KP30.27 Casappa Kappa 30 Gear Pump 26.7cm³ 280bar

Product Overview

The KP30.24, KP30.27, KP30.29 and KP30.30 models belong to the Casappa Kappa 30 series of external gear pumps. Designed for medium-to-high pressure hydraulic systems, these pumps feature high-strength cast iron housings and precision-machined gears. They offer excellent interchangeability for direct OEM replacement of original Casappa units and equivalent brands. Every unit undergoes 100% simulated duty-cycle testing to guarantee volumetric efficiency, pressure stability and service life matching factory standards. Ideal for truck PTO applications, mobile machinery and industrial hydraulic circuits.

Key Technical Advantages

1. Precision machining and high-strength cast iron construction: Surface-hardened and ground gears with optimized tooth profile and controlled clearances deliver high volumetric efficiency and low pressure losses under continuous medium-to-high pressure duty.
2. High volumetric efficiency with low-noise design: Optimized internal flow paths and bearing support reduce operating noise and vibration, improving overall system comfort and efficiency.
3. Long-life bearings and thrust plate options: Quality plain bearings and optional bronze thrust plates provide strong contamination resistance and extended service life, reducing maintenance intervals.
4. Excellent interchangeability and modular design: Flanges, shaft ends and ports fully match original Casappa Kappa 30 units. Supports single, tandem and multiple pump configurations for easy drop-in replacement and system upgrades.
5. 100% simulated duty-cycle testing: Every pump is pressure-, flow- and speed-tested under real operating conditions to ensure consistent performance and high reliability.

Application Areas

• Truck and commercial vehicle PTO-driven hydraulic systems
• Construction machinery (loaders, excavator auxiliary circuits, cranes)
• Agricultural and forestry equipment
• Industrial hydraulic power units, presses and injection moulding auxiliaries
• Material handling and port machinery

Expert Maintenance Tips

1. Verify rotation direction before installation (S = counterclockwise when viewed from shaft end). Fully prime the suction line and purge air to avoid dry running.
2. Use hydraulic fluid meeting ISO 4406 19/17/14 cleanliness or better. Change filters regularly to prevent premature gear and bearing wear.
3. Tighten shaft-end nut to approximately 70 Nm (confirm for specific shaft type) to avoid seal failure from over- or under-tightening.
4. After start-up, check for leakage and abnormal noise. Keep continuous operating temperature between -25 °C and 80 °C (peak ≤ 100 °C). Select special shaft seals for high back-pressure applications.
5. For long-term storage, run briefly under light load and replace with fresh fluid to prevent internal corrosion.
