Introduction:

The ZA and ZE petrochemical pumps are widely used in the petroleum, chemical, and other industries. These pumps have a variety of unique features and can be classified into several categories based on their design and applications.

Classification

The ZA and ZE petrochemical pumps can be classified into the following categories:

Single-stage centrifugal pump

These pumps are designed to handle a wide range of fluids with varying viscosities, pressures, and temperatures. They have a simple design and are easy to install and maintain.

Multi-stage centrifugal pump

These pumps are used for high-pressure applications and can handle fluids with low viscosity. They have multiple impellers and diffusers that increase the pressure and flow rate of the fluid.

Self-priming centrifugal pump

These pumps are designed to handle fluids with high viscosity and can operate in areas where the suction head is low. They have a unique design that allows them to prime automatically without the need for external assistance.

Horizontal or vertical pump

These pumps can be mounted in a horizontal or vertical position, depending on the application. Vertical pumps are ideal for applications where space is limited, while horizontal pumps are used for applications where high flow rates are required.

Features

The ZA and ZE petrochemical pumps have several unique features, including:

Corrosion-resistant materials

These pumps are made of materials that are resistant to corrosion and can withstand aggressive chemicals and fluids. They are also designed to prevent leaks and spills.

High efficiency

These pumps are designed to be highly efficient and can operate at high flow rates with low energy consumption. They are ideal for applications where energy efficiency is a critical factor.

Easy maintenance

These pumps have a simple design that makes them easy to install and maintain. They also have replaceable parts that can be easily accessed and replaced, reducing downtime and maintenance costs.

Wide range of applications

These pumps can be used in a variety of applications, including chemical processing, oil and gas production, and water treatment.

Conclusion:

The ZA and ZE petrochemical pumps are versatile and reliable pumps that are widely used in the petrochemical and chemical industries. They have a variety of unique features and can be classified into several categories based on their design and applications. These pumps are an excellent choice for applications where high efficiency, easy maintenance, and corrosion resistance are critical factors.

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℃, thehigh 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, chemicalengineering. Chemical industry, paper and sugar industry and general process industry, waterindustry. 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, havingwith 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 wearing,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. ElasticAn elastic coupling is used as a connecting element between the pump and the motor, which can compensate for small axial, radial and angular displacements.
