Hydraulic Pumps for Excavators & Heavy Machinery

Hydraulic pumps for excavators are the primary energy converters of your machine. While internal combustion engine power provides the initial rotation, it is the hydraulic pump that transforms this force into fluid power. By moving hydraulic fluid under extreme pressure, these pumps enable the lifting and digging capabilities of all heavy machinery.

Reliable hydraulic pumps are essential for maintaining peak system performance. When pump efficiency drops, it places a parasitic load on the engine, affecting everything from your air-fuel mixture to your overall fuel injection efficiency.

Collection: Hydraulic Pumps

The Power Source: From Engine to Fluid

In most internal combustion engines, the crankshaft drives the pump gear. This mechanical connection means that the health of internal engine parts, such as connecting rods and the cylinder wall, directly impacts your hydraulic output. As the pistons move within the engine, they generate the torque necessary to spin the pump's internal rotors.

To keep the system running smoothly, a stable electrical power system is required to manage electronic regulators. Without proper electrical system maintenance, the sensors that monitor flow rates can fail, leading to pressure spikes that stress both the hydraulic lines and internal engine components.

Protecting the Hydraulic and Electrical System

The synergy between the cooling system and the hydraulics is vital. If the hydraulic pump overheats, it can thin the oil and damage seals, much like how a failing oil pump or a clogged oil filter can destroy a gasoline engine.

To ensure electrical safety, modern machines use circuit breakers to protect the electrical components that control pump displacement. These breakers prevent surges from damaging the sensitive solenoids that act as a moving part within the hydraulic control valves.

Comprehensive Hydraulic Pump Range

We offer a wide selection of aftermarket hydraulic pumps designed to meet or exceed OEM standards. These units are built to withstand the high-vibration environments of mining and construction.

  • Piston Pumps: High-efficiency units where pistons move to provide variable flow rates.
  • Gear Pumps: Simple, robust designs that function as a reliable power source for auxiliary circuits.
  • Pilot Pumps: Low-pressure pumps that ensure your control valve opens with precision.

Proper regular maintenance of these pumps, including checking the oil filter and ensuring the cooling system is clear, is the best way of improving performance and extending the life of your fleet.
