ZE high temperature and high pressure petrochemical process pump

ZA and ZE petrochemical pumps are single-stage horizontal centrifugal pumps.

The pump body of the ZA pump is supported by feet, and the pump body of the ZE pump is supported by the center.

Both series of pumps are single-stage radial impellers, which suck in axially and discharge radially.

According to the conditions of use, front and rear wear rings and balance holes are used for hydraulic balance. The shaft seal adopts packing seal, single end face machine seal or double single end face machine seal, and is equipped with cooling, flushing or sealing fluid system.

The standard pipeline is designed according to API610 specification. The pressure levels of the suction and discharge pipe flanges are the same.

From the end of the drive motor, the steering of the pump is clockwise.

 Application

This series of pumps are suitable for transporting various neutral and corrosive liquids (acids, alkalis, salts of various concentrations and temperatures, liquid petrochemical products, organic compounds, etc.).

The temperature range is -80℃450℃, high The use pressure is 2.5Mpa for ZA pump and 5.0Mpa for ZE pump.

This series of products are widely used in oil refineries, petrochemical industry, coal processing industry and cryogenic engineering. Chemical industry, paper and sugar industry and general process industry. Water supply plants, desalination plants, power plants, heating and air conditioning systems, environmental protection projects, ships and offshore industries, etc.

 



 


ZA and ZE petrochemical pumps comply with API610 standards, with a diameter of 25~400mm, a flow rate of 2600m3/h, and a head of 250m.

At the same time, the maintenance conditions required by the process work can be guaranteed. The bearing, shaft seal and impeller are a rotor assembly that can be quickly disassembled or assembled, which greatly shortens the maintenance cycle.

The impeller is a single-suction radial closed type with impeller wear ring and pump body wear ring. After wear, only the wear ring needs to be replaced to reduce maintenance and component costs.

The pump cover is equipped with a cooling and heating bearing box structure. There are two types of shaft seals: packing seal and mechanical seal, users can choose according to different working conditions.

The bearing is lubricated with lubricating oil, and the bearing bracket is equipped with a constant oil ring. The bearing bracket is divided into non-cooling, water cooling, and fan cooling structures. An elastic coupling is used as a connecting element between the pump and the motor, which can compensate for small axial, radial and angular displacements.
