand and stones. The wear problem is solved by producing hydraulic components in Hard-Iron™, one of the hardest materials available today. Typical applications include dredging, cleaning of settling ponds, coal and ore slurries, Bentonite, coal washing water, sewage treatment plants, steel works, quarries, mines and many other industries. The Bravo pumps family range from 4.7 kW to 78 kW and have a maximum capacity of pumping up to 153 liters of water per second or lift water up to 57 meters.
Grindex Inox range of submersible drainage and sludge pumps are constructed from stainless steel and are intended for use in demanding applications such as mines, process industries, fish farms, harbors and other environment which can quickly destroy conventional pumps. With its impressive allowed pH range, from 2 up to 10, it is hard to find an application that can't be handled by the Inox pumps. All materials in contact with the liquid are made out of AISI 316 stainless steel or better. The Inox pumps family range from 2 kW to 9.7 kW and have a maximum capacity of pumping up to 63 liters of water per second or lift water up to 75 meters.
