Do not use hardened steel, carbon fiber, glass fiber containing Caution materials, carbon materials. Those materials can drastically shorten your pump service-life. Do not use film or resin coating materials. Those materials can Caution lead to poor filter performance and Turbulence filter clogging. Do not operate the pump in a fluid containing a large amount of Caution grindstones or abrasive grains.
Suction Performance ES is self-priming pump. However, resistance in inlet line or air entry can reduce the suction capability of the pump. Always pay attention to the coolant surface level and clogging in inlet port (Perforated sheet metals). Make sure that there is no excess resistance in outlet line. It will Caution affect the pump suction performance.
