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.
KPG140 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.
Internal Wear: Severe wear on the internal thrust plates (floating side plates) or gear faces increases internal clearance, causing high internal leakage.
Relief Valve Issue: The system's main relief valve might be stuck open, diverting all pressurized oil straight back to the reservoir.
Suction Blockage: A clogged suction filter or a collapsed inlet hose restricts oil flow, preventing the pump from drawing enough fluid.
Cavitation: Air leaking into the suction line, a restricted inlet, or fluid that is too thick creates vapor bubbles that collapse violently inside the pump.
Misalignment: Poor concentricity between the pump shaft and the driving motor/engine shaft causes mechanical vibration and premature bearing failure.
Gear Damage: Contaminants in the hydraulic oil can scratch the gear teeth, chip the edges, or cause uneven gear mesh.
Check the Shaft End: Face the drive shaft end of the pump directly. If it needs to turn clockwise, it is CW; counter-clockwise is CCW.
Never Run Backwards: Operating a gear pump in the wrong direction will instantly blow out the shaft oil seal due to misplaced internal pressures.
Identify Ports: On high-pressure gear pumps, the larger port is always the inlet (suction), and the smaller port is the outlet (pressure).
High Internal Case Pressure: The internal drain passage could be blocked by debris, building up excessive pressure behind the seal lip.
Shaft Grooving: The shaft surface where the seal sits may be worn down or grooved. Replacing just the rubber seal will not fix a damaged shaft.
Radial Loading: The pump shaft might be taking a side load from a misaligned coupling, causing the seal to wear unevenly on one side.
Full Model Code: "KPG140" usually just specifies the displacement/series. You must check the full nameplate for specific flange, shaft, and port modifications.
Measure 3 Key Metrics:
Mounting Flange: Pilot diameter (e.g., SAE-B or SAE-C standard) and bolt hole spacing.
Drive Shaft: The number of splines and outer diameter, or the keyway width for straight shafts.
Port Style: Verify if it uses split flange connections (SAE 4-bolt) or standard threaded ports (G or NPT).
