2. How the Gear Pump Works

The OTS-50 Gear Pump is a positive displacement pump that uses the meshing of gears to move fluid. It operates by trapping fluid in the spaces between rotating gears and the pump casing, then displacing it from the inlet to the outlet as the gears turn. The precise movement of the gears allows for controlled, consistent fluid flow, making gear pumps ideal for handling both low and high-viscosity fluids in a wide range of industrial applications.

Operating Principle:

Fluid Inlet:
- As the pumps gears rotate, they create a vacuum at the inlet, drawing fluid into the pump. The suction force is created by the separation of the gear teeth as they rotate away from each other.
Fluid Transfer:
- Once the fluid is drawn into the pump, it becomes trapped in the pockets between the gear teeth and the pump casing. As the gears continue to rotate, these pockets carry the fluid around the outer edge of the pump chamber.
Pressure Generation:
- As the gears rotate toward the discharge side, the teeth come back together, forcing the fluid out of the pump and into the connected piping or spray system. This pressure generation is essential for delivering the precise amount of fluid needed in high-pressure applications such as electrostatic spray systems.
Control Through Gearbox:
- Each OTS-50 Gear Pump is equipped with a 7:1 gearbox. This gearbox reduces the motor speed while increasing the torque, allowing the pump to handle high-viscosity fluids and deliver consistent flow even in challenging environments.
- By slowing the rotation of the gears, the gearbox ensures more efficient handling of fluids with varying viscosities while maintaining a steady output pressure, perfect for applications like automotive coatings or heavy-duty industrial paints.

Why Gear Pumps Are Ideal for Industrial Coatings:

High-Precision Delivery: The positive displacement mechanism ensures a steady, precise flow rate, which is crucial for uniform paint application.
Versatility: The OTS-50 series is designed to handle a variety of fluid viscosities, from thin liquids to thick coatings, without sacrificing performance.
Pressure Management: With the ability to handle pressures of up to 200 bar, the OTS-50 gear pump is ideal for high-pressure systems that demand reliability and consistency.
Durability: Thanks to the hardened materials and precise engineering, our gear pumps are resistant to wear, ensuring a long operational life even in abrasive or corrosive fluid environments.

Common Causes of Gear Pump Wear:

Over time, the gears in any pump experience wear due to the abrasive nature of industrial fluids, including paints and coatings. As the gears wear down:

Gaps between gear teeth widen.
The pumps suction ability decreases.
Fluid leakage may occur between the gear teeth, leading to reduced flow rates and lower efficiency.

Replacing worn gear pumps before severe performance degradation occurs can help prevent system downtime, reduce paint waste, and maintain optimal production rates.

Technical Specifications Table

The following table provides a comprehensive overview of the OTS-50 Gear Pump Line models, including key performance metrics, dimensions, and applications. This detailed information allows customers to compare different models and choose the one that best fits their fluid transfer and coating needs.

Flow Rate vs Viscosity (with 7:1 Gearbox):
This chart illustrates the effect of increasing viscosity on the flow rate for both pump models. As viscosity increases, flow rates decrease, with the 6cc/rev pump maintaining a higher flow rate compared to the 3cc/rev pump.

Pressure vs Flow Rate (with 7:1 Gearbox):
This chart demonstrates how increasing pressure reduces the flow rate for both pump models at 1000 RPM and 2000 RPM motor speeds. The 6cc/rev pump shows a higher flow rate at both motor speeds compared to the 3cc/rev pump.

Flow Rate vs Motor Speed (RPM) (with 7:1 Gearbox):
This chart shows how the flow rate increases with motor speed for both the 3cc/rev and 6cc/rev pumps, taking into account the 7:1 gearbox ratio. The 6cc/rev pump provides a higher flow rate compared to the 3cc/rev pump.

Explanation of Key Metrics :

Displacement (cc/rev): The volume of fluid moved by the pump for each revolution of the gears. Higher displacement values indicate a larger volume of fluid is being pumped per revolution, suitable for applications requiring higher flow rates.
Max Pressure (bar): The maximum operating pressure the pump can handle. This is particularly important for high-pressure applications like electrostatic spray systems, where maintaining consistent pressure is critical for proper fluid atomization and application.
Motor Power (HP): The power output of the pump’s motor, measured in horsepower (HP). This metric reflects the energy the motor can deliver to ensure the pump operates effectively, especially when handling higher viscosity fluids or operating at higher pressures.
Torque (Nm): The rotational force generated by the motor and gearbox combination, expressed in Newton-meters (Nm). Higher torque values are essential for pumping thicker fluids or handling high-resistance applications, ensuring the pump delivers the necessary force for fluid movement.
Gearbox Ratio: This indicates the gear reduction used to slow the motor’s speed while increasing torque. The 7:1 ratio means that for every seven turns of the motor, the gears rotate once, ensuring higher torque output, which is ideal for pumping high-viscosity or abrasive fluids.
ATEX Certification: Indicates whether the pump is certified for use in explosive or hazardous environments. ATEX certification ensures that the pump can safely operate in zones where flammable substances are present, such as chemical plants or paint manufacturing facilities.
Max Temperature (°C): The highest temperature at which the pump can safely operate. This is particularly relevant for applications dealing with high-temperature coatings or fluids that need to be maintained at elevated temperatures during application.
Viscosity Range (cP): The range of fluid viscosities the pump can handle, measured in centipoise (cP). A broader viscosity range allows the pump to handle a variety of fluids, from thin waterborne paints to thick, high-viscosity coatings.
Material: The construction material of the pump’s components. OTSON offers pumps made from carbon steel, stainless steel, and hardened alloys to ensure durability and longevity, particularly when handling corrosive or abrasive fluids.
Weight (kg): The total weight of the pump, which may impact installation and handling requirements in specific applications.
Dimensions (L x W x H) (mm): The physical size of the pump, providing an indication of the space required for installation. Smaller pumps are typically easier to integrate into compact systems, while larger pumps may offer higher capacity and pressure ratings.
Flow Rate (cc/min) (with Gearbox): The volume of fluid the pump can move per minute, depending on its displacement and the motor’s speed. This flow rate helps determine the pump’s suitability for specific coating applications, ensuring it can meet production requirements.
Transfer Distance (m): The maximum distance the pump can transfer fluid before a significant drop in pressure or flow rate occurs. This is especially important in large production facilities where fluids need to be transported over long distances.

Choosing the Right Pump for Your Application:

The technical specifications of each model in the OTS-50 Gear Pump Line are designed to meet the varied needs of different industries. Whether you require high pressure for electrostatic spray systems, the ability to pump highly viscous or abrasive fluids, or ATEX-certified models for explosive environments, the OTS-50 series offers the flexibility and reliability needed to optimize your fluid transfer processes.
