Hand Pallet Truck Hydraulic Pump Core

1. Product Overview:

The manual pallet truck hydraulic pump core is an integrated hydraulic unit, typically comprising a pump cylinder, piston, sealing components, check valve, safety valve, and hydraulic oil chamber. Its compact design ensures reliable performance under frequent manual operation and high load pressure.

2. Core Functions and Working Principle:

Energy Conversion: Operating the handle drives the internal mechanism, causing the piston to reciprocate within the pump cylinder, generating pressure.
Hydraulic Drive: The piston movement compresses the hydraulic oil, pushing the load-bearing piston (main piston) upwards, achieving fork lifting.
Check and Pressure Regulation: The internal check valve ensures pressure maintenance, keeping the load at the desired height; the safety valve prevents system overpressure.
Lowering Control: A release valve (usually integrated with or separate from the pump core) controls the hydraulic oil return, enabling smooth lowering.

3. Key Components and Materials:

Pump Cylinder and Piston: Made of high-strength alloy steel, precision ground and chrome-plated to ensure hardness and smoothness, reducing wear.
Sealing System: Composed of multiple specialized oil seals (such as piston seals, rod seals, and guide rings) to prevent hydraulic oil leakage, crucial for long-term performance and maintenance-free operation.
Valve Components: Precision-machined steel check valves and safety valves ensure accurate opening and closing pressure and flow control.
Hydraulic Oil: High-quality anti-wear hydraulic oil ensures stable performance and system lubrication across a wide temperature range.

4. Main Technical Parameters and Model Matching:

Applicable Tonnage: Typically covers mainstream pallet truck models of 1.5 tons, 2.0 tons, 2.5 tons, 3.0 tons, and 5.0 tons.
Stroke and Pressure: Different pump core models have different strokes and rated working pressures, requiring matching with the vehicle model.
Installation Interface: The pump core's installation dimensions, oil port threads, and connection method must perfectly match the original frame.
Materials and Process: High-strength steel, professional heat treatment process, and high-precision machining.

5. Product Advantages (Highlights as a High-Quality Supplier):

Excellent Durability: High-quality materials and hardening treatment provide wear resistance and extend service life. Efficient Lifting Performance: Optimized design, fast lifting speed, and effortless operation.
Reliable Sealing: Uses well-known brands or high-performance seals to prevent leaks and reduce failure rates.
Wide Compatibility: Available in various models, compatible with mainstream domestic and international manual pallet trucks (and various replacement parts).
Convenient Maintenance: Modular design, easy replacement, and individual repair or replacement of components, reducing equipment downtime and overall costs.

6. Application Scenarios:

Mainly used for manual hydraulic pallet trucks in:

Manufacturing and Assembly: As a core component of new vehicles.
Maintenance and Repair: Replacing old pump cores due to seal wear, internal parts damage, piston scratches, or performance degradation from long-term use.
Performance Upgrade: Replacing old equipment with high-performance pump cores to restore or improve handling efficiency.
