Introduction to the Performance and Advantages of ZYB Gear Pump

ZYB gear pump is a type of positive displacement pump commonly used for conveying high viscosity, high temperature, or granular media, especially in industries such as asphalt, heavy oil, chemical, and food. The following are its performance characteristics

Detailed introduction of advantages:

1、 Performance characteristics of ZYB gear pump

1. Transportation of high viscosity media

Suitable for media with a wide viscosity range (up to hundreds of thousands of cSt), such as asphalt, resin, lubricating oil, etc., with stable and pulsation free transportation.

2. High temperature resistant design

Using high-temperature resistant materials (such as cast steel, stainless steel) and sealed structures, it can transport media with temperatures up to 300 ℃ (depending on the model and configuration).

3. Strong wear resistance

Gears and pump bodies undergo special hardening treatment (such as carburizing, spraying hard alloys), making them suitable for transporting media containing small particles (such as coal tar, residual oil).

4. High voltage output

The working pressure can usually reach 0.6~4.0MPa, and some high-pressure models can be higher to meet the needs of long-distance pipeline transportation.

5. Low speed operation

Adopting a low-speed high torque design to reduce shear force on the medium, suitable for media sensitive to shear (such as food and cosmetic raw materials).

2、 The core advantages of ZYB alloy gear pump

1. Simple structure and easy maintenance

Modular design, easy disassembly; Key components such as gears and shaft sleeves can be quickly replaced to reduce downtime.

2. Strong self-priming ability

Self suction can be achieved without the need for a pump, with a suction range of up to 5 meters (depending on the characteristics of the medium), suitable for intermittent operations.

3. High volumetric efficiency

Precision machined gears have small clearance and minimal leakage, with an efficiency of over 90% and significant energy-saving effects.

4. Bidirectional conveying capacity

By changing the motor direction, the medium can be conveyed in reverse, which is suitable for working conditions that require bidirectional processes.

5. Multiple sealing options

Provide options such as packing seals, mechanical seals (single/double end faces), magnetic seals, etc., to adapt to toxic, flammable, or high-purity media.

6. Wide material compatibility

The pump body material can be selected from cast iron, stainless steel (304/316), corrosion-resistant alloys, etc., to meet the hygiene or anti-corrosion requirements of industries such as food and chemical.

3、 Typical application scenarios

Asphalt industry: High temperature transportation of modified asphalt and emulsified asphalt.

Petrochemical industry: transportation of heavy oil, residual oil, and polymer melts.

Food industry: filling of high viscosity foods such as chocolate and syrup.

Chemical industry: metering and transportation of resins, adhesives, and corrosive media.

4、 Selection precautions

1. Medium characteristics: It is necessary to clarify viscosity, temperature, corrosiveness, and particle content.

2. Flow and pressure requirements: Select the displacement (such as 10-200m ³/h) and pressure level according to the system requirements.

3. Sealing method: For flammable and explosive media, it is recommended to use double end mechanical seals or magnetic seals.

4. Drive configuration: Match motors, reducers, or variable frequency control to adapt to different working conditions.

5、 Advantages compared to ordinary gear pumps

Viscosity adaptability: excellent (up to hundreds of thousands of cSt)

Wear resistance: reinforced treatment, long service life

Sealing options: diversified, high security

Maintenance cost: Low (easy to replace parts)

There are two installation dimensions and parameters for ZYB type: one can refer to KCB type, and the other can refer to 2CY type gear pump.
