FAQs of Stainless-Steel Hydraulic Separator
1. What is the function of a stainless steel hydraulic separator?
From Caleffi Hydronic Solutions
The Plumberstar stainless steel hydraulic shunt is designed to address three fundamental requirements of heating and cooling systems: hydraulic balance, clean medium, and stable operation. It combines four core functions to deal with common system problems at the root, and it fits a wide range of industrial and commercial uses.
It separates flow and pressure between the primary side (heat or cooling source) and the secondary side (terminal equipment).
The shunt also ensures accurate distribution of flow. It supports 2 to 12 branches that can be customized as needed. Flow deviation is maintained within ±5%, which helps resolve issues such as uneven heating or cooling in commercial buildings and low heat output in floor heating systems. At the same time, overall system efficiency is improved.
Air and impurities are removed simultaneously. Cyclone gas-water separation reaches an efficiency of 99% or higher, reducing air pockets that weaken heat transfer. A removable stainless steel filter with 80–120 mesh captures more than 95% of solid particles. This protects valves and heat exchangers and cuts system failure rates by over 60%.
Energy use is also reduced. The smooth internal flow path keeps pressure loss at or below 0.03 MPa, much lower than the typical industry level of 0.08 MPa.
2. Does the hydraulic separator support flow regulation?
Adjustment options Each branch interface can be fitted with either a manual control valve or an electric control valve, depending on system needs. The manual version comes with a clear dial and offers an adjustment accuracy of ±5%. It is easy to read and simple to operate, making it a good fit for small and mid-size systems. The electric version supports PLC remote control and 4–20 mA signal feedback. It allows automatic flow control and works well with smart buildings and centralized industrial control systems.
Control principle Branch flow is controlled directly by adjusting the valve opening. At the same time, the internal flow channels are designed using optimized fluid dynamics, so each branch remains stable after adjustment, with no obvious fluctuation.
3. What is the manufacturing process of the Hydraulic Separator?
Integrated spinning forming The main body is made using an integrated spinning forming process. A single stainless steel plate is shaped in one setup under CNC control, with no secondary joining. This removes the weld points found in traditional spliced designs. As a result, overall strength increases by 40%, and tensile strength reaches at least 515 MPa.
CNC machining and optimized flow design Production is supported by eight automatic CNC lines. Core dimensions are controlled within ±0.02 mm. Thread connections, branch angles, and other key features comply with ISO 8015 requirements, ensuring the separator is compatible with systems from various brands. The internal flow path is designed using fluid simulation to ensure smooth transitions and eliminate dead zones. With electrolytic polishing, impurity buildup is reduced, and hydraulic resistance is kept to ≤0.03 MPa. This is 62.5% lower than the industry average, helping to cut system energy use by 10% to 15%.
Flexible production and fast customization The automated flexible line removes the limits of traditional batch production. Branch numbers and pipe sizes can be easily changed, and no additional mold cost is required for customization. Standard customized orders can be delivered within 30 days, about 40% faster than the industry norm. Even for small batches, process consistency is maintained. Size accuracy and sealing performance remain consistent across every unit, which is ideal for trial orders and large repeat orders in export projects.

4. What customization requirements does the Stainless-Steel Hydraulic Separator support?
Structured and sized to project needs
Shunt structure The standard design uses 2 to 8 branches. If the system requires more or fewer branches, it can be customized from 1 to 12. Branch sizes do not have to be the same. Branch angles and spacing can also be adjusted to suit the piping layout.
Pipe size options The main pipe can be manufactured in large diameters, ranging from DN200 to DN300. For compact systems, sizes below DN50 are also available. Branch connections are usually set between DN25 and DN100 and can be selected based on actual flow and load requirements.
Connection types BSPP, BSPT, and NPT threads are used as standard. If needed, the unit can also be supplied with flanged connections or socket welding ends to match existing piping systems.
Material selection Materials can be customized to meet specific working conditions and system requirements. Just contact us.
5. What is the difference between a stainless steel hydraulic separator and a carbon steel separator?
The primary differences between the Plumberstar stainless steel hydraulic shunt and a standard carbon steel shunt are evident in four key areas.
Application range Stainless steel shunts are suitable for commercial and industrial systems, as well as food processing and other applications with higher media and hygiene requirements. They work with different media and can meet sanitary standards. Carbon steel shunts are primarily used in simple heating systems that utilize clean water. Their application range is limited.
Service life With better materials and manufacturing processes, stainless steel models offer a service life of 15 years or more. They come with a 3-year warranty and show strong resistance to impact and leakage. Carbon steel models typically last only 5 to 8 years and carry a much higher risk of failure over time.
Maintenance and energy use Stainless steel requires less frequent maintenance, usually once every 3 to 6 months. There is no need for extra anti-corrosion treatment. The smooth inner surface also helps reduce energy consumption by 10% to 15%. Carbon steel often needs rust treatment every month. Maintenance costs are 3 to 5 times higher, and scaling inside the pipe increases energy loss.
Compliance and environmental impact Stainless steel products meet international certification requirements and are suitable for global export. They are also 100% recyclable. Carbon steel products face higher export risks. Short replacement cycles also lead to more waste and greater environmental impact.
6. What additional value can Plumberstar bring to Hydraulic Separator trade customers?
The long-term value becomes apparent over time, not just at the outset.
Cost optimization: The overall cost is well controlled. With a strong price-to-performance ratio and flexible trial policies, the initial investment is kept low. When it comes to batch orders, pricing remains competitive.
Compliance support: The full product range has passed safety certifications in multiple countries. All required customs and compliance documents are provided together, ensuring smooth clearance and reduced compliance risks.
Long-term service. Original spare parts are supplied for the full product life, and remote technical support is always available. This helps customers build local after-sales capability step by step.
Plumberstar also keeps long-term cooperation records with its partners. Product improvements are made based on real market feedback, which helps both sides grow and move forward together.
7. How does design flexibility help Hydraulic Separator system integrators?
Plumberstar offers full customization, from size and connection type to function and material. This makes it easier to match the real needs of different integration projects.
In HVAC hydraulic distribution systems, the shunt can be made with 1 to 12 branches, even with different branch diameters. Connection types support BSPP, BSPT, NPT, and other common thread standards. This allows for a direct connection to mainstream brands, such as Daikin and Gree, without requiring extra conversion parts.
For water purification system projects, the channel diameter and the filter mesh size can be adjusted based on actual demand. This helps match RO membrane modules with different flow rates.
Due to this flexible design, integrators do not need to add extra adapters because of the poor fit of standard parts. Pipeline resistance and leakage risk are reduced, and system commissioning becomes much easier and faster.
8. Why choose a factory-made stainless steel hydraulic separator?
Standard production and strict quality control
Plumberstar stainless steel hydraulic shunts are produced on automated lines. From raw material cutting and welding to surface polishing, every step follows ISO 9001 standards. Core dimensions are controlled within ±0.02 mm, which avoids the size variation often seen in manual workshop production. Quality control is done in three stages. Raw materials are checked by spectral analysis to confirm 304 or 316L composition. After welding, non-destructive testing is carried out. Finished units must pass a pressure test at 1.5 times the working pressure to make sure there are no sand holes and no leaks. Manual assembly products usually lack unified inspection standards. Weak welds and poor sealing are more common, and this creates higher operation and maintenance risks later on.
Optimized flow design for better system efficiency
The Plumberstar R&D team uses fluid simulation to optimize the internal flow path. A smooth, integrated channel design is used to lower flow resistance. Pressure loss is kept at or below 0.02 MPa, which is much lower than that of manually welded products. The factory-made shunt can also integrate flow sensors, temperature control valves, and other modules when needed. Interfaces follow common standards such as BSPP and NPT, so the unit can connect directly to building management systems for accurate hydraulic control.
Lower cost through scale, with flexible customization
Large-scale production allows Plumberstar to reduce raw material and manufacturing costs. Prices are typically 15% to 20% lower than hand-made products of the same specification. At the same time, customization remains flexible. Branch numbers can be set from 1 to 12.
