What causes superficial damage to rotating components in a KRAL K Series Water Pump?
If lack of lubrication or foreign bodies have caused superficial damage to rotating pump components in your KRAL Water Pump, check the screw set and the casing and replace if necessary.
How to prevent seal overload during heating of a KRAL Water Pump?
To prevent seal overload during the heating process of your KRAL Water Pump, open the pressure- or suction-side shut-off devices to prevent thermal expansion of the media causing a build-up of pressure.
What causes seal overload when a KRAL K Series Water Pump is at a standstill?
If a leaking return valve is causing seal overload when your KRAL Water Pump is at a standstill, clean the return valve and replace it if necessary.
What to do if high differential pressure overloads the sleeve bearing in a KRAL K Series?
If the differential pressure is too high and has overloaded the sleeve bearing in your KRAL Water Pump: 1. Dismantle the pump and clean it. 2. Smooth the superficial damage to the casing and the rotating parts with an oilstone and if necessary, replace the screw set and/or the casing. 3. Reduce the differential pressure.
What to do if low viscosity overloads the sleeve bearing in a KRAL K Series?
If the viscosity is too low and has overloaded the sleeve bearing in your KRAL Water Pump: 1. Dismantle the pump and clean it. 2. Smooth the superficial damage to the casing and the rotating parts with an oilstone and if necessary, replace the set of screws and/or the casing. 3. Increase the viscosity, for example by reducing the operating temperature.
