12 Inch Discharge Single-Stage Single-Suction Horizontal High Head Pump
Product Introduction
The pump is innovative in hydraulic design and structural design. The over-current components are cast with anti-abrasion high-chromium wear-resistant alloy. It is characterized by high efficiency, energy saving, wear resistance and reliable operation. It is suitable for conveying strong abrasive mortar containing solid particles. Mortar, slag, etc., the solid-liquid mixing concentration can reach 60%. It is an ideal sand-drawing and sand-feeding equipment. Users can use long-distance construction by single or multi-machine series operation according to actual working conditions. Widely used for sand pumping, iron extraction, gold sand, sea reclamation, electric fly ash transportation, metallurgical industry, tailings, etc. The maximum mixing flow can reach 5000 cubic meters / hour, the maximum depth can reach 30 meters, suitable for various needs Large-flow, deep-water pumping sand extraction environment.
Application fields
1. Draining sand from rivers, lakes, seas and reservoirs, reclaiming land from the sea, extracting iron ore, and scouring sand.
2. It is suitable for extracting a variety of yellow sand, mineral sand, industrial and mining enterprises to transport tailings slurry, tailing sand mine, slurry, slag, electric fly ash transport and other strong abrasive media.
3. It is widely used in pebble and large particles, and has a large environment for pump over-current capability: river, lake, sea, reservoir, sand pumping, large particles, river dredging, high lift and other construction environments, suitable for dredging Mud, shale, pebbles, mining and metal smelting waste transportation.
