- Easy to install and replace, minimizing system downtime
- Compact, collapsible design saves space and simplifies maintenance
- Durable construction withstands harsh chemical environments
- Enhances overall pump reliability to protect your system investment
How It Works
The collapsible roller head assembly is a critical component inside the chemical feed pump, responsible for compressing the tubing as it passes through the pump head. This compression creates a peristaltic action that accurately moves measured amounts of chemical solution through your water treatment system. The rollers rotate smoothly, reducing tubing fatigue and preventing leaks or dosing inconsistencies.
By maintaining optimal roller pressure and alignment, the STQP500-1 ensures consistent flow rates and precise chemical feed, which is vital for maintaining system balance and water quality in various industrial or municipal applications.
What to Expect
After installing the STQP500-1 Collapsible Roller Head Assembly, you will notice immediate improvements in pump operation, including quieter performance and smoother tubing movement. During the first few weeks, the assembly will settle into optimal function, helping maintain steady chemical dosing without fluctuations.
Over time, the durable materials and design reduce the need for frequent maintenance or roller head replacements, ensuring your chemical feed pump continues to operate efficiently and reliably for the long term.
What’s Inside
- Collapsible Roller Head Frame – Provides structural support while allowing easy access for tubing changes
- Precision-Machined Rollers – Ensure smooth, consistent compression and reduce tubing wear
