There is also a self-priming type with a vertical and horizontal split design! Stable operation is possible even within a high head usage range!
The "HD type" is a dual-suction volute pump that operates efficiently over a wide range of pumping volumes, has a low NPSHR, and can maintain stable operation up to high head usage ranges. The casing is designed with a horizontal split at the top and bottom, allowing for internal inspection of the pump by simply removing the upper cover without disassembling the piping or bearings. By linking a unique air separation mechanism (patented) with the pump, it can self-prime even with suction piping that has a mountain-shaped configuration exceeding the dam, enabling automatic pumping operation. 【Features】 ■ Wide operating range ■ Easy maintenance ■ Abundant material options ■ Self-priming with linked air extraction (optional specification) *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 de-gas 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.
