The "SAH-L type" is a horizontal submersible axial flow pump capable of operating at ultra-low water levels. Air intake from the water surface can cause noise, vibration, and surging in the pump. The SAH-L type employs a rectifying plate that effectively prevents the generation of air vortices that lead to air intake, enabling operation at ultra-low water levels. The pump can be easily attached and detached simply by raising and lowering it along the guide pipe. You can consider pump station equipment that can be selected according to local conditions. 【Features】 ■ Ultra-low water level operation (the pump can operate at a water level up to 0.8 times the diameter) ■ Lightweight design ■ Adopts an automatic connection method that excels in workability ■ Can be attached and detached just by raising and lowering the pump along the guide pipe ■ Pump diameters range from φ400mm *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our equipment submersible pump, the 'A・C Series'. The cable entry uses a core wire seal, which prevents water from entering the motor chamber even if the cable sheath is damaged or the cable tip comes into contact with water, by shutting out water that travels along the core wire. The shaft seal section prevents water from entering the motor chamber with a double mechanical seal made of highly wear-resistant material. Additionally, an oil seal is used in conjunction to extend the lifespan of the mechanical seal (some models are excluded). 【Lineup】 ■ Vortex Type - Achieves high head with low power output ■ Non-Clog Type - Suitable for a wide range from small to large flow rates and high to low heads ■ Vortex Type (Vortex) - Although the pump efficiency is relatively low, it excels in passing through debris ■ Screw Type - Good passage for debris and suitable for transporting high-concentration sludge due to the screw effect ■ Built-in Chopper Mechanism Type (with foreign object crushing mechanism) - Incorporates a mechanism to prevent clogging and entanglement of debris *For more details, please refer to the PDF document or feel free to contact us.

Products born from Ni36×3DP aim for adoption in various fields. On October 27, 2020 (Tuesday), at the 64th Space Science and Technology Union Lecture, we gave a presentation on "Application of Metal Additive Manufacturing Technology to Low Thermal Expansion Materials" (LEX×3DP products). In the case of small machined parts, cutting costs can be reduced compared to current machined products. By manufacturing parts as a single unit, costs for processes such as welding and crimping can also be reduced. *For more details, please refer to the PDF materials or feel free to contact us.
