The seawater pump is suitable for: desalination of seawater and transportation of seawater. Features: low speed, corrosion resistant and watertight. Each pump is equipped with a pressure regulating safety valve. The pump pressure can be adjusted arbitrarily and can be equipped with lubricating oil temperature and pressure alarm at the inlet and outlet of the pump. Assembly type: horizontal, vertical, stationary, mobile. Transmission type: electric motor or diesel engine; speed changes include: gearbox, pusher, electromagnetic speed control, speed control with frequency conversion.  - Main components: machine base (pump body made of HT250 material (material: new seawater resistant stainless steel, carbon 316);hardened coating (anti-corrosion layer of nickel-phosphorus alloy) is subjected to heat treatment to avoid fatigue cracking; The kneaded shaft (material: 35CrMo. 42CrMo) is hardened and subjected to solid nitrogen treatment, which ensures high strength, high hardness, wear resistance and durability; plunger (material: superceramic, wear-resistant and corrosion-resistant layer of nickel alloy Ni60, spray-welded (using imported aramid or carbon fiber); Lubrication type: Spray lubrication. Valve groups types: plate valve, flat valve, combined valve. After special treatment, it is wear-resistant and durable.
