Exact technical values must be confirmed for each part number. Different power steering pump models may have different operating specifications.

Documented Power Steering Pump Performance Testing

Product performance should be supported by actual testing rather than relying only on material descriptions or visual inspection.

A supplier-issued finished-product test report dated March 8, 2026, documents the performance inspection of a power steering pump model.

The recorded tests include running-in, impact pressure, safety valve performance, volumetric efficiency, full-load flow, and air-tightness.

Representative Finished-Product Test Results

Test item	Test conditions	Recorded results
No-load Starting Flow	600 r/min	6.23 L/min
Impact Pressure	600 r/min, 5 impacts	11.66 MPa
Safety Valve Pressure	Multiple speeds, 5-second holding periods	11.60–11.70 MPa
Pressure Fluctuation	Safety valve test	0.04–0.11 MPa
Volumetric Efficiency	600 r/min, 0.5 Pmax	90%
Full-Load Flow	1000 r/min, 0.85 Pmax, 6 seconds	5.56 L/min
Air-Tightness Test	0.2 MPa, 10 seconds	No air bubbles

These figures represent the recorded results of one tested product model and should not be interpreted as universal specifications for all GDST power steering pumps.

What Do These Test Results Mean?

Volumetric Efficiency

The tested pump achieved a volumetric efficiency of 90%, exceeding the report’s specified minimum requirement of 80% under the stated test conditions.

Safety Valve Pressure Stability

The recorded pressure fluctuations ranged from 0.04 to 0.11 MPa, within the specified maximum fluctuation of 0.5 MPa.

Hydraulic Power Steering vs. Electric Power Steering Pumps

When sourcing aftermarket steering components, it is important to distinguish between hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems.

Although these terms are sometimes used interchangeably in online searches, they refer to different technologies and components.

1. Hydraulic Power Steering (HPS)

Hydraulic power steering uses a pump to pressurize steering fluid and provide assistance to the steering gear or rack.

In traditional systems, the pump is mechanically driven by the engine through a belt, gear, or shaft connection.

The hydraulic pump is an important replacement component in this system.

2. Electro-Hydraulic Power Steering (EHPS)

Electro-hydraulic power steering combines hydraulic assistance with an electric motor-driven pump.

Unlike traditional belt-driven hydraulic pumps, the pump is powered by an electric motor. However, the system still uses hydraulic fluid and hydraulic steering components.

The electric motor and hydraulic pump may be supplied as an integrated assembly.

3. Electric Power Steering (EPS)

Electric power steering uses an electric motor to provide steering assistance without relying on a conventional hydraulic pump.

Depending on the design, the electric motor may be integrated into the steering column, pinion, or steering rack.

A conventional hydraulic power steering pump is not a direct replacement for an EPS motor or steering assembly.

Comparison of HPS, EHPS and EPS

System	Power source	Uses hydraulic fluid	Main assistance component
HPS	Engine-driven belt, gear or shaft	Yes	Hydraulic power steering pump
EHPS	Electric motor driving a hydraulic pump	Yes	Electric motor-driven hydraulic pump assembly
EPS	Electric motor	No conventional hydraulic circuit	Electric motor and electronic control system

Looking for an Aftermarket Electric Power Steering Pump?

If you searched for an aftermarket electric power steering pump, the exact product you need may be an EHPS pump assembly rather than a conventional hydraulic pump.

To avoid ordering the wrong component, please send us:

• OE number or original part number
• Vehicle make, model, and year
• Product photographs
• Whether the original unit has an electric motor
• Available product identification markings

GDST’s listed power steering pump portfolio focuses on hydraulic pump configurations. EPS motors and complete electric steering systems should be treated as separate product categories, not as conventional hydraulic pump replacements.
