ZE Series Chemical Pumps Suitable For Transporting Oil

ZE series chemical pumps suitable for transporting oil

The ZE series process pump is a horizontal, single stage, single suction, radial split volute pump with central support designed in accordance with the American Petroleum Institute API610 8th edition "Centrifugal Pump for Petroleum Heavy Chemical and Natural Gas Industry", API682 "Centrifugal Pump and Rotary Pump Shaft Sealing System" and three national patented technologies, based on the digestion and absorption of advanced pump manufacturing technology from abroad. There are a total of 53 specifications in the entire series, requiring seven types of bearing frame components, with strong universality; The impeller adopts a balance hole and wear-resistant ring to balance axial force, and the pump body with an outlet diameter of over 80mm is designed as a double volute to balance radial force, thereby ensuring the service life of the bearing and the deflection of the shaft at the shaft seal.

This series of pumps has carefully considered the connection between the pump body and bearing frame, mechanical sealing components, cooling methods, and auxiliary pipelines, and solved the usage and installation defects of the process pump and oil pump designed according to API610 7th edition.

The pump body and bearing frame are connected by an intermediate connection section. Depending on different operating conditions, different materials can be used for the intermediate connection section, which solves the problem of bearing frame fracture or severe corrosion when transporting high-pressure, flammable, explosive or highly corrosive media.

The mechanical seal is designed as a containerized structure, and the seal appears as an independent component in the pump. The axial compression is not affected by the axial size of any connecting components, and does not require adjustment, making it easy to install and maintain; According to user needs, non containerized mechanical seals or packing seals can also be equipped; The bearing frame is designed with air-cooled heat sinks and water-cooled chambers, which are located below the oil chamber.

Therefore, when water cooling is required, the bearing frame does not need to be replaced or reprocessed, only a cooling water cover and pipelines need to be added.

The flushing and cooling interfaces on the pump body, pump cover, intermediate bracket, and sealing gland all use tapered pipe threads, which increases the reliability of pipeline sealing.

Application scope and purpose.

Mainly used in refineries, petrochemicals, low-temperature engineering, coal mining, chemical fiber and general industrial processes, power plants, large and medium-sized heating and air conditioning devices, environmental protection engineering, offshore industries, and seawater desalination plants. Convey various clean or small particle containing liquids, low or high temperature liquids, neutral or corrosive liquids.
