The Calpeda GQR 10 Series is a robust range of 415V submersible pumps designed for the efficient drainage of clean water and light wastewater in domestic, commercial, and agricultural applications. Featuring a durable open impeller and vertical discharge, these pumps can handle soft solids up to 10mm, making them perfect for general dewatering, rainwater harvesting, tank emptying, and irrigation.
Each model in the GQR 10 Series includes a double mechanical shaft seal with an oil-filled chamber to protect against dry-running and extend pump life in demanding environments. Designed for continuous duty (S1), these pumps operate reliably under long run times and varied site conditions.
Available in three power/performance variants — GQR 10-12, GQR 10-16, and GQR 10-20 — this series provides flexible solutions for a range of flow and head requirements.
