Your VFD Solution is Here: Why Pre-Engineered is Smarter Engineering

In the world of hydraulic power unit design, customization often feels like the only path. You select a drive, size an enclosure, source the components, and manage the panel wiring and integration. This “engineered-to-order” (ETO) process provides ultimate flexibility, but it comes at a cost: long lead times, complex quoting, and significant engineering overhead.

But what if your application uses a standard variable displacement or fixed displacement pump? What if you need the proven energy savings of a variable frequency drive (VFD) without the ETO timeline?

This is where smarter engineering prevails. Introducing the Bosch Rexroth CytroCab, a pre-engineered packaging program that puts our industry-leading Sytronix VFD technology into a standardized, ready-to-integrate cabinet. It’s the fastest way to bring intelligent, efficient hydraulic power to your machine.

Standardization: Your Competitive Advantage

The core idea behind the CytroCab is simple: by pre-engineering the most requested drive configurations and options, we can dramatically shorten delivery times and simplify the entire procurement process.

Instead of starting from a blank sheet, you start with a proven, reliable base configuration:

  • A Bosch Rexroth EFC 5610 Variable Frequency Drive
  • Industry-leading Sytronix pump control software
  • A rugged, NEMA 12-rated enclosure
  • Fused circuit protection (upgradable to fused disconnect)
  • Thermostatically controlled cooling

This isn’t a limitation; it’s an accelerator. It removes the variables and guesswork from panel design, allowing you to get standard pricing and faster delivery, moving your project forward with confidence and speed.

The Power of Sytronix: More Than Just a Drive

At the heart of every CytroCab is our Sytronix control software, a specialized firmware designed to unlock the full potential of your hydraulic system. When paired with a Bosch Rexroth pump, Sytronix isn’t just spinning a motor; it’s intelligently managing power.

Massive Energy Savings: Sytronix automatically reduces motor speed during low-flow or no-flow periods, slashing energy consumption compared to traditional, fixed-speed power units.

Reduced Noise: Lower average motor speeds mean a quieter machine and a more comfortable, productive work environment.

Longer Component Life: Reduced wear on the motor and pump bearings leads to increased uptime and a lower total cost of ownership.

Intelligent Pump Protection: With features like leakage and thermal detection, Sytronix actively protects your pump, enhancing the reliability of your entire system.

Configured for Your Needs

Starting with the base model, the CytroCab offers a focused set of powerful options to tailor the solution to your specific machine requirements. Need local start/stop controls and status lights? The Local Control Kit (LC) adds them directly to the door. Need to monitor HPU sensors or add advanced supervisory functions? The PU option is designed for it.

For modern, connected machinery, the Ethernet Communication Kit (EC) provides a direct link to your plant-wide network, supporting protocols like Ethernet/IP, Profinet, and EtherCAT.

The Smart Choice for Efficient Hydraulics

The CytroCab is the ideal solution for end-users, machine builders and system integrators who need the benefits of a VFD without the cost and complexity of a full ETO build. It combines the reliability of Rexroth components, the intelligence of Sytronix software, and the speed of a standardized, pre-engineered solution.

The Hidden Cost of “Always On” Hydraulics—And How to Fix It

Your hydraulic pump is working hard right now. Even when your machine isn’t.

If you’re running fixed displacement pumps, they’re delivering full flow every moment they’re spinning—whether your system needs 100% capacity or 10%. It’s like driving with your foot on the gas and using only the brake to control speed. It works, but it’s incredibly wasteful.

The Energy Waste Problem Nobody Talks About

Here’s what most plant managers don’t realize: a typical fixed displacement hydraulic system wastes 30-40% of its input energy during normal operation. That energy doesn’t just disappear—it becomes heat that your cooling system has to remove, creating a double cost.

Let’s put numbers to it. A 50 HP hydraulic power unit running two shifts (4,000 hours/year) at $0.12/kWh costs roughly $18,000 annually to operate. If 35% of that is waste, you’re literally throwing away over $6,000 per year, per machine.

Multiply that across your facility.

The Smarter Alternative

Variable displacement pumps like the Bosch Rexroth A15VSO Series 12 solve this problem elegantly: they only produce the flow your system actually needs at any given moment.

When your press is holding pressure but not moving? The pump swivels to minimal displacement, maintaining pressure with minimal flow. When you need full power for rapid advance? The pump instantly adjusts to maximum displacement. It happens automatically, hundreds of times per cycle.

The result:

  • 30-40% lower energy consumption in typical industrial applications
  • Reduced heat generation means smaller coolers and longer oil life
  • Quieter operation when running at reduced displacement
  • Extended component life due to lower thermal stress
The Energy Waste Problem Nobody Talks About

It’s Not Just About Saving Energy

Yes, the energy savings are compelling. But variable displacement brings other advantages that fixed pumps simply can’t match.

  • Precise Control: Need to vary press closing speed based on part thickness? Simple with proportional control. Want to sequence multiple actuators smoothly? Load-sensing makes it effortless.
  • System Flexibility: One variable pump can replace multiple fixed pumps with complex valve circuits, simplifying your hydraulic schematic and reducing potential leak points.
  • Modern Connectivity: With optional sensors, today’s variable pumps aren’t just hydraulic components—they’re smart devices that report operating status, predict maintenance needs, and integrate with your machine control.

The Question Isn’t “If” But “When”

The technology has matured. The energy savings are proven. The payback periods are measured in months.

The real question for manufacturers isn’t whether variable displacement makes sense—it’s why they’re still paying to run inefficient systems.

If you’re still operating fixed displacement pumps on variable load applications, you’re choosing to waste money every single shift. The A15VSO Series 12 provides a straightforward path to eliminate that waste while improving machine performance.

Curious about the potential savings in your facility? A Bosch Rexroth applications specialist can evaluate your current system and calculate your expected ROI. Most manufacturers are surprised by how quickly these pumps pay for themselves.

More Than a Pump: Why the A10VSO is Still the Heart of High-Power Machines

What do a 100-ton excavator, a forestry harvester, and a concrete pump truck have in common? They all rely on a hydraulic pump to do the heavy lifting, and for decades, one name has defined reliability in this space: the A10VSO.

But in a world of smart, connected everything, why does this classic workhorse still dominate? Because it solves the three problems that matter most to machine builders and operators: Power, Flexibility, and Uptime.

The Power Problem

High-power machines need to move heavy loads quickly and precisely. This requires a pump that can deliver high pressure and flow without fail. The A10VSO Series 32 is an optimized medium-pressure powerhouse, providing a nominal pressure of 280 bar for continuous use. This raw power, combined with fast control response times, gives operators the dynamic performance needed for demanding tasks.

The Flexibility Problem

Modern machines needs are unique to their application, which can require different pumps for each build resulting in multitudes of different configurations. This can be diifficult to track and manage. The A10VSO’s brilliant solution is its flexible universal through drive capability. Note only are all the through drives rated to 100% capability the flexibility offered by the universal through drive design allows a customer to streamline their inventory, keeping track of less part numbers and allowing for easy through drive conversions in the field. A single pump can be used as a base to create multiple different pump stacks; this brings flexibility back to the designers, headache free conversions in the field, and ease of mind to purchasers.

The Uptime Problem

Unplanned downtime is the enemy of profitability. A failed pump can bring an entire operation to a standstill. The A10VSO’s legendary reputation is built on its durability. Its robust swashplate design, high-quality bearings, and precision manufacturing mean it’s built for a long service life, even in the harshest conditions. It’s the kind of component you install and forget about—which is the highest praise a pump can receive.

Evolving with the Times

The A10VSO series 32 is a modern pump that respects and improves upon its heritage in many different areas; efficiency, noise and reliability. It’s available with a wide range of controls, from simple pressure compensators to sophisticated electro-proportional (EP) versions that integrate seamlessly with modern electronic control systems. This allows it to serve as the reliable foundation for both traditional and “smart” machine concepts.

The A10VSO is more than just a pump. It’s a problem-solver, an enabler of compact design, and a guarantee of uptime. It’s the trusted, powerful heartbeat inside the machines that build and shape our world.

Downsize Your Drive, Not Your Power: The A3V Pump Changes the Sustainability Equation

For years, the path to sustainability in industrial hydraulics seemed to involve trade-offs. Gaining energy efficiency often meant complex system designs or accepting limitations. But what if you could achieve massive energy savings while also reducing investment costs, simplifying your machine build, and improving performance?

This is the new reality made possible by the Bosch Rexroth A3V pump platform, a highly efficient, high-speed variable displacement pump designed specifically for modern, speed-controlled industrial applications.

The Speed-to-Torque Revolution

The fundamental principle behind the A3V is a game-changer for machine design. In a speed-variable pump system, the required motor torque is directly related to the pump’s displacement and speed. By designing the A3V to operate reliably at exceptionally high speeds—up to 4000 rpm—we’ve flipped the traditional design equation.

This higher speed allows the pump to achieve the same flow rate with a smaller displacement, which in turn reduces the required motor torque by up to 30%.

What does this mean for you?

  • Downsize Your Motor: You can now use a smaller, less expensive servo motor.
  • Reduce Drive Costs: A smaller motor often allows for a smaller, more cost-effective converter.
  • Eliminate Liquid Cooling: In many cases, the smaller servo motor can be air-cooled, eliminating the cost and complexity of water-cooling circuits.

The result is a direct reduction in both initial investment cost and long-term operating costs.

Efficiency You Can Measure (And Hear)

The A3V platform isn’t just fast; it’s a new benchmark for efficiency in medium-pressure hydraulics. With a total efficiency of up to 93%—five percentage points higher than previous generations—it minimizes energy losses during operation. For cyclic applications like injection molding or presses, this can translate to overall energy savings of up to 80% compared to constant-speed systems.

We also engineered the A3V for quieter operation. Its design significantly reduces pressure pulsation, a primary source of hydraulic noise. This leads to a quieter machine, a more comfortable working environment, and less vibrational stress on the entire system.

Built for the Future of Hydraulic Drives

The A3V platform is purpose-built for the demands of modern electro-hydraulic systems.

  • Recuperation Ready: In applications like lowering a lifting platform or counter-holding a die cushion, the A3V can act as a motor, driving the servo motor as a generator to feed power back into the grid or intermediate circuit.
  • Unlimited Start/Stop: Designed for highly cyclic applications, it has no restrictions on start/stop cycles or prolonged pressure holding.
  • Dynamic and Variable: The combination of variable displacement and variable speed allows the system to achieve any operating state with optimized energy use, from high-flow movements to high-pressure holding with minimal torque.

The Smart Choice for Sustainable Hydraulics

The A3V pump platform proves that sustainability and cost-efficiency can go hand-in-hand. By enabling the downsizing of core drive components while delivering best-in-class performance, it represents the next generation of intelligent, medium-pressure industrial hydraulics.
