Q: What is the difference between the stainless steel (F suffix) and standard CDLF pumps? What are their suitable applications?

A:

The core difference lies in the material of the wetted parts, which are suitable for different medium scenarios, and must be distinguished in global project selection:

Q: How to perform daily maintenance on CDLF vertical multistage centrifugal pumps? How to extend their service life?

A:

Following global industrial pump maintenance standards, following these 5 points can greatly extend the service life of the pump:

1.       Before startup: Prime the pump and vent air, never run dry, to avoid mechanical seal damage from dry grinding;

2.       Daily inspection: Check the pump's vibration, noise, and mechanical seal leakage daily. If there is continuous dripping, overhaul immediately;

3.       Motor maintenance: For F-class insulation motors, check heat dissipation regularly. For motors with lubrication nozzles, add high-temperature lithium-based grease every 3-6 months;

4.       Long-term shutdown maintenance: Drain all residual liquid in the pump, clean the pump body to prevent rust, and rotate the shaft once a month;
