Orion KRF series Vacuum pump

The Orion KRF series encompasses oil-free, dry rotary vane vacuum pumps known for their reliability, durability, and quiet operation. These pumps are a popular alternative to traditional oil-sealed rotary vane pumps across various industrial applications.

Here’s a general overview of the Orion KRF vacuum pump:

Key Features:

• Oil-Free Operation: Eliminates the need for oil lubrication, resulting in cleaner operation, reduced maintenance, and no risk of oil contamination in the process.
• Maintenance-Free Design: Designed for minimal upkeep, contributing to reduced downtime and operational costs.
• Quiet Operation: Engineered to operate with low noise levels, creating a more comfortable working environment. Noise levels typically range from 60 to 70 dB(A) depending on the model.
• Cooler Running Outboard Bearings: This design enhances the service life of the pump by reducing heat generation and wear on the bearings.
• Built-in Particulate Filters and Silencers: Protects the pump from dust and debris, ensuring reliable performance and further reducing noise.
• Compact and Lightweight Design: Facilitates easy installation and integration into various systems.
• Versatile Applications: Capable of handling both vacuum and pressure applications, making them suitable for a wide range of uses.
• Longer Life Carbon Vane Design: Utilizes specially designed carbon vanes that offer extended operational life compared to standard vanes.
• CE Certified (on some models): Indicates compliance with European safety standards.

Operating Principle:

Orion dry pumps, including the KRF series, operate on the rotary vane principle. An eccentrically mounted rotor with sliding vanes rotates within a housing. As the rotor turns, the volume between the vanes and the housing walls changes. This cyclical change in volume creates a vacuum at the inlet (suction phase) and compresses the air, which is then expelled through the outlet (discharge phase).

Typical Applications:

Orion KRF vacuum pumps are used in a diverse range of industries and applications, including:

• Packaging Machines: Vacuum packaging to extend shelf life.
• Printing and Binding Machines: Paper handling and feeding.
• Photographic Processing: Film and print handling.
• Insertion Machinery: Component placement in automated assembly.
• Vacuum Lifting and Chucking: Material handling and securing parts.
• Robotic Arms: End-of-arm tooling for pick-and-place operations.
• Vacuum Forming: Shaping plastic materials.
• Computer Applications: Cooling and other vacuum-related processes.
• Paper Counting and Labeling Machines: Material handling.
• Parts Feeders: Orienting and feeding components in automated systems.
• Dust and Gas Sampling: Environmental monitoring.
• Vacuum Tweezers/Pickups: Handling small components.
• Air Bearings: Providing frictionless support.
• Oxygen Production: Medical and industrial applications.
• Medical Equipment: Various applications requiring vacuum or pressure.
• Woodworking (CNC machines): Securing workpieces.
• Plastics Manufacturing (injection molding): Degassing.
• Semiconductor and Electronics Industries: Various handling and processing applications.

Model Variations and Specifications:

The KRF series includes different models with varying specifications to suit specific application requirements. Key specifications to consider include:

• Pumping Capacity (Flow Rate): Measured in liters per minute (L/min) or cubic meters per hour (m³/h), indicating the volume of air the pump can move. Different models offer flow rates ranging from approximately 75 L/min to 2200 L/min (at 60 Hz).
• Ultimate Vacuum: The lowest pressure the pump can achieve, typically expressed in kPa (kilopascals) absolute. KRF series pumps can reach ultimate vacuum levels down to 84-90 kPa (relative to atmospheric pressure).
• Continuous Operating Vacuum: The recommended and maximum continuous vacuum levels for stable operation, typically around 60-80 kPa.
• Continuous Operating Pressure: For models capable of pressure operation, this indicates the maximum continuous pressure the pump can handle, typically around 60-70 kPa.
• Motor Power: Varies depending on the model and required performance, ranging from 0.1 kW to 3.7 kW. Single-phase and three-phase motor options are available with different voltage ratings (e.g., 100/220V, 200V, 220/380V, etc.) and frequencies (50/60 Hz).
• Piping Connection Size: The port size for inlet and outlet connections, typically specified as Rc (tapered pipe thread).
• Weight: Varies depending on the model.

In summary, the Orion KRF vacuum pump is a reliable, oil-free solution offering quiet operation, low maintenance, and versatility for a wide array of industrial vacuum and pressure applications. When selecting a specific KRF model, it’s crucial to consider the required flow rate, vacuum/pressure levels, and electrical specifications for your intended use
