ZA type API610 Petrochemical Process Pump, designed and produced according to API610 and VDMA24297 specifications. The ZA type pump body is a foot support. Single suction radial impeller, axial suction, radial exclusion.
According to the conditions of use, the front and rear mouth rings and the balance hole are used for hydraulic balance. The stuffing box has a cooling or heating pipe joint. The shaft seal is sealed with a packing, and a single end or double end mechanical seal can also be used. It is equipped with a cooling, rinsing or sealing fluid system.
Product advantages ● The ZA type chemical process pump is designed with standard piping in accordance with API specifications. The impeller can be closed, half open or open. It can be cleaned, contains particles, and contains a small amount of gaseous medium. It can also transport high temperature, low temperature and strong corrosive media. The impeller is provided with a balance hole and a corrosion-resistant ring to balance the axial force. ● The pump body and the bearing frame are connected by an intermediate connecting section. According to different working conditions, the intermediate connecting section can adopt different materials to avoid serious corrosion of the bearing frame and bearing when conveying strong corrosive medium. At the same time, the intermediate connecting section is provided with a water-cooling chamber, which cools the circulating water, and blocks the high-temperature medium to transfer the high temperature to the bearing. ● The sealing form can be filled with packing, single and double mechanical seals, and assembled single-end mechanical seals. According to different situations and user requirements for cooling and rinsing, the seal can be selected from the case according to API682 design specifications.
● The bearing frame is designed with three types: air-cooled heat sink, air-cooled fan and water-cooled cavity. Users can choose according to the working conditions. The bearing is lubricated by the oil ring from the oil tank. The oil in the oil tank is cooled by the water in the water cooling chamber, and the heat in the bearing is taken away by the cold water to ensure that the bearing is in normal working condition at any time.
It can transport inorganic acids and organic acid solutions such as sulfuric acid, nitric acid, hydrochloric acid and phosphoric acid at various temperatures and concentrations; alkaline solutions such as sodium hydroxide and sodium carbonate at various temperatures and concentrations; various salt solutions; various liquid petrochemicals Products, organic compounds and other corrosive liquids. This type of pump is suitable for refineries, petrochemical industry coal processing engineering, cryogenic engineering, paper industry, sugar industry, water supply plant, desalination plant, power plant, environmental protection engineering and shipbuilding industry. From the motor end, the direction of rotation of the pump rotates clockwise.
