The KP55 is a heavy-duty hydraulic tipper gear pump designed for medium-to-heavy dump trucks. Like the KP35B, it features an all-in-one design that integrates the gear pump, check valve, and control valve into a single cast-iron housing.
High-Flow Output: Delivers 55 mL/r displacement for rapid hydraulic response.
All-in-One Housing: Integrates gear pump, check valve, and control valve together.
Reinforced Cast Iron: Built with heavy-duty material for high structural rigidity.
Precise Proportional Lowering: Allows smooth, controlled lowering of heavy cargo beds.
Universal PTO Mounting: Standard flange design for medium-to-heavy truck transmissions.
| Parameter | Value | Notes |
|---|---|---|
| Displacement | 55 mL/rev | Higher displacement than KP35B, providing greater flow |
| Rated Pressure | 7 MPa (70 kgf/cm²) | Continuous stable operating pressure |
| Maximum Pressure | 17.5 MPa (175 kgf/cm²) | Maximum instantaneous or short-term pressure |
| Rated Speed | 800 rpm | Standard operating speed |
| Maximum Speed | 1,800 rpm | Maximum allowable input speed |
| Rotation | Left-Hand / Counterclockwise (CCW) | Viewed from the pump shaft end; standard configuration |
| Applicable Tonnage | 6–10 Tons | Suitable for medium-duty dump trucks and construction vehicles |
| Control Valve Type | Pneumatic or Cable-Operated Manual Control | Provides lifting, lowering, and neutral/hold functions |
| Valve Body / Spool Material | High-Strength Cast-Iron Valve Body / Alloy-Steel Spool | Impact-resistant and highly wear-resistant |
| Total Weight | Approx. 15.5 kg | Combined weight of the pump and valve; thicker and heavier construction |
Applications
Light & Medium Dump Trucks: Serves as the primary hydraulic power source for lifting 4-to-6-ton tipper truck beds.
Agricultural Equipment: Powers hydraulic dumping trailers, small tractors, and grain handling vehicles.
Municipal Sanitation Vehicles: Drives the tilt-and-dump mechanisms for compact garbage trucks and street sweepers.
Construction Site Dumpers: Applied in mini site dumpers and small-scale material handling lift platforms.
kp55 pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Answer: The primary difference is capacity. The KP55 has a larger displacement (55 mL/r vs 32 mL/r) and is heavier (~15.5 kg vs ~13 kg), designed to lift larger loads of 6-10 tons, compared to the 4-6 ton limit of the KP35B. Their physical mounting dimensions also differ.
Answer: Heavy-duty pumps like the KP55 often experience noise due to cavitation (air trapped in the oil), low hydraulic fluid levels, a clogged suction filter, or misalignment with the PTO shaft. Inspect the oil intake line and fluid levels immediately.
Answer: The standard factory KP55 rotates counter-clockwise (CCW). While some manufacturers offer dual-rotation versions, a standard single-rotation pump cannot be reversed without swapping internal parts (like the side plates and gears) to avoid destroying the internal pressure seals.
Answer: This issue is typically caused by a worn check valve or a scratched spool valve inside the integrated control body, allowing oil to leak back into the reservoir. Inspect the built-in valve seat and replace the internal seal kits if necessary.
Answer: The optimal oil temperature is -20°C to 80°C. For heavy-duty construction use, the hydraulic oil should be changed every 6 to 12 months (or every 500 operating hours), along with cleaning the suction strainer to protect the heavy-duty gears from abrasive dust.
