Description

Key Features of the CASAPPA KP30 Gear Pump

1. Compact and Robust Design

  • High Power Density: The pump is designed to deliver significant flow and pressure relative to its small size and weight. This makes it ideal for applications where space is limited, such as in compact machinery.

  • Durable Construction: Typically built with a cast iron body, which provides excellent resistance to wear and tear and ensures a long operational life, even in demanding environments.

2. High Operating Pressure

  • The KP30 is designed to operate continuously at high pressures. A common specification for this series is:

    • Maximum Operating Pressure: Up to 250 bar (≈ 3625 psi)

    • Peak Pressure: Up to 280 bar (≈ 4060 psi) for short durations.

    • This high-pressure capability allows it to drive powerful actuators like hydraulic cylinders and motors.

3. Wide Speed Range

  • The pump can operate efficiently across a broad range of rotational speeds.

    • Minimum Speed: Can run at very low speeds (e.g., 600 rpm) for precise control.

    • Maximum Speed: Can handle high speeds (e.g., 3000 rpm and beyond, depending on the model variant), making it versatile for different prime movers like electric motors or internal combustion engines.

4. High Volumetric and Overall Efficiency

  • Precision Machined Gears: The gears and internal components are manufactured to very tight tolerances. This minimizes internal leakage (slip) and maximizes volumetric efficiency, meaning it delivers a high percentage of its theoretical flow output.

  • Optimized Bearing and Gear Design: Reduces mechanical friction, leading to high overall (hydromechanical) efficiency. This translates to less power lost as heat and lower fuel or energy consumption for the driving engine/motor.

5. Low Noise Level

  • CASAPPA places a strong emphasis on noise reduction. The KP30 features:

    • Precision Ground Gears: Results in smooth and quiet meshing of the gear teeth.

    • Optimized Porting: The design of the inlet and outlet ports helps to minimize flow ripples and pressure pulsations, which are major contributors to hydraulic noise.

6. Shaft and Sealing Options

  • Shaft Options: Available with various shaft types (e.g., parallel key, splined) to suit different coupling and connection requirements.

  • Shaft Seal Options: Offered with standard lip seals or highly durable Viton® seals for applications involving extreme temperatures or compatibility with certain hydraulic fluids.

  • Rotation: Available in both clockwise and counter-clockwise rotation versions.

7. Porting and Mounting Flexibility

  • Standard Porting: Typically comes with SAE flanged ports (e.g., 2-bolt SAE A or 4-bolt SAE B), which are industry standards for easy integration into hydraulic systems.

  • Mounting: Features a standard SAE mounting flange (e.g., SAE A or B 2-bolt), allowing for easy and direct mounting to reservoirs, valves, or other pumps in a circuit.

8. Multiple Displacement Sizes

  • The "KP30" designation often refers to a frame size. Within this frame, the pump is available in a range of displacements (volume of fluid delivered per revolution). Common displacements for this size are around 30 cm³/rev (1.83 in³/rev), but other sizes may be available (e.g., 28, 32, 36 cm³/rev). This allows users to select the exact flow rate needed for their application.

9. Multi-Pump Configuration (Tandem Pumps)

  • One of the most powerful features is the ability to create a tandem pump configuration. The KP30 can be coupled with additional gear pumps (e.g., another KP30, a smaller KP10, or a larger KP50) or even a CASAPPA gear motor to form a single, compact unit.

  • Benefit: This allows a single engine or motor to power multiple independent hydraulic circuits (e.g., for steering, lifting, and tool functions), simplifying design and saving space.

10. Broad Fluid Compatibility

  • Designed to work effectively with a wide range of hydraulic fluids, including:

    • Mineral-based hydraulic oils

    • Biodegradable fluids (like HETG/HEES)

    • Synthetic fluids

    • Water-glycol fluids (specific seal kits may be required for non-mineral oils)
