These pumps convert electrical energy into hydraulic power. An electric motor drives the hydraulic pump, pressurizing fluid from a reservoir.
Key points:

- Powers hydraulic cylinders, motors, and actuators
- More precise control compared to other pump types
- Compact, quiet operation
- Common in manufacturing and construction equipment


In simple terms: electricity → rotational motion → hydraulic pressure → usable force.

We reach for these compact power packs any time a project needs a single punch of high pressure rather than a steady flow. Typical calls include torquing nacelle bolts on wind towers, snugging bridge cable tendons, bump-lifting railcars for wheel swaps, or lending a shop press a momentary boost during a breakdown. Their 10K PSI ceiling and suitcase-style frames make it easy to shuttle one pump between scattered work zones.

Most units we stock run on 115 V or 230 V single-phase current – typically up to about twelve amps when the electric hydraulic pump’s motor is under load. Larger two-horsepower models pull closer to twenty amps, and a few DC versions clamp straight to a truck battery for remote repairs. Verify continuous amperage, since low voltage can overheat windings fast. We can help you choose the right cord cap or generator adapter with the pump.

Yes. In a two-speed design, the pump starts by moving oil quickly at modest pressure. Once the cylinder hits resistance, it switches into a slower, high-pressure mode, saving time on every cycle. Adjustable relief valves – or on some electric hydraulic pump models, a digital set point – let you cap system PSI at the level your application requires. Remote pendants keep the operator clear of pinch points while making tweaks on the fly.

Key maintenance steps include:

- Regular fluid checks for contamination
- Hose and seal inspection for leaks
- Filter replacement 
- System monitoring for pressure fluctuations. 
- Operating within the rated temperature and pressure range

Common causes include:

- Low hydraulic fluid levels 
- Clogged filters
- Excessive loads
- Poor ventilation 


To prevent this, keep the electric hydraulic pump clean, maintain proper fluid levels, and ensure proper placement where airflow keeps the motor cool.
