DV Hydraulics designed and built a fully custom hydraulic system based on water instead of oil, specifically developed for a unique underwater environment in the entertainment sector.

The installation is part of a spectacular show element in the largest water show in the world, where all hydraulic actuators – including cylinders and motors – operate permanently under water at a depth of 7 meters in a swimming pool.

Although the HPU itself is not located underwater, all movements – including proportional control – are controlled from beneath the surface by a diver.

Operation takes place via a dedicated control panel with levers on the boat.

This called for a design in fully stainless steel, combined with pure water as hydraulic medium.

This makes the system completely leak-safe, even in sensitive environments like swimming pools where water quality and reliability are critical.

The installation has an installed power of 180 kW, proportionally controlled via frequency drives, and is built with redundancy to ensure maximum operational reliability.

Control is handled by a powerful Siemens S7-1517 PLC, connected to three HMI panels for safe, precise, and intuitive operation – even during live performances.

On the mechanical side, only high-quality, corrosion-resistant components were used:

Three stainless steel triple-action cylinders operate the masts, powered by a custom-designed RVS manifold block.

The system also includes four nickel-plated caterpillar drives with integrated stainless steel hydraulic motors, and two automatic hose reels, also driven by RVS hydraulic motors.

Key technical specifications:

• All actuators (cylinders, motors) operate permanently underwater (7 meters deep).

• Proportional movements and control are performed underwater.

• Full stainless steel construction for optimal corrosion resistance.

• Pure water as hydraulic medium – safe for use in swimming pools.

• 180 kW installed power, proportionally controlled via frequency drives powering CAT pumps.

• Redundant system design for maximum reliability.

• Siemens S7-1517 PLC with three HMI control panels.

• Three stainless steel triple-action cylinders with dedicated RVS manifold block for the actuation of the masts.

• Four nickel-plated caterpillar drives with RVS hydraulic motors.

• Two automatic hose reels driven by RVS hydraulic motors.

• Boat-based control panel for central operation.

• Delivered as a complete turnkey project.

This water-based hydraulic installation combines precision, durability, and safety in a challenging underwater environment.

It is designed for applications where absolute reliability, corrosion resistance, and environmental safety are essential.
