There is safety regulating valve in every type of such pump. Pressure can be regulated freely. Oil temperature and pressure are protected automatically. Assembly type: horizontal or vertical. Transition type: electric motor or diesel; There are 4 ways of speed regulation,ie: by gear box, belt wheel, electromagnetic or frequency-changing. Main parts: Machine seat (material used: HT250) Pump body (material used: 316, 1Cr18Ni9Ti, 2Cr13, Nickel-phosphorus alloy galvanized carbon steel layer) Heat treatment is applied to prevent fatigue crack. Crank shift (material used: 35CrMo, 42CrMo) Nitrogen hardening treatment is applied to attain strong strength, high hardness, durable and corrosion resistant feature. Plunger (material used: superior ceramic, Ni60 alloy nickel-coated wear resistant and anti-corrosive layer). Packing seal Imported imitating polyamide fiber（aramid fiber） or carbon constructional fiber are used. Splashing form of lubrication is used. Valve types: conical valve, plate valve, ARN valve and combined valves. They are wear resistant and anti-corrosive after special treatment. Every pump is equipped with safety regulating valve. Pressure of pump can be regulated freely. Alarm protection for temperature of lubricating oil and inlet and out pressure of the pump are equipped.
