Salt brine pump

[mecoman]

Hello,

Any insight to a GrundFos 1-3/8" shaft centrif. salt brine pump. Leaking a few quarts a day. Using a single face ceramic/carbon internal mount with single spring seal. Liquid temp. 18 to 23 F, rpm on the tip of my tongue.

Let me know if more information is needed.

Thanks for your input.

Best Regards,
MECOMAN

If you have a single seal on Brine then you will have crystal formation on the atmospheric side of the seal as the mechanical seal leaks. This can be abrasive and wear the carbon face leading to excessive leakage. Normally I would recommend an intermitent water quench to wash away any crystal build up and use two hard faces such as Silicon Carbide vs Silicon Carbide faces.

1 Try washing away any crystal buil up with a water hose and see if the seal takes up.
2 If you replace the seal check the carbon face for damage, you should see grooving due to the solids coming across the face.
3 Change face materials.
