The Grinder Pump GD-75-50T is a powerful and reliable solution for handling sewage, wastewater, and industrial drainage applications. Built with a high-quality cast iron housing, this pump ensures durability and long-term performance. Featuring a VCT cable with an Epoxy resin base, a dry motor, and dura-mechanical seals, it is designed to withstand harsh environments.
The centrifugal semi-open impeller prevents clogging by effectively grinding materials such as leather, textiles, plastic bags, and rope. With a heavy-duty ball bearing system and IP 68 insulation, the pump operates efficiently while maintaining superior protection. The radial cutter and ring, constructed from SUS-440C material, provide exceptional hardness (HRc 55-60), making it highly effective in breaking down high-tenacity objects.
