eReady pumps: where energy meets movement
With stricter emission rules, rising fuel costs, and the push toward cleaner machines, electrification is becoming a bigger subject in the world of hydraulics. In this shift, eReady pumps from Parker are becoming a key technology across construction, agriculture, transportation, and industrial machinery.
One solution that stands out in this transition are the Parker eReady pumps, designed specifically for modern electrified systems. These pumps combine the power density of hydraulics with the efficiency and control of electric drives, helping machines perform better while using less energy.
Understanding the shift toward electrification in hydraulics
Electrification plays a major role in building a low-carbon future. Traditional hydraulic systems rely heavily on internal combustion engines running at constant speeds. While effective, they often waste energy, generate noise, and require frequent maintenance.
Electric and electro-hydraulic systems work differently. Instead of running continuously, they deliver flow on demand, which reduces power loss and improves efficiency. Electro-hydraulic pumps can be up to 80% more efficient than traditional hydraulic pumps when used correctly.
Parker eReady pumps are built to work seamlessly with electric motors, inverters, and advanced control systems, making them ideal for hybrid and fully electric machines.
What are eReady pumps?
eReady pumps are hydraulic pumps optimized for electrification applications. They are designed to operate over a wide speed range and deliver precise control across different pressure and flow requirements.
Unlike conventional systems, eReady pumps are:
- Directly mounted to electric motors
- Compatible with variable speed drives
- Optimized for dynamic operation and energy recovery
- Designed to reduce noise, vibration, and energy losses
Where energy meets movement: smart system architectures
One of the biggest advantages of eReady hydraulic pumps is how flexible they are in system design. There are multiple system architectures for electrified machines:
1. Configured ePump systems
In this setup, electric motors drive hydraulic pumps directly, supplying flow only when needed. This improves overall system efficiency and reduces energy consumption.
2. Electro-hydrostatic actuators
These systems combine electric motors, pumps, and valves into compact units. They allow decentralized control, improve responsiveness, and even enable energy recovery during braking or lowering movements.
3. Centralized vs decentralized systems
- Centralized electric systems use one pump to power multiple functions.
- Decentralized systems use multiple smaller pumps for different functions, reducing losses and improving control.
Each architecture offers different benefits depending on the machine type, workload, and energy goals.

Applications of Parker eReady pumps
One reason eReady pumps are gaining attention is their wide range of real-world applications. There are several key industries where these pumps are already making an impact.
Construction equipment
Electric and hybrid construction machines benefit from quieter operation, reduced emissions, and better energy efficiency. eReady pumps are commonly used in excavators, loaders, and material handling equipment.
Agricultural machinery
Modern agricultural equipment requires precise control and long operating hours. eReady hydraulic pumps help reduce fuel consumption while maintaining high performance for harvesting, lifting, and steering functions.
Refuse trucks and street sweepers
Urban vehicles like refuse trucks and street sweepers need low noise levels and clean operation. Electric hydraulic pump systems are ideal for stop-and-go cycles and auxiliary functions.
Buses and coaches
Electro-hydraulic power steering and auxiliary hydraulic systems powered by eReady pumps improve efficiency while supporting fully electric drivetrains.
Vocational vehicles with ePTO
Vehicles with electric power take-off systems rely heavily on efficient hydraulic pumps. eReady pumps deliver reliable performance while reducing maintenance and downtime.
Key benefits of hydraulic eReady pumps
High energy efficiency
eReady pumps operate efficiently across a wide speed and pressure range. By delivering flow only when required, they significantly reduce energy consumption and extend battery runtime.
Low noise operation
Noise reduction is a major benefit. These pumps are engineered to reduce pressure pulsations, which lowers vibration and hydraulic noise. This is especially valuable in urban and indoor applications.
Improved performance and control
With optimized suction and port plate timing, eReady pumps maintain strong performance at both high and low speeds. They are suitable for dynamic operation where speed changes frequently.
Reduced total cost of ownership
Lower energy use, reduced wear, fewer components, and less downtime all contribute to a lower total cost of ownership over the machine’s lifecycle.
High reliability and durability
The pumps, motors, and inverters are perfectly matched, eliminating the need for extra adaptors. This improves system reliability and simplifies installation.
Parker’s eReady pump portfolio explained
Parker offers a broad range of fixed displacement and variable displacement hydraulic pumps, all optimized for electric drive applications.
Fixed displacement pumps
These pumps are cost-effective and work well with variable speed electric motors. Key options include:
- Bent axis piston pumps for high efficiency
- Vane pumps for low noise
- External gear pumps for cost-sensitive applications
They are ideal when the required flow can be controlled through motor speed.
Variable displacement pumps
Variable displacement piston pumps allow precise control of pressure, torque, and flow. This makes it possible to use smaller motors while maintaining performance.
They are especially useful when:
- Advanced control is required
- Energy optimization is critical
- Multiple operating conditions must be handled efficiently
Why eReady pumps are the future of hydraulic systems
eReady pumps prove that hydraulic systems can remain powerful while becoming cleaner, quieter, and more efficient. By combining electric motors with optimized hydraulic pumps, manufacturers can meet sustainability goals without sacrificing performance. From construction sites to city streets, eReady hydraulic pumps are helping machines do more with less energy.
