XH Pump's Self-Priming Pump range offers unparalleled operational flexibility and efficiency for applications where the pump is mounted above the fluid source. Designed and manufactured to the rigorous GB/T5656-2008 standard, this versatile pump category eliminates the need for complex priming systems, enabling quick and reliable start-ups. Our Self-Priming Pump series covers a comprehensive specification range, from small 15mm to large 600mm outlet diameters, handling flows from 1.1 to 8000 m³/h and achieving heads up to 125m. With a suction lift capability of up to 7 meters and the ability to handle media temperatures up to 100°C, it is ideal for water supply, drainage, irrigation, and industrial transfer duties. Crucially, the availability of diverse overcurrent part materials—from cast iron and stainless steels (304, 316L, duplex) to engineered plastics like PP—ensures compatibility with clean water, mildly corrosive liquids, and fluids containing solid particles, providing a robust solution for challenging environments.
