As the energy storage industry moves toward larger-scale production, electrolyte filling equipment needs to keep up with higher requirements for flow efficiency, metering consistency, operating stability, and compliance.
For manufacturers of large-format storage cells, containerised storage cells, and commercial & industrial storage batteries, the filling pump is an important part of the production process. A constant flow metering pump can help maintain stable electrolyte delivery while supporting higher production efficiency.
Why Is Constant Flow Important for Electrolyte Filling?
Electrolyte filling requires consistent fluid delivery. If the flow fluctuates or filling accuracy changes between cycles, it can affect batch consistency and overall production efficiency.
The FSH-CF150 Series Constant Flow Metering Pump is designed for high-flow electrolyte filling, with a filling rate of up to 120 g/s. This makes it suitable for mass-production scenarios where higher filling efficiency is required.
For a newly built production line, higher flow capacity can help reduce the number of pumps needed. For an existing line, upgrading the filling equipment can provide additional capacity without fundamentally changing the production process.
How Does the FSH-CF150 Series Maintain Stable Flow?
The FSH-CF150 Series uses a cam-driven constant flow structure to provide continuous, pulse-free fluid output.
Its fully enclosed pump chamber is designed to reduce problems such as electrolyte crystallisation and pump seizure. The pump also supports digital remote parameter adjustment, making it suitable for continuous production environments.
For energy storage manufacturers running intensive production schedules, stable equipment operation can help reduce unnecessary downtime and maintenance requirements.
What About Low-Temperature Electrolyte Filling?
Temperature can be an important factor in electrolyte filling because changes in electrolyte density can lead to filling volume deviations.
For production lines where low-temperature electrolyte filling is required, the -T variants of the FSH-CF150 Series add temperature sensing and compensation. The system monitors electrolyte temperature in real time and automatically compensates for filling deviations caused by temperature changes.
This helps improve filling consistency under low-temperature conditions and supports more stable batch production.
What About Explosion-Proof Requirements?
Energy storage battery production environments can have specific explosion-proof requirements, particularly for overseas projects.
The FSH-CF150 Series includes variants designed for different regional requirements. The FSH-CF150-EU-E is the ATEX-certified EU variant, while the FSH-CF150-NA-E is the UL-certified North American variant.
The series therefore provides different configurations for domestic production as well as EU and North American markets.
Six Configurations for Different Production Requirements
The FSH-CF150 Series includes six variants:
-
FSH-CF150-D-E: Standard domestic explosion-proof configuration without temperature compensation.
-
FSH-CF150-D-E-II: One controller operates two pumps to reduce controller footprint.
-
FSH-CF150-D-E-T: Temperature sensing and compensation for low-temperature electrolyte filling.
-
FSH-CF150-D-E-T-II: Temperature compensation configuration with one controller operating two pumps.
-
FSH-CF150-EU-E: ATEX-certified variant for EU-related applications.
-
FSH-CF150-NA-E: UL-certified variant for North American applications.
This configuration approach allows manufacturers to select a pump according to production conditions and regional compliance requirements rather than using a single configuration for every line.
A Practical Pumping Solution for Energy Storage Production
As energy storage battery manufacturing continues to scale, electrolyte filling equipment needs to balance production efficiency with stable metering and reliable operation.
With a flow rate of up to 120 g/s, constant-flow output, optional temperature compensation, and regional explosion-proof variants, the FSH-CF150 Series is designed to address several of the key requirements involved in high-volume electrolyte filling.
For manufacturers producing large-format storage cells, containerised storage cells, and C&I storage batteries, selecting the appropriate constant flow metering pump can be an important step toward more consistent and efficient electrolyte filling.
