Piston Pump - Liebherr

Liebherr is a Swiss-German equipment manufacturer known globally for high-performance mining excavators, tower cranes, concrete pumps, and earthmoving machinery. Liebherr hydraulic systems are engineered for maximum durability in severe-duty applications, from construction sites to open-pit mining operations. At HE PUMP, we supply OEM-compatible Liebherr hydraulic pumps and engine components for the complete Liebherr equipment range. Every product is manufactured to Liebherr OEM specifications for drop-in fitment and includes 12-month warranty coverage.

Liebherr Equipment Coverage

We supply hydraulic pumps and engine components for the complete Liebherr equipment lineup:

  • Hydraulic Excavators: R914, R924, R934, R944, R954, R964, R974, R984 series — compact to large excavators for construction, quarrying, and material handling
  • Mining Excavators: R9150, R9250, R9350, R9400, R9800, R9980 series — massive mining excavators for open-pit mining operations, requiring high-flow, high-pressure hydraulic systems
  • Wheel Loaders: L524, L538, L542, L546, L550, L556, L566, L574, L580, L586 series — Liebherr wheel loaders known for hydrostatic drive and exceptional fuel efficiency
  • Bulldozers: PR734, PR744, PR754, PR764, PR774, PR784 series — Liebherr crawler tractors with hydrostatic drive and precision blade control

Available Liebherr Hydraulic Pump Products

Liebherr equipment relies on multiple hydraulic pumps for different functions:

  • Hydraulic Piston Pumps (Main Pumps): For Liebherr excavator main hydraulics, wheel loader implement circuits, and mining excavator primary circuits — high-pressure pumps delivering the power Liebherr equipment demands in severe-duty applications
  • Hydraulic Piston Pumps (Pilot Pumps): Supplying low-pressure control pressure for Liebherr hydraulic valve spools — allows precise, low-effort control of main hydraulic functions
  • Hydraulic Gear Pumps: For Liebherr charge pump circuits, steering pumps, and auxiliary hydraulics — reliable, cost-effective pumps for medium-pressure applications
  • Complete Pump Assemblies: Fully assembled pumps ready for bolt-on installation, including mounting flanges and drive couplings where applicable

Liebherr Engine Component Products

Liebherr manufactures its own diesel engines for many equipment models. We supply engine components for Liebherr engines and Cummins/MTU engines used in Liebherr mining equipment:

  • Engine Water Pumps: Coolant circulation pumps for Liebherr diesel engines — overheating in mining operations can cause catastrophic engine damage and massive downtime costs
  • Engine Oil Pumps (Lube Pumps): Lubrication system pumps for Liebherr diesel engines — low oil pressure causes rapid engine wear, particularly damaging for Liebherr's high-performance engines
  • Fuel Transfer Pumps: Fuel delivery pumps for Liebherr diesel engines — ensures consistent fuel supply to high-pressure injection system

Signs of Hydraulic Pump Failure in Liebherr Equipment

Watch for these warning signs that a Liebherr hydraulic pump is failing:

  • Reduced hydraulic power: Slow implement movement, inability to lift rated load — internal leakage across worn piston shoes and cylinder block
  • Increased pump noise: Rattling, knocking, or whining from pump area — piston shoes damaged or valve plate badly worn
  • Overheating hydraulic oil: System temperature rises rapidly under load — internal leakage generating heat through fluid bypass, particularly dangerous in mining operations
  • Metal particles in hydraulic oil: Magnetic drain plug or filter captures metal shavings — internal component wear debris
  • Loss of pilot control pressure: Implement control becomes stiff or unresponsive — pilot pump failure
