The Grinder Pump GD-50-50T is a powerful and efficient sewage pump designed for handling tough wastewater applications. Built with a high-quality cast iron housing, it ensures durability and long-term use. Featuring a robust VCT cable with an epoxy resin base, dry motor, and dura-mechanical seals, this pump delivers exceptional performance in demanding environments.

Equipped with a centrifugal semi-open impeller, it effectively prevents clogging by grinding down high-tenacity materials like leather, textiles, plastic bags, and rope. The radial cutter and ring, made from hardened SUS-440C material (HRc 55-60), enhance cutting efficiency and reliability. With an IP 68 insulation level, heavy-duty ball bearings, and built-in motor protection, the GD-50-50T is engineered for maximum performance and longevity.
