It was installed for the drainage of experimental wastewater in research facilities where quietness and space-saving are required.
A pharmaceutical manufacturer’s laboratory has newly moved into the building as a tenant, and numerous experimental devices have been installed. Due to the inability to achieve proper drainage gradients and the limited space within the laboratory, an immediate drainage system was installed for the experimental sink and fume hood. By placing it under the sink, we were able to secure space for researchers, and the quiet operation and low vibration were also appreciated, leading to customer satisfaction. For the drainage of the most critical equipment, a dual alternating operation system has been adopted.

Case study presentation! Achieving "visualization" of experimental wastewater! Contributing to the reduction of installation costs as well.
In June 2012, with the revision of the Water Pollution Prevention Act, "visualization" of wastewater discharge facilities for experiments and similar activities has become a requirement. The best solution for the "visualization" of such wastewater discharge facilities is the 'Sokuhai-kun 2'! Unlike the conventional gravity flow method, it connects the discharge pipe from the equipment directly to a pump, assisting in the "visualization" of the wastewater discharge facilities through pump-up discharge. By pumping up the wastewater, we can achieve the "visualization" of the discharge facilities. We are currently offering a collection of installation examples for free! 【Features】 ■ Tankless design with a compact, space-saving pump ■ Models available that support 100V power supply (for lift heights of around 4m) ■ Start and stop using a non-contact method based on air pressure detection ■ Can be installed in a short period of time *The collection of examples can be viewed immediately from the "Catalog Download" section. Please feel free to contact us.
Changed the drainage of 57 facilities to a pressurized pumping system! Connected to each experimental facility and routed through overhead piping to the treatment tank.
We have achieved "visualization" that complies with the "Water Pollution Prevention Act" by directly connecting the drainage equipment that previously used buried pipes or submersible pumps to the experimental device or drainage pipe with the Sokuhaikun 2, allowing for pressurized drainage. Since the pump can be installed close to the equipment, it starts operating immediately when inflow occurs and stops when inflow ends, eliminating the need for a drainage pit and making visual inspections and responses to potential leaks much easier. 【Features】 ■ No need for a drainage pit ■ The pump is made of cast iron, making it robust and quiet ■ Being tankless, there is almost no foul odor from stagnant water ■ Highly reliable automatic operation with a dedicated control panel and pneumatic switch ■ Can be installed in a short period and at low cost *For more details, please contact us or download the catalog to view.
Case study of the introduction of "visualization" of research wastewater under the Revised Water Quality Pollution Prevention Act!
The "Water Quality Pollution Prevention Act" has been amended to require the visualization of wastewater treatment systems mixed with chemicals to prevent the leakage of harmful substances. The "Sokuhai-kun II" is a compact immediate discharge pump that has been introduced for the visualization of research wastewater discharge systems. (Note: Research wastewater refers to rinse water from experimental equipment after the 3rd or 4th use.) By pumping up the wastewater from the research wastewater sink, we have renovated the system from a natural flow underground buried drainage pipe method to an overhead piping method, achieving the "visualization" of the wastewater treatment system. We also offer regular maintenance contracts. 【Features】 ■ Pumping up research wastewater for "visualization" ■ Regular maintenance contracts are also available *For more details, please refer to the PDF document or feel free to contact us.
