Introduction to the Performance of ZYB Alloy Gear Pump

ZYB alloy gear pump is a type of gear pump made of high-strength alloy materials, widely used in the industrial field for conveying high-pressure, high viscosity or corrosive media. The following are its main performance characteristics and introduction:

1. Core performance characteristics

Wear resistance

Using high-quality alloy steel (such as CrMo alloy, stainless steel, etc.) to manufacture gears and pump bodies, after heat treatment and precision machining, it has high hardness and strong wear resistance, suitable for transporting media containing particles or high viscosity (such as asphalt, heavy oil, resin, etc.).

corrosion resistance

Optional stainless steel (such as 304, 316) or surface coating treatment, suitable for corrosive liquids (such as acids, alkalis, solvents, etc.) in industries such as chemical and petroleum.

High voltage capability

Compact structural design, high gear meshing accuracy, and pressure bearing capacity of up to 10MPa (some models), suitable for high-pressure system requirements.

Stable flow rate

Precision gear machining ensures minimal flow fluctuations, stable output, and low pulsation rate, making it suitable for flow sensitive scenarios such as precision injection molding and spraying.

Wide temperature adaptability

It can withstand working temperatures ranging from -30 ℃ to 300 ℃ * * (depending on the seal and material), and high-temperature models can choose heat-resistant alloys or gear pumps with added cooling structures.

2. Examples of Technical Parameters

Flow range: 0.5~200 m ³/h (varies according to model and speed)

Pressure range: 0.5~10 MPa

Viscosity range: ≤ 100000 cSt (higher viscosity types can reach even higher)

Speed range: 200~3000 rpm

Caliber range: DN10~DN150

3. Key advantages

Long lifespan: The alloy material and hardening treatment significantly extend the service life and reduce maintenance costs.   

Efficient and energy-saving: The volumetric efficiency can reach over 90%, reducing energy loss.   

Low noise: Optimized gear tooth profile and bearing load, resulting in lower operating noise compared to similar products.   

Multi functional seal: optional mechanical seal, packing seal or magnetic seal, suitable for different media and leakage requirements.   

4. Typical application areas

Petroleum/Chemical: Transportation of crude oil, asphalt, polymers, and corrosive chemicals.   

Metallurgy/Electricity: High temperature lubricating oil, fuel oil, hydraulic oil circulation.   

Food/Pharmaceutical: Sanitary grade stainless steel type is used for high hygiene media such as syrup and liquid medicine.   

Ship/machinery: heavy oil, gearbox lubrication, hydraulic system oil supply.   

5. Selection precautions

Medium characteristics: viscosity, corrosiveness, particle content need to match the material and seal.   

Work pressure/temperature: Select the corresponding pressure level and cooling configuration.   

Installation environment: Special requirements such as explosion-proof and outdoor should be specified in advance. Select the gear pump with the corresponding material.
