How Does a Water-Powered Pool Lift Work? The Science Behind the Gallatin Hydraulic Lift
Updated: October 2026
______________________________________________________
What if the same water pressure that flows through your facility's plumbing could also lift a person safely in and out of a swimming pool?
That's exactly how the Spectrum Aquatics Gallatin Hydraulic Water-Powered Pool Lift works.
No batteries to charge. No electric motor on the lift. No complicated electrical system. It harnesses water pressure through a hydraulic cylinder to provide smooth, dependable access to swimming pools and spas.
But how does it actually work? Let's take a closer look at the science behind water-powered pool lifts and why this technology makes so much sense for commercial aquatic facilities.
What Is a Hydraulic Water-Powered Pool Lift?
A hydraulic water-powered pool lift is an accessibility device that uses pressurized water to raise and lower a person into and out of a swimming pool.
Unlike battery-powered pool lifts, which rely on electrical energy to operate a lifting mechanism, the Gallatin uses pressurized water supplied through the facility's plumbing system.
When water enters the lift's hydraulic cylinder, it creates the force needed to raise the seat. When the control valve releases that pressure and lets water exit, the seat descends in a controlled manner.
This simple application of hydraulic technology that eliminates the need for batteries, charging stations, and electric lifting motors.
How Does the Gallatin Hydraulic Water-Powered Pool Lift Work?
The secret behind the Gallatin is a basic principle of physics: water under pressure can generate tremendous force.
The Gallatin uses this principle through a large stainless steel hydraulic cylinder and piston.
Here's what happens during operation.

Step 1: Water Pressure Supplies the Power
The Gallatin connects to a pressurized water supply, typically through a hose connected to the facility's plumbing.
The lift is designed to provide its full 400-pound lifting capacity with a continuous water pressure of 55 pounds per square inch (PSI).
That pressure supplies the energy needed to operate the lifting mechanism.
Step 2: Water Enters the Hydraulic Cylinder
When the user moves the control valve to the raising position, pressurized water enters the hydraulic cylinder.
Inside the cylinder, water pressure moves the piston.
As pressure builds, the water pushes the piston upward.
This is the fundamental principle behind hydraulic lifting: pressure acting over a surface area creates force.
Step 3: Water Pressure Raises the Seat
As pressurized water pushes against the piston, the lifting mechanism extends and raises the Gallatin's seat.
The large-diameter cylinder allows the lift to generate significant lifting force using ordinary pressurized water.
At 55 PSI, the Gallatin is rated to lift up to 400 pounds.
And because the lift uses water pressure rather than a battery-powered motor, there's no battery to recharge between uses.
Step 4: The Control Valve Manages Movement
The Gallatin features a manually operated control valve that allows users to raise, lower, or stop the seat. Turning the valve counterclockwise raises the seat. Turning it clockwise lowers the seat. Returning the valve to its intermediate position stops movement.
The lift can be operated from the deck or the water, supporting independent use by individuals who need accessible pool entry and exit.
Step 5: Releasing Water Pressure Lowers the Seat
To lower the seat, the control valve releases water from the hydraulic cylinder.
As water exits, the piston retracts, and the seat descends.
The hydraulic system controls the movement without any electric components.
The result is a straightforward lifting process powered by water pressure rather than electricity at the lift itself.
How Much Water Pressure Does the Gallatin Need?
Water pressure is an important consideration when selecting a hydraulic pool lift.
The Gallatin is rated for a maximum lifting capacity of 400 pounds at a continuous 55 PSI water pressure.
The lift can also operate at lower pressures, although its rated lifting capacity decreases accordingly.
| Available Water Pressure | Rated Lifting Capacity |
|---|---|
| 45 PSI | 300 lbs. |
| 50 PSI | 350 lbs. |
| 55 PSI | 400 lbs. |
For facilities that cannot consistently maintain the recommended water pressure, Spectrum Aquatics offers an optional Spectra-Force Pressure Booster System.
The booster system uses a pump to maintain the water pressure needed to operate the lift. The lift itself remains hydraulically water-powered, although the optional booster requires electricity.
Before installation, facilities should verify their available water pressure and ensure the supply meets the lift's operating requirements.

Why Choose a Water-Powered Pool Lift Instead of a Battery-Powered Lift?
Battery-powered pool lifts are an excellent accessibility solution for many aquatic facilities. However, hydraulic water-powered lifts offer several advantages for facilities that have an appropriate pressurized water supply.
No battery charging. The Gallatin doesn't rely on rechargeable batteries, so staff doesn't need to maintain a charging schedule or remember to reinstall a battery.
Zero electrical components. Gallatin only requires water!
Ready for daily use. With the water supply connected, adequate pressure available, and the lift properly maintained, the Gallatin is ready to operate without waiting for a battery to charge.
Designed for demanding aquatic environments. The Gallatin features a durable stainless steel lifting mechanism designed for commercial swimming pools and spas.
Supports independent accessibility. Controls accessible from both the deck and water allow users to operate the lift independently when appropriate.
For municipal aquatic centers, community recreation facilities, fitness centers, and therapy pools, these advantages can make hydraulic technology an appealing long-term accessibility solution.
Does a Hydraulic Water-Powered Pool Lift Require Electricity?
The Gallatin does not require electricity to operate its lifting mechanism when the facility's water supply provides adequate pressure.
That is one of its biggest advantages!
The energy needed to lift a person comes from pressurized water, not an onboard battery or electric motor.
