Continuous quantitative supply without air chamber! Diaphragm pump with no pulsation.

Continuous quantitative supply without air chamber! Diaphragm pump with no pulsation.

Achieve a continuous constant flow without pulsation, without using an air chamber! Measurement with a flow meter is possible!

The Smooth Flow Pump "BPL Series" is a diaphragm pump that achieves a continuous, pulsation-free flow without using an air chamber, allowing for measurement with a flow meter. It ensures uniformity in chemical injection and mixing, enabling consistent quality control. The power consumption is less than half that of air-driven or rotary pumps. 【Features】 ■ Achieves a continuous, pulsation-free flow. ■ No mechanical seals, preventing liquid leakage to the outside. ■ No need for an air chamber, eliminating piping vibrations due to air reduction and the risk of chemical splatter from potential air chamber damage. ■ The absence of pulsation allows for design with smaller, more cost-effective piping. ■ With a constant flow, it is possible to manage the amount of chemicals used with a flow meter. ■ Compared to conventional diaphragm pumps (300L/H class), CO2 emissions are reduced by approximately 50%. *For more details, please request documentation or view the PDF data available for download.

[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 stabilized 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. To suppress the pump's pulsation, an air chamber was installed in the piping. As a result, there were challenges such as "the need to frequently inspect the air chamber and replenish air" and "pulsation causing flow errors, which can lead to equipment shutdown." For solutions to these challenges, please download and view the PDF materials. 【Customer Challenges】 ■ The 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 ■ Pulsation can cause flow errors, which may lead to equipment shutdown *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 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 hydrochloric acid containing high-temperature metal powder, necessitating frequent diaphragm replacements." For solutions to these challenges, please download and refer to the PDF document. 【Customer's Challenges】 ■ The diaphragm quickly tears due to hydrochloric acid containing high-temperature metal powder, requiring frequent diaphragm replacements. ■ 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] Automation of the 4-liquid mixing process improves quality.

[Case Study] Automation of the 4-liquid mixing process improves quality.

Solving issues such as "variability in concentration"! A case where automation improved the process and 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 "operators having to constantly monitor the concentration in the stirring tank and manually adjust the four pumps." For solutions to these issues, please download and view the PDF document. [Customer's Issues] ■ Variations in concentration due to uneven stirring in the tank ■ Operators 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] Dividing the raw material liquid into six directions and injecting it into the mixing tank.

[Case Study] Dividing the raw material liquid into six directions and injecting it into the mixing tank.

We have resolved the request to inject the same amount of liquid from six locations at the top of the mixing tank in the manufacturing process of dental materials! Here is a case study from a dental materials manufacturer.

The dental materials manufacturer requested to inject the same amount of liquid from six locations at the top of the mixing tank during the manufacturing process of dental materials. However, there was a challenge in finding a manufacturer that could produce a six-channel diaphragm pump. Please download the PDF document to view the solution to the challenge and request. 【Customer's Challenge/Request】 ■ Unable to find a manufacturer that could produce a six-channel diaphragm pump. *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 can occur unknowingly due to corrosion from sulfuric acid" and "the need for pump overhauls every three years, incurring costs each time." Please download the PDF document to see the solutions to the challenges and requests. 【Customer's Challenges and Requests】 ■ An accumulator was installed to eliminate pulsation, but it can be damaged unknowingly due to corrosion from sulfuric acid. ■ Due to long-distance piping, a high-pressure pump is used considering 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 document 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

Control of stroke length is not performed! Introduction of a case where gas lock no longer occurs even in low flow regions.

The local government (sewage treatment plant) measured the flow rate of the water flowing through the channel after sedimentation and filtration, and injected the necessary amount of sodium hypochlorite. Using a diaphragm pump, they implemented dual control of stroke length and rotation speed; 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 entrainment) occur. *For more details, please refer to the PDF materials or feel free to contact us.
