Power Packs

Hydraulic Power for Demanding Foundation Engineering Operations

Hydraulic equipment performance depends on more than engine output alone. The power pack must supply the required oil flow and pressure consistently while managing heat, filtration, control functions and changing operational loads. An incorrectly matched system can reduce equipment performance, interrupt working cycles and increase the risk of overheating or premature component wear.

OMS Hydraulic Power Packs are self-contained hydraulic power units developed to provide controlled hydraulic energy for demanding applications. The range supports OMS crane-suspended vibratory hammers, vibroflot equipment and other heavy-duty hydraulic systems requiring reliable pressure and oil flow.

The OMS PP Series extends from PP 218 to PP 1592. Depending on the selected configuration, the range provides oil flow capacities up to 2,000 l/min and system pressure ratings up to 400 bar. However, power pack selection must always follow the actual pressure, oil-flow and control requirements of the connected equipment.

How an OMS Hydraulic Power Pack Works?

A hydraulic power pack converts the mechanical output of a diesel engine into hydraulic energy. The engine drives the hydraulic pump system, which draws oil from the reservoir and supplies it to the connected equipment at the required pressure and flow.

Pressure and flow perform different functions within this process:

  • Oil flow determines how quickly the hydraulic motors and actuators can operate.
  • Hydraulic pressure provides the force or torque required to overcome the operational load.
  • Cooling capacity controls the temperature generated during continuous circulation and high-load operation.
  • Filtration protects pumps, valves, hydraulic motors and other precision components from contamination.
  • The control system regulates machine functions and allows the operator to monitor operating conditions.

These parameters must be evaluated as one system. Selecting a hydraulic power unit only according to engine power does not confirm compatibility with the connected vibro hammer, vibroflot or other hydraulic equipment.

OMS power packs are named according to the horsepower of their engines. Model names, engine specifications and available configurations may change depending on engine availability and project requirements. The appropriate unit must therefore be confirmed using the current technical specification and the connected equipment’s hydraulic demand.

System Configuration and Control Options

OMS Hydraulic Power Packs combine the components needed to generate, regulate and manage hydraulic energy within a single system. Depending on the project configuration, the hydraulic system can be designed with an open- or closed-loop arrangement.

Available operating interfaces include an integrated touchscreen and wired or wireless remote-control options. These controls allow the operator to manage the system from a suitable working position and follow essential operating conditions.

A remote-control module can also support internet-based software updates and power pack status monitoring. This capability helps OMS technical personnel assess the unit for service and maintenance purposes when the installed configuration and site connectivity permit remote access.

Power Packs for Crane-Suspended Vibratory Hammers

Crane-suspended vibratory hammers require a hydraulic power source capable of sustaining the specified oil flow and pressure throughout pile driving and extraction. Hydraulic compatibility affects vibration frequency, operational stability, clamp functions and the overall working cycle.

The SVR-NF Normal Frequency Series covers crane-suspended vibratory hammers for conventional pile driving and extraction operations. Within this series, the recommended power pack changes according to hammer size and hydraulic demand. The current OMS range includes pairings from PP 320 for the SVR 25 NF up to PP 1536 for the SVR 200 NF.

Projects close to buildings, utilities or other vibration-sensitive structures may require controlled start-up and shutdown. The SVR-VM Resonance-Free Variable Moment Series uses a phase-shifting system to support resonance-free starting and stopping. These machines also require power packs matched to their hydraulic and control architecture.

The hammer and power pack should consequently be treated as an integrated system rather than as independent machines. Hose arrangement, pressure losses, ambient conditions, clamp requirements and the expected working cycle must be included in the engineering assessment.

Power Packs for Vibroflot Equipment

Vibroflotation equipment uses hydraulic energy to drive the vibroflot probe during deep soil compaction and stone-column operations. Stable oil supply is important because the probe operates under changing resistance as it penetrates, compacts material and moves through different soil layers.

OMS offers Vibroflot 300-2 and Vibroflot 300-4 units for top-feed and bottom-feed configurations. According to the current OMS technical data:

  • The Vibroflot 300-2 is paired with the PP 218.
  • The Vibroflot 300-4 is paired with the PP 320.

The PP 218 provides a maximum oil flow of 232 l/min, while the PP 320 provides up to 460 l/min. Both listed vibroflot power pack configurations have a maximum pressure of 350 bar. The actual flow and pressure can be adjusted according to the operational requirement.

Equipment configuration must also consider whether the vibroflot is crane-suspended, leader-mounted or integrated with another carrier arrangement. Site-specific factors such as penetration resistance, working depth, feed method and continuous operating duration influence final system selection.

General Heavy-Duty Hydraulic Power Applications

Beyond vibratory hammers and vibroflotation, OMS Hydraulic Power Packs can be configured for general hydraulic power requirements in industrial machinery, construction equipment, heavy-duty construction, marine and offshore systems, agricultural machinery, oil and gas operations, and mining environments.

The catalogue range includes compact single-engine units and higher-output twin-engine configurations. Custom solutions can be evaluated where a project requires a particular capacity, pressure rating, hydraulic circuit or installation arrangement.

This broad application range does not mean that every power pack is automatically suitable for every hydraulic machine. Compatibility must be verified using the equipment’s continuous and peak oil-flow demand, operating pressure, return-line conditions, cooling requirement and control logic.

Engineering Criteria for Power Pack Selection

  1. Required Oil Flow
    The connected equipment’s specified operating flow should be the starting point. Insufficient flow may prevent the equipment from reaching its intended operating speed, while an oversized system requires appropriate flow regulation and system integration.
  2. Working and Peak Pressure
    The power pack pressure rating must cover the equipment’s operating requirement without exceeding the allowable limits of hoses, valves, motors, cylinders and auxiliary components.
  3. Continuous Duty and Thermal Load
    Long working cycles generate heat. Ambient temperature, load duration, hydraulic efficiency and cooler sizing must be considered together.
  4. Hydraulic Circuit Type
    Open- and closed-loop systems have different operating and control requirements. The selected circuit must correspond to the connected machine architecture.
  5. Engine and Emissions Configuration
    Engine configuration should be selected according to the operating region, project requirements and locally applicable emissions conditions. Availability may affect the final model designation and technical configuration.
  6. Site Layout and Control Method
    Power pack location, hose routing, transport dimensions, remote-control requirements and service access influence both safety and operational efficiency. Site-specific configuration, commissioning and operating procedures should be evaluated with the OMS Vibro technical team.
