KP30.27、 KP30.34 series gear pump

Casappa KP series gear pump:

CASAPPA KP30.27 and KP30.34 series gear pumps belong to its KAPPA 30 series cast iron gear pumps, which are designed for high pressure and high reliability requirements, and are widely used in agricultural machinery, construction machinery, industrial equipment and other fields.：
###1. Core technical parameters
1. **Displacement and pressure**
-**KP30.27**: The theoretical displacement is 26.7 cm3/rev (1.63in3/rev), the maximum continuous working pressure is 280 bar (4060 psi), the system pressure can reach 300 bar (4350 psi), and the peak pressure is 320 bar (4640 psi).
-**KP30.34**: Displacement 34.56 cm3/rev (2.11 in3/rev), maximum continuous pressure 270 bar (3915 psi), system pressure 290 bar (4205 psi), peak 310 bar (4495 psi).
-Both support high-pressure continuous operation and are suitable for heavy-duty working conditions.
2. **Speed and efficiency**
-The maximum speed is 3000 rpm, the volumetric efficiency is more than 95%, and the mechanical efficiency is about 90%, which can achieve high-efficiency energy conversion.
-Built-in shaft end support bearings, which can withstand high radial loads and are suitable for long-term operation.
3. **Structure and materials**
-It adopts a two-body cast iron shell, which has strong impact resistance and is suitable for high temperature and vibration environments.
-Three-dimensional modeling and virtual simulation optimize gear meshing, reduce noise and improve reliability.

###2. Application scenarios
1. **Agricultural machinery**
Such as the hydraulic drive system of tractors and combine harvesters, it supports multi-way valves to control the action of agricultural tools.
2. **Construction machinery**
It includes the drive of the working device of the excavator and loader, and the lifting/turning mechanism of the crane to meet the needs of high pressure and large flow.
3. **Industrial equipment**
It is suitable for the hydraulic power unit of injection molding machines and presses, as well as the precise control of automated production lines.
4. **Mobile machinery**
The steering and braking system of trucks and forklifts, or the hydraulic transmission of ship deck machinery.

###3. Installation and maintenance
1. **Installation configuration**
-Support SAE, DIN, and EUROPEAN standard flanges and shaft extensions to facilitate the integration of existing systems.
-Provide side port or rear port design, optional oil port form (such as NPT, BSPP), high flexibility.
2. **Hydraulic oil requirements**
-It is recommended to use ISO VG 32-68 mineral oil (such as anti-wear hydraulic oil HM), with a viscosity range of 12-100 cSt (60-456 SSU), and PAO synthetic oil is required for low temperature environments.
-The oil temperature range is -20°C to +80°C, and the pressure needs to be limited to below 50 bar during cold start.
3. **Maintenance recommendations**
-**Oil cleaning**: Check the degree of oil pollution every 500 hours, use an ISO 18/15 filter system or above, and recommend the original CASAPPA filter element.
-**Regular maintenance**: Check the status of the seals to avoid leakage; it needs to be re-lubricated and stored if it has not been used for 24 months.
-**Troubleshooting**: Common problems such as abnormal noise may be caused by cavitation or insufficient oil viscosity, it is necessary to adjust the oil inlet line or replace the oil in time.
