The Gorman‑Rupp 80 Series® delivers heavy-duty self-priming performance with a straight‑in suction design that facilitates quick positive priming and higher suction lift than many other pumps. The self-priming pump allows liquid to enter directly into the impeller eye and prevents backflow via an integrated vacuum check valve.
Constructed with a rugged multi-vane open impeller, the pump manages mild solids (up to 48 mm) and provides reliable flow across various industrial applications. The replaceable wearplate helps maintain optimal efficiency while simplifying maintenance and reducing operating costs.
To suit different environments, the 80 Series offers multiple seal configurations (mechanical, grease, oil) and varied drive options including close-coupled, frame-mounted, V-belt, and engine-driven setups – making it a versatile solution for industrial, municipal, agricultural, mining, construction, and petroleum applications.
With a maximum flow up to 3,200 GPM, head up to 210 ft, and ability to handle solids up to 2½″, the 80 Series offers high performance in harsh conditions while maintaining minimal maintenance and long service life.
SK Tech is proud to distribute the genuine Gorman-Rupp 80 Series® pumps in Vietnam, providing full technical support, fast delivery, and professional service.
