Atmospheric pressure values in various pressure units.

Atmospheric pressure values in various pressure units.

Introducing the basic knowledge of small DC diaphragm pumps (micro pumps)!

Regarding units of pressure, the new measurement system uses Pa (Pascal), N/m² (Newton per square meter), and bar as SI units, while Torr is recognized as a non-SI unit for pressure within the body, and mmHg (millimeters of mercury) is recognized for blood pressure. There are two methods for expressing vacuum pressure. The vacuum industry uses absolute pressure, while other industries often use gauge pressure, so when looking at documents or catalogs, it is necessary to check which method is used to express pressure. [Notation of Vacuum Pressure] 1. Absolute pressure with absolute vacuum as 0 (zero) - Often abbreviated with "a" or "abs" after the unit (often omitted) 2. Gauge pressure with atmospheric pressure as 0 (zero) - Often abbreviated with "G" or "Gauge" after the unit (often omitted) *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Stability of Concentration During Sulfuric Acid Dilution and Reduction of Work Costs

[Case Study] Stability of Concentration During Sulfuric Acid Dilution and Reduction of Work Costs

Solving issues such as 'unable to achieve the targeted concentration'! Examples of stable concentration and reduced operational costs.

In the process of diluting concentrated sulfuric acid with industrial water, a diaphragm pump is used. At a chemical manufacturer, an air chamber was installed on the piping to suppress the pump's pulsation. As a result, there were challenges such as the need to frequently inspect the air chamber and replenish air, and the occurrence of flow errors due to pulsation, which could cause the equipment to stop. For solutions to these challenges, please download and view the PDF materials. 【Customer Challenges】 ■ Need to frequently inspect the air chamber and replenish air ■ If air replenishment is neglected, pulsation occurs and liquid may relieve at abnormal pressure, preventing the injection of the specified amount of sulfuric acid and achieving the desired concentration ■ Flow errors may occur due to pulsation, which can cause the equipment to stop *For more details, please refer to the PDF materials or feel free to contact us.

[Case Study] Quantitative Transfer of Hydrochloric Acid at 98°C Containing Metal Powder

[Case Study] Quantitative Transfer of Hydrochloric Acid at 98°C Containing Metal Powder

Quantitative transfer of hydrochloric acid at 98℃! Solving issues such as "measurement values were unstable due to the pulsation of the pump"!

The request from the steel manufacturer was to send 98°C hydrochloric acid containing metal powder to a concentration analyzer in order to manage the concentration during the acid pickling process. However, due to the use of an air-driven diaphragm pump, there were challenges such as "the diaphragm quickly tearing due to the high-temperature hydrochloric acid containing metal powder, necessitating frequent diaphragm replacements." For solutions to these challenges, please download and view the PDF document. [Customer Challenges] ■ The diaphragm tears quickly due to the high-temperature hydrochloric acid containing metal powder, requiring frequent diaphragm replacements. ■ The measurement values were unstable due to the pulsation of the pump. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Automating the 4-liquid mixing process and improving quality.

[Case Study] Automating the 4-liquid mixing process and improving quality.

Solving issues such as 'variability in concentration'! A case where automation improved the process and enhanced quality.

The request from the steel manufacturer was to mix four types of liquids to apply a coating agent on the surface of electrical steel sheets and supply it to a roll coater. However, each liquid was transferred to a tank using a hydraulic diaphragm pump, and after stirring and mixing, it was supplied to the roll coater. As a result, there were issues such as "variations in concentration due to uneven stirring in the tank" and "the operator had to constantly monitor the concentration in the stirring tank and manually adjust the four pumps." For solutions to these issues, please download and refer to the PDF document. [Customer's Issues] ■ Variations in concentration due to uneven stirring in the tank ■ The operator must constantly monitor the concentration in the stirring tank and manually adjust the four pumps *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Safe Long-Distance Transport of Concentrated Sulfuric Acid (98%)

[Case Study] Safe Long-Distance Transport of Concentrated Sulfuric Acid (98%)

Solving issues such as 'damage caused by corrosion from sulfuric acid without realizing it'! Introducing a case study from a steel manufacturer.

The steel manufacturer was using a hydraulic diaphragm pump to transport 98% sulfuric acid over long distances within the steelworks. However, there were challenges such as "damage that may occur unknowingly due to corrosion from sulfuric acid" and "the need for pump overhauls every three years, incurring costs each time." For solutions to these challenges and requests, please download and view the PDF materials. 【Customer's Challenges and Requests】 ■ An accumulator was installed to eliminate pulsation, but it may be damaged unknowingly due to corrosion from sulfuric acid. ■ Due to long-distance piping, a high-pressure pump is used to account for pressure loss, and continuing operation without the accumulator functioning poses a risk of pipe damage, which is very dangerous. ■ Pump overhauls are required every three years, incurring costs each time. *For more details, please refer to the PDF materials or feel free to contact us.

[Case Study] Balancing Stable Operations During Normal Times and Measures Against Sudden Heavy Rainfall

[Case Study] Balancing Stable Operations During Normal Times and Measures Against Sudden Heavy Rainfall

No stroke length control! Introduction of a case where gas lock no longer occurs even in low flow ranges.

At the local government (sewage treatment plant), the flow rate of water flowing through the channel after sedimentation and filtration was measured, and the necessary amount of sodium hypochlorite was injected. Using a diaphragm pump, two types of control were implemented: stroke length control and rotational speed control. However, there was a problem where "when operating with a reduced stroke length during low processing volumes, injection failures due to gas lock occurred." For solutions to the issues and requests, please download and view the PDF materials. [Customer's Issues and Requests] ■ When operating with a reduced stroke length during low processing volumes, injection failures due to gas lock (air entrapment) occur. *For more details, please refer to the PDF materials or feel free to contact us.
