P5100-G100M-1 Carriage Lift Pump

XQF22 Aluminium Hydraulic Limiting Valve

• High-Power Hydraulic Output: Adopts a dual-stage vane pump design, delivering high flow rate at low pressure and high pressure at low flow rate, meeting both rapid lifting and heavy-load holding requirements. Ensures smooth and efficient carriage elevation even under full-load conditions.

• : Pump body crafted from high-strength cast iron (HT250) with precision machining, featuring excellent pressure resistance and impact resistance. Internal rotor and vanes made of wear-resistant alloy steel, extending service life under high-frequency operation.

• : Equipped with a built-in pressure relief valve and adjustable pressure regulating mechanism, enabling precise setting of maximum working pressure to prevent system overload. Pressure holding performance ensures no carriage drift during static loading, enhancing operational safety.

• Low-Noise & Energy-Saving Operation: Optimized internal flow channel design reduces fluid turbulence, operating noise <=68 dB(A) at rated speed. High volumetric efficiency (>=92%) minimizes energy loss, improving fuel economy for vehicle-mounted applications.

• : Compatible with mineral oil-based hydraulic fluids (ISO VG 32/46/68) and synthetic hydraulic oils, maintaining stable performance in diverse temperature and working conditions. Sealed design prevents fluid leakage and contamination.

• : Compact structure with standardized mounting flanges and inlet/outlet interfaces, enabling direct integration with existing hydraulic systems. Removable end cover facilitates internal component inspection and replacement, reducing maintenance downtime.

• :

    Pump Body: High-strength cast iron (HT250) – tensile strength >=250 MPa, Brinell hardness 187-255 HB, with anti-corrosion paint coating (thickness 15-20 μm) for protection against moisture and dust.

    Rotor & Vanes: High-carbon chromium steel (GCr15) – rotor quenched to HRC 58-62, vanes tempered to HRC 45-50, ensuring wear resistance and fatigue life under high-speed rotation (up to 3000 rpm).

    Seals: Fluorine rubber (FKM) – resistant to high temperature (up to 150℃), hydraulic oil, and aging, compatible with most hydraulic fluid types, ensuring leak-proof performance at maximum working pressure.

• :

    Maximum Working Pressure: 25 MPa (continuous operation), 31.5 MPa (peak pressure for short-term overload).

    Adjustable Pressure Range: 5-25 MPa (via external pressure regulating valve with locking nut for anti-loosening).

    Rated Flow Rate: 40 L/min (at 2000 rpm), 60 L/min (at 3000 rpm) – dual-stage flow design (low-pressure stage: 60 L/min @ 10 MPa; high-            pressure stage: 40 L/min @ 25 MPa).

    Pressure Holding Stability: <=0.5 MPa pressure drop per hour under static load, preventing carriage drift.

• :

    Speed Range: 800-3000 rpm (compatible with most vehicle engine power take-off (PTO) speeds).

    Volumetric Efficiency: >=92% (at rated pressure and speed), mechanical efficiency >=88%.

    Noise Level: <=68 dB(A) (measured 1 meter away from the pump body at rated working conditions).

    Response Time: <=0.8 seconds for lifting/lowering activation, ensuring rapid operation.

• :

    Operating Temperature Range: -30℃ to +120℃ – maintains fluidity and seal performance in extreme cold and high-heat environments.

     Storage Temperature Range: -40℃ to +150℃ – no structural deformation or material degradation during long-term storage.

     Installation Orientation: Horizontal (preferred) or vertical (within ±30℃) – compatible with diverse vehicle chassis layouts.

     Inlet/Outlet Interface: SAE 16 (1-1/2"-12 UN) female thread (inlet), SAE 12 (1-1/4"-12 UN) female thread (outlet) – thread accuracy Class 2B,    compatible with standard hydraulic fittings.

     Weight: Approx. 12.5 kg (net weight, excluding accessories) – compact design for space-saving installation.
