How It Works
The STUCFC5AD main shaft functions as a critical mechanical component within Stenner Series 45 and 85 chemical feed pumps. It transmits rotational force from the pump motor to the diaphragm or piston, enabling precise chemical dosing. By maintaining smooth shaft rotation, it ensures consistent chemical flow rates essential for effective water treatment.
Over time, shafts can wear due to continuous exposure to chemicals and mechanical stress. Replacing the shaft with this high-quality part restores the pump’s operational integrity and prevents potential leaks or dosing inaccuracies caused by shaft damage or misalignment.
What to Expect
After installing the STUCFC5AD main shaft, you will notice improved pump responsiveness and quieter operation. In the first few days, the pump should achieve more consistent chemical dosing without the fluctuations caused by worn components.
With regular maintenance, this replacement shaft will support long-term pump reliability, reducing the frequency of unexpected downtime and helping you maintain optimal water treatment system performance.
What’s Inside
- Main Shaft – precision-engineered to withstand chemical exposure and mechanical stress, ensuring long-lasting pump operation
- Durable Bearing Surface – reduces friction and wear, contributing to smooth rotational movement
- Seal Interface – designed to maintain a tight seal within the pump assembly, preventing leaks and contamination
How to Use
- Turn off the chemical feed pump and disconnect power supply for safety.
