One power unit. Two distinct hydraulic applications. More possibilities for demanding field operations. The ZONDAR 27HP hydraulic power unit expands the application possibilities of our ZONDAR hydraulic power units for demanding field operations.
Hydraulic breaking tools and high-capacity submersible pumps do very different jobs. One relies on high hydraulic pressure to generate powerful breaking, cutting, or splitting force. The other requires a high volume of hydraulic oil at a comparatively lower working pressure to drive large-volume water transfer.
Traditionally, choosing a hydraulic power source means starting with the requirements of a specific tool. But what if one power unit could accommodate both types of applications through a compatible hydraulic configuration?
Meet the ZONDAR 27HP Hydraulic Power Unit, developed for applications ranging from handheld hydraulic rock drilling and high-pressure metal demolition to hydraulic splitting, rescue operations, and high-volume water pumping.
What makes this model worth a closer look is not simply its 27HP engine rating. It is the opportunity to support two very different categories of hydraulic equipment: high-pressure tools for demanding breaking and rescue work, and low-pressure, high-flow hydraulic submersible pumps for moving large volumes of water.
For contractors, emergency response teams, drainage operators, and equipment distributors, this opens up a broader way to think about hydraulic power.
One Power Unit, Two Very Different Hydraulic Demands
Not all hydraulic equipment uses power in the same way.
A hydraulic splitting machine needs the pressure required to generate splitting force. A hydraulic rescue combination tool needs sufficient hydraulic pressure and compatible flow to perform cutting and spreading operations. A hydraulic submersible pump, by contrast, needs a suitable combination of hydraulic flow and pressure to drive its motor and deliver the required pumping performance.
These differences matter because engine horsepower alone does not determine whether a power unit can operate a particular tool.
The ZONDAR 27HP hydraulic power unit is intended to serve applications across these categories, with compatibility depending on the actual output specifications and hydraulic configuration.
Application 1: High-Pressure Hydraulic Breaking, Splitting, and Rescue

When breaking concrete, splitting rock, or carrying out metal cutting and spreading operations, the hydraulic system must deliver the pressure specified for the working tool.
The ZONDAR 27HP hydraulic power unit can be configured for compatible high-pressure hydraulic equipment, including:
- Hydraulic splitting machines for rock and concrete applications
- Hydraulic rescue combination tools for cutting and spreading
- Compatible hydraulic metal demolition tools
- Handheld hydraulic rock drills requiring approximately 20–30 L/min, subject to model specifications
For these applications, hydraulic pressure is central to the force the tool can generate, while flow affects operating speed and must remain within the tool’s permitted range.
This is why the power unit’s pressure capability, flow range, and hydraulic circuit design must be considered together.
For customers working in construction, demolition, emergency response, and infrastructure maintenance, the advantage is the possibility of using a compatible hydraulic power source across different high-pressure tool applications rather than treating every tool as an entirely separate power system.
Application 2: Low-Pressure, High-Flow Hydraulic Pumping

Breaking and rescue tools are only one side of the picture.
Water transfer presents a different challenge. When a construction site needs dewatering or an emergency team needs to move large volumes of water, pumping performance becomes the priority.
The ZONDAR 450 m³/h hydraulic submersible pump is designed for high-volume water transfer and has a specified hydraulic oil flow requirement of 60 L/min.
Here, the key consideration is not simply high pressure. The hydraulic power unit must provide the required oil flow at the pressure needed by the pump’s hydraulic motor.
This distinction is important. A power unit optimized for a high-pressure handheld tool does not automatically provide the correct output for a high-flow pump. Likewise, a high-flow pumping configuration should not be assumed suitable for every high-pressure tool.
The ZONDAR 27HP hydraulic power unit is intended to bridge these different application needs when its available output and circuit configuration meet the requirements of the selected equipment.
For drainage contractors, municipal maintenance teams, and emergency water management operators, this creates another potential use for the same power-unit platform: driving a compatible hydraulic submersible pump capable of moving up to 450 m³/h under its specified operating conditions.
Actual water output will depend on the pumping head, installation, and operating conditions.
Why This Difference Matters to Equipment Buyers
The distinction between high-pressure tools and low-pressure, high-flow pumps is more than a technical detail. It affects how buyers select, configure, and deploy their equipment.
For contractors: A compatible power-unit platform may support different types of work, from breaking and splitting to drainage, depending on the selected hydraulic configuration.
For rescue equipment suppliers: The power source can be evaluated alongside the required rescue tools, helping buyers establish whether the pressure, flow, and connection requirements are satisfied.
For drainage and water management operators: The same product family can be considered for high-volume pumping applications, provided the unit delivers the required flow and operating pressure.
For distributors and project procurement teams: Understanding the two hydraulic application categories makes it easier to assess equipment packages based on actual operating requirements rather than engine horsepower alone.
The key is not to assume that every tool can operate under one fixed setting. It is to select the appropriate configuration for the intended application.
27HP Is the Engine Rating. Hydraulic Output Is What Connects the Tool to the Job.
When evaluating a hydraulic power unit, it is tempting to compare models by engine horsepower alone. But the engine rating is only one part of the system.
For the ZONDAR 27HP hydraulic power unit, three factors are especially important.
1. Pressure capability
The power unit must deliver the working pressure required by the selected breaking, splitting, or rescue tool. Operating pressure must remain within the tool manufacturer’s specified limits.
2. Flow capacity
Different tools require different hydraulic flow rates. ZONDAR handheld hydraulic rock drills typically require 20–30 L/min, while the ZONDAR 450 m³/h hydraulic submersible pump requires 60 L/min.
3. Hydraulic circuit compatibility
Hoses, couplers, supply and return lines, valves, and any tool-specific circuit requirements must be compatible. If the application changes, the system may require a different configuration or adjustment.
These considerations explain why a power unit’s suitability for both high-pressure tools and high-flow pumping applications must be confirmed through its rated hydraulic performance data.
A More Flexible Approach to Hydraulic Equipment
For field operators, flexibility does not mean connecting every tool in the same way. It means having a power source that can be matched to different tasks without overlooking the needs of the equipment.
The ZONDAR 27HP hydraulic power unit brings together two important application directions: high-pressure hydraulic tools for breaking, splitting, and rescue operations, and high-flow hydraulic pumping for large-volume water transfer.
Combined with compatible ZONDAR equipment, this approach gives buyers more options when planning hydraulic systems for construction, demolition, emergency response, and drainage work.
Before selecting a configuration, buyers should confirm the required pressure, flow, duty cycle, and hydraulic connections for their intended tools. For the 450 m³/h submersible pump, the specified 60 L/min hydraulic flow requirement is a key starting point.
