Self-priming diaphragm pump "SN Series"

Air operation and blockage operation OK! This is a transfer pump with a built-in relief valve that can be used for pressure delivery.

The "SN type" is a pump for chemicals that overcomes the weaknesses of conventional handheld pumps. It gently transfers liquids using a multi-diaphragm system, without stirring the liquid like handheld pumps do, and since there are no sliding parts such as mechanical seals, there is no contamination from wear and tear. 【Features】 ○ Can operate dry and under blockage ○ Built-in relief valve ○ Unique multi-diaphragm structure ○ Available in a wide range of options For more details, please contact us or download the catalog.

【Delivery Case】Zero risk of chemical splashes

It is possible to replenish the neutralizing agent without opening the tank lid!

●Refilling without opening the tank lid Typically, the addition of neutralizing agents such as caustic soda or sulfuric acid into the chemical tank of a pH automatic neutralization device was primarily done manually or with handheld insertion pumps. In recent years, due to an increased awareness of safety, more customers have requested "keyed" tank inlets. The issue that arises is the hassle of having to "unlock" each time chemicals are refilled. To address this, H2 has installed a self-priming diaphragm pump onto a PVC tank, with the discharge side piped to the tank, allowing the suction hose to be inserted into a polycan or pail, enabling refilling simply by turning on a switch. ●No dangerous chemicals splashing around! The advantage is that dangerous chemicals can be refilled without opening the keyed inlet. There is no longer a problem of where to store the handheld pump after use. Since the discharge side is piped, the risk of the "discharge hose coming off the tank and causing a large amount of chemicals to splash around," which could be alarming with a handheld pump, has been eliminated. This is a safety measure that was previously unimaginable with conventional self-priming pumps.

[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."
