Pumping Applications
Frequently Asked Questions
Selecting the right pump is not just about flow rate or pressure — it is about understanding the application as a whole.
In this section, we address common questions related to pump selection, hydraulic requirements, typical applications and system integration. Our goal is to help you identify the most suitable pump and configuration for your specific needs, whether you are operating in the field or designing an integrated system.
If your application requires more detailed guidance, we work closely with our customers to evaluate operating conditions and provide practical recommendations based on real-world experience.
Which pump is suitable for my application?
How do I choose the correct pump for my application?
Choosing the correct pump starts with understanding the application rather than the pump itself. Key factors include the type of liquid being pumped, required flow rate, pumping height, solids content, duty cycle and available hydraulic power. Mobile use, emergency operation or system integration may also influence the selection.
We help our customers evaluate these factors and recommend a pump configuration that matches real operating conditions, ensuring reliable performance without oversizing or unnecessary complexity.
What flow rate and head do I need?
The required flow rate depends on how quickly the liquid needs to be moved, while head is determined by the total pumping height, hose length, pipe diameter and system losses. In practice, longer hoses, elevation changes and restrictions can significantly affect performance.
By understanding the application layout and operating conditions, the pump can be selected to deliver sufficient flow at the required head without operating outside its optimal range.
Can the pump handle dirty water, slurry or solids?
Yes. Reini hydraulic submersible pumps are designed to handle dirty water, slurry and media containing solids, depending on the pump model and configuration. Material selection, impeller design and clearances are matched to the type of media being pumped.
For applications involving abrasive materials, fibrous content or high solids concentration, selecting the correct pump model is essential to ensure durability and reliable operation.
Which pump size fits my machine or system?
Pump size is primarily determined by the available hydraulic flow and pressure from the machine or system powering the pump. Tractors, excavators, loaders, trucks and hydraulic power units all have different capabilities that must be considered.
By matching the pump’s hydraulic requirements to the available power source, the pump can be integrated efficiently into mobile machinery or fixed systems without overloading the hydraulic circuit or compromising performance.
Can my machine power the pump?
What hydraulic flow and pressure are required?
Hydraulic flow and pressure requirements depend on the pump model and the desired performance. Flow primarily determines the pump’s output capacity, while pressure affects the ability to overcome pumping height and system losses. Each pump is designed to operate within a specific hydraulic range to ensure efficient and reliable operation.
We recommend selecting a pump that matches the available hydraulic capacity of the power source rather than operating at maximum limits.
Can the pump run on a tractor / excavator / loader?
Yes. Reini hydraulic submersible pumps are commonly powered by tractors, excavators, loaders and other mobile machinery equipped with suitable hydraulic outputs. The key requirement is that the machine can provide sufficient hydraulic flow and pressure within the pump’s operating range.
For mobile applications, we help verify compatibility between the pump and the machine to ensure safe and efficient operation.
Is a separate hydraulic power unit needed?
In many cases, a separate hydraulic power unit is not required, as the pump can utilize the existing hydraulic system of the machine. This makes the solution particularly well suited for mobile and field applications.
For stationary installations or applications without an available hydraulic power source, a dedicated hydraulic power unit can be used to provide consistent performance.
How does hydraulic power affect performance?
Hydraulic power directly influences the pump’s flow rate and ability to handle head and system losses. Higher hydraulic flow increases pumping capacity, while sufficient pressure is required to maintain performance under load.
Operating the pump within its recommended hydraulic range ensures optimal efficiency, reliability and service life, especially in demanding or continuous-duty applications.
How is the pump installed and integrated?
How is the pump mounted?
Reini hydraulic submersible pumps are typically suspended directly into the pumping location using a chain, rope or mounting frame, depending on the application. In mobile use, the pump is often handled by the host machine, such as a tractor, excavator or loader.
For integrated systems and OEM applications, the pump can be mounted using custom brackets or frames designed to suit the specific installation and operating conditions.
What hose and pipe connections are required?
The pump is connected using standard pressure-rated discharge hoses or pipes suitable for the pumped media and operating pressure. Hose diameter and length should be selected to match the required flow rate while minimizing friction losses.
Proper hose routing, secure fittings and adequate strain relief are important to ensure safe operation and consistent performance.
Can the pump be integrated as an OEM component?
Yes. Reini hydraulic submersible pumps are widely supplied as OEM components and integrated into mobile machines, pumping units and custom-built systems. Their hydraulic drive, compact design and flexible mounting options make them well suited for system integration.
We support OEM customers with technical documentation and application guidance to ensure seamless integration into their systems.
What should be considered in continuous or system use?
For continuous-duty or system-based applications, factors such as duty cycle, hydraulic oil cooling, filtration and overall system efficiency should be considered. The pump should operate within its recommended hydraulic range to avoid excessive wear and heat buildup.
Proper system design and regular maintenance help ensure reliable long-term operation in demanding environments.
How does it perform in real use?
How durable is the pump in abrasive conditions?
Reini hydraulic submersible pumps are designed for demanding applications involving dirty water, slurry and media containing solids.
Robust materials and a simple mechanical design support reliable operation in real working conditions where contamination and suspended solids are present.
For applications involving highly abrasive materials or extreme solids content, pump suitability should always be evaluated case by case. Selecting the correct pump model and configuration is essential to ensure reliable operation and acceptable service life.
What maintenance is required?
Maintenance requirements depend on the application and operating conditions, but are generally straightforward. Regular visual inspection, checking hoses and connections, and ensuring clean hydraulic oil help maintain reliable operation.
Depending on the pump model, certain components may require periodic greasing as part of normal maintenance. In demanding or continuous-duty applications, it is also recommended to replace specific wear-related seals preventively to ensure reliable operation and avoid unplanned downtime.
Wear parts are designed to be serviceable, allowing maintenance to be carried out efficiently without complex procedures.
How easy is servicing and spare parts availability?
Reini pumps are designed with serviceability in mind. Common wear parts can be accessed and replaced without specialized tools, reducing downtime in the field.
Spare parts and technical support are available to support long-term operation, especially for pumps used in continuous or critical applications.
Is the pump suitable for continuous operation?
Yes, Reini hydraulic submersible pumps are suitable for continuous operation when properly selected and installed. Continuous use requires attention to hydraulic oil cooling, filtration and system design to maintain stable operating conditions.
Operating the pump within its recommended limits helps ensure reliable performance and long service life.
