[Case Study] Pouring rust preventive oil in a surface treatment factory

Powerful self-priming ability and pumping capability!

●We want to reduce the amount of rust preventive oil. We received an inquiry from N.P. Company, a major surface treatment manufacturer, asking if there is a good pump for reducing the amount of rust preventive oil. The best method for use is to draw up the rust preventive oil and spray it with a gun nozzle, so we adopted the self-priming diaphragm pump model SN. When using a general-purpose pump with a gun nozzle to flow and stop the fluid, the problems that arise are: "the internal pressure continues to rise, causing blowout troubles from the piping" and "additional equipment like pressure switches becomes necessary, leading to high costs." ●With powerful self-priming and pumping capabilities, it can be used just by hanging it on the wall. The H2 SN model has a built-in relief valve, so even with frequent ON-OFF operations using the gun nozzle, it circulates within the pump and keeps the internal pressure below a certain level. The self-priming capability of the SN model is high, and this time it was delivered as a wall-mounted set, allowing fluid transfer using the gun nozzle simply by inserting the suction hose into the rust preventive oil. There are no initial costs for construction, and the person in charge commented, "If we were to try to do the same thing, it would normally cost 3 to 5 times more than H2's proposal."
