Outstanding self-priming performance even under harsh conditions! Stable quality achieved through in-house integrated production from casting of special material products.
The "UHN Series" is a self-priming vortex pump that achieves a negative pressure of 60 to 90 kPa due to its internationally patented air-water separation mechanism, demonstrating outstanding self-priming capability. Its simple structure without an inlet check valve makes it robust and easy to maintain. Typically, there is no need to install a foot valve or intermediate valve on the suction side. To accommodate various liquid types, we offer a wide range of materials, including FC, SCS, and corrosion-resistant and wear-resistant materials such as Yokota special stainless cast steel (YST). 【Features】 ■ Outstanding self-priming capability ■ No issues even if air mixes during pumping ■ Low NPSH ■ Simple structure without an inlet valve, no foot valve required ■ Capable of overcoming hills and long suction piping *For more details, please refer to the PDF document or feel free to contact us.

Company information
Yokota is a water solutions company that creates unique products to solve various problems related to handling water and fluids through new patented theories and know-how. For example, in terms of pumps, they offer a wide range of pumps with features not found in conventional pumps, such as self-priming pumps that can draw in water mixed with air or slurry, and pumps that can de-bubble and degas in one go. Additionally, regarding valves, they have developed various types of valves with simple structures that function cleverly, such as non-slam check valves that do not cause water hammer and automatic control valves that can regulate flow, pressure, and water level using the power of water itself without electrical control. On the other hand, for the metals used in these products, they have independently developed seawater-resistant stainless steel that does not corrode in seawater, as well as other corrosion-resistant and wear-resistant stainless steel alloys, and they carry out consistent production from casting in-house to accommodate challenging liquid qualities. These products are utilized in a wide range of fields, including ultra-pure water production, agricultural irrigation, water treatment, seawater treatment, chemical liquid processing, and pollution prevention treatment.
