In high-end manufacturing sectors such as semiconductors and perovskite photovoltaics, precision fluid control is critical. For years, Japanese brands like KOGANEI and IWAKI have dominated the market for high-precision metering pumps, especially in demanding processes such as photoresist coating.
However, relying heavily on imported equipment also comes with challenges—export restrictions, supply chain uncertainty, long lead times, and delayed after-sales support. These issues can directly impact production stability and limit capacity expansion for manufacturers.
So the question is: Can domestic alternatives truly replace imported metering pumps?
A Domestic Alternative: Guangzhou Ascend FSH-EBP Series
With nearly 20 years of experience in precision fluid control, Guangzhou Ascend has developed the FSH-EBP series high-precision metering pumps. These pumps are designed to match the performance of imported counterparts and offer a practical 1:1 replacement solution for production lines.
More importantly, they provide a more stable and controllable supply option for manufacturers operating in high-end industries.
Core Advantages of the FSH-EBP Series
1. High Precision for Nanoscale Processes
In semiconductor applications, even minor deviations can affect product quality. The FSH-EBP series is engineered to meet strict process requirements such as coating thickness control within ±5 nm.
Key capabilities include:
-
Discharge repeatability ≤ ±1% for consistent dosing
-
High resolution of 1 μL for precise micro-dispensing
-
Pulse-free delivery to ensure uniform fluid distribution
-
Stable pressure output to eliminate coating inconsistencies
These features help maintain uniformity across wafers and reduce process variability.
2. Flexible Adaptation to Different Fluids and Processes
Modern production lines require equipment that can handle a wide range of materials. The FSH-EBP series supports:
-
Viscosity range: 0–300 Cp
-
Flow rate: 0–10 mL/s
-
Single-shot volume: up to 30 mL
This makes it suitable for various media, including photoresist and perovskite slurry, across both R&D and mass production stages.
3. High Cleanliness and Chemical Resistance
For semiconductor-grade processes, contamination control is essential. The FSH-EBP series is optimized in both materials and structural design:
-
Wetted parts made of SUS316, PTFE, and PFA for chemical resistance
-
Smooth internal surfaces to minimize particle generation
-
Dead-zone-free chamber design to prevent residue buildup
These features ensure fluid purity and reduce the risk of defects during coating processes.
Typical Application Scenarios
Photoresist Precision Dispensing
The FSH-EBP pump accurately dispenses photoresist onto substrates. Combined with spin coating, it enables uniform thin-film formation, supporting subsequent lithography and etching processes.
Perovskite Solar Cell Production
For perovskite slurry—known for its viscosity and sensitivity—the system provides stable and consistent delivery. This helps improve coating quality and ultimately enhances cell efficiency.
Why Consider Domestic Replacement Over Imported Pumps?
Switching from imported brands to domestic solutions like the FSH-EBP series offers several practical benefits:
-
More reliable supply chain with reduced procurement risks
-
Shorter lead times and faster delivery
-
Lower overall cost (purchase + maintenance)
-
Better local service support, including on-site assistance
-
High compatibility with existing production lines (minimal modification required)
In addition, proven applications in leading domestic enterprises demonstrate the product’s stability and maturity in real production environments.
