Gear pumps are essential components of adhesive machines that require precise, continuous, and reliable delivery of adhesive material. These pumps are used for dispensing and transferring various types of adhesives, including hot melt adhesives, solvent-based adhesives, and reactive adhesives. Let’s explore the features and benefits of gear pumps for adhesive machines.
What is a Gear Pump?
A gear pump is a type of positive displacement pump that uses a set of gears to transfer fluids. The pump consists of two or more gears that mesh together, creating a vacuum that draws in the fluid and moves it through the pump. As the gears rotate, they create a steady flow of fluid without pulsations or surges.
Applications of Gear Pumps in Adhesive Machines.
Gear pumps are used in various adhesive machine applications, including:
- Hot Melt Adhesive Systems: Gear pumps are ideal for hot melt adhesive systems, where the adhesive needs to be maintained at a specific temperature to achieve optimal viscosity. The pumps can handle high viscosities and maintain consistent flow rates, ensuring precise and consistent application.
- Solvent-Based Adhesive Systems: Gear pumps are used in solvent-based adhesive systems, where the adhesive needs to be transferred from one container to another. The pumps can handle a range of viscosities and operate at high pressures, making them ideal for transferring thick and heavy materials.
- Reactive Adhesive Systems: Gear pumps are used in reactive adhesive systems, where the adhesive needs to be precisely metered and mixed before application. The pumps can handle the pressure and viscosity required for the mixing process, ensuring precise and consistent application.
Benefits of Gear Pumps for Adhesives Machines.
Gear pumps offer several benefits for adhesive machines, including:
- Precise and Consistent Flow: Gear pumps offer precise and consistent flow rates, making them ideal for applications that require a specific amount of adhesive to be dispensed. The pump’s design ensures that the adhesive is delivered in a steady stream, reducing the risk of over-application or under-application.
- High-Pressure Capability: Gear pumps can operate at high pressures, making them suitable for transferring viscous and heavy materials. This feature is particularly useful for hot melt adhesive applications, where the adhesive needs to be heated and maintained at a specific temperature to achieve optimal viscosity.
- Compact Size: Gear pumps are compact and require minimal space, making them ideal for adhesive machines that have limited space available. The compact size also makes gear pumps easy to install and maintain.
- Low Maintenance: Gear pumps are simple in design and have few moving parts, making them easy to maintain. The absence of valves and diaphragms means there are no parts that need to be replaced regularly, reducing downtime and maintenance costs.
- Versatility: Gear pumps can handle a wide range of adhesives, including those with high viscosities and varying temperatures. They can also be used for both continuous and intermittent operations, making them versatile for a variety of applications.
The use of poor-quality pumps in adhesive systems can lead to a variety of problems, including:
- Instability of operation: Low-quality pumps can have poor adhesive dispensing accuracy, which can lead to uneven application of the adhesive to the surface. This can cause problems with the quality of the bond and cause deviations in the size and shape of the product.
- Loss of productivity: Poor-quality pumps can run slower or unreliably, which can lead to lost productivity and increased production time. This can also increase the cost of salaries for staff responsible for maintaining the equipment.
- Wear and tear: Poor-quality pumps can wear out more quickly, which can lead to the need for more frequent replacement. This will increase the cost of maintenance and repair of the equipment.
- Risk of accident: Poor-quality pumps may have defects in design or materials, which can lead to equipment failure and danger to personnel.
- Negative impact on product quality: Poor-quality pumps may contain harmful substances that can leach into the adhesive and negatively affect the quality of the product. This can lead to deviations in product quality and negatively influence the company’s reputation.
Therefore, the right choice of pumping equipment for adhesive machines is very important to ensure stable operation of the equipment and high product quality.
Here are our recommendations that will help to choose the right option:
- Determine the pump requirements: Before choosing a pump, it is necessary to determine what adhesives will be used, their consistency, temperature. and viscosity. These parameters will help to choose the pump that will work most efficiently with the selected adhesive.
- Select the type of pump: There are many types of pumps available, but for gluing machines, specifically gear pumps are commonly used, but they differ in types, modifications, and performance. At this stage, a sales specialist will help to clarify all the moments and resolve the issue.
- Select pump material: The pump material must be suitable for the adhesive to be used. For example, for solvent-based adhesives, pumps made of a material that does not react with solvents should be used.
- Check the pump’s performance: Before selecting a pump, check its performance. The pump must be capable of handling the required volume of adhesive in the allotted time to ensure the efficient operation of the machine.
- Check the reliability of the pump: The pump must be reliable and resistant to wear and tear. It must be able to withstand the high temperatures and pressures that can be encountered when handling adhesives.
