The safety and durability of factories are, of course, important points. For example, in the wastewater treatment of chemical plants and the pulp bleaching process in paper mills, magnesium hydroxide slurry (a liquid containing magnesium hydroxide) is used. However, the pumps that transport this magnesium hydroxide slurry often face challenges regarding safety and durability. This time, we will introduce a case of a greedy improvement that can solve these two issues at once. *For more details on the column, please refer to the related link.

Saburo: "Hey, Pump Man. I'm on summer vacation right now, but even when we're resting, the pump is still working, right? Does the pump not get a break?" Mitsuwa Man: "I see. That's an interesting question. Actually, the industrial pumps we make are the perfect example of working around the clock, 24 hours a day, 365 days a year." Saburo: "So even when I'm sleeping at night, the pump is always working, which means it doesn't get a break like I do." *For more details on the column, please refer to the related links.

Saburo: Mitsuwa Man, I went on a trip by Shinkansen the other day! Mitsuwa Man: That’s great! The Shinkansen is an amazing machine made by combining various technologies. It’s surprising how fast it can go. Saburo: Yeah, it was really fast! But the Shinkansen and a pump, they’re not really related, right? Mitsuwa Man: Good question. Both the Shinkansen and a pump have a common role of transporting something from point A to point B. For example, the Shinkansen carries people and luggage, while a pump moves liquids and gases. So, in that sense, even though they are machines from different fields, you could say they share a common role. *For more details, you can view the related links.

Saburo: "Hey, Pump Man. Recently, things like air conditioners, TVs, and electricity can be controlled via WiFi, right? What about pumps?" Mitsuwa Man: "That's the talk about IoT, the Internet of Things. We pumps are still not fully connected to the internet, but the number of IoT sensors for monitoring pump conditions is increasing." Saburo: "I see. What kind of things, for example?" Mitsuwa Man: "What is commonly used for pumps are vibration sensors. When a pump starts to fail, it often generates vibrations, so these sensors are designed to detect that." *For more detailed information, you can view it through the related links.

In electronic semiconductor factories and plating factories, inorganic wastewater treatment facilities are widely used. In many cases, the raw wastewater for this equipment is often acidic, and slurries of calcium hydroxide or magnesium hydroxide are used to neutralize it. Stainless steel land pumps are commonly used in the process of transferring these neutralizing agents, but there are cases where these stainless steel pumps can encounter corrosion issues. This time, we will introduce this problem and one of the solutions. *For more detailed information, please refer to the related links. Feel free to contact us for more details.

Saburo: Hey Mitsuwa Man, how does a pump work? Mitsuwa Man: Good question, Saburo-kun. A pump is a machine that moves liquids, and it often uses motors, air, or engines to operate. Saburo: I see! So with a motor, how does it actually make the pump work? The motor is that rotating thing, right? Mitsuwa Man: That's right. A motor is a device that converts electrical energy into mechanical energy, and it works by rotating something called a shaft. This rotational force is transmitted to the pump using belts or chains, similar to rubber. Therefore, many pumps use this rotational force to spin blades like those in a fan, adding power to the water. *For more detailed information, you can view it through the related links.

Mitsuwa Man: Saburo-kun, EVs have been a hot topic lately, do you know about them? Saburo: Of course I know! They're electric vehicles, right? They seem good for the environment and look cool too! Mitsuwa Man: That's right. Cars that run only on electricity without using gasoline are called EVs. Saburo: But electricity seems like it would run out quickly. My remote control car runs out of batteries really fast when I play with it. Mitsuwa Man: That's true. So, the distance that an EV can travel on a single charge is often shorter than that of gasoline cars. *For more details, you can view the related links.

Saburo: My pencil can't write again. Sharpening it is such a hassle. Mitsuwa Man: That's because the pencil lead is worn down. Saburo: Then why not make it harder so it doesn't wear down? Mitsuwa Man: I can see why you'd think that. But pencil lead is made of graphite and clay, and it gets gradually worn down and sticks to the paper, allowing you to write letters and draw pictures. So if the lead is too hard and doesn't wear down much, you won't be able to write or draw. It can't be too soft or too hard; finding that balance is important. *For more detailed information, please refer to the related links. Feel free to contact us for more details.*

At a certain automobile factory, the polishing liquid transfer pump that came with the liquid honing device was maintained every 3 months to 1 year. This pump is a cyclone pump, and frequent maintenance was required due to damage to the impeller lining and wear of the seal ring and sleeve. With a high frequency of maintenance, continuous costs and effort can accumulate without notice. Therefore, Mitsuwa Pump proposed the "Clover Pump," a rubber-lined pump with a proven track record as a transfer pump for polishing liquids and ceramic slurries. *For more detailed information, please refer to the related links.

Saburo: It's so cold! Pump Man, it's been getting colder lately. Mitsuwa Man: Yeah, it’s especially cold today. Do you have a hose at Ichiro-kun's house that you use for watering the garden? Saburo: Yes, I do. Why? Mitsuwa Man: On cold days like today, if there's water left in the hose, it can freeze and cause the hose to burst, or you might not be able to use it until the ice melts. So, it's better to be careful and make sure as little water as possible is left in the hose. *For more details, please refer to the related links. For further inquiries, feel free to contact us.*

Liquids containing strong acids or strong alkalis cannot be discharged as they are due to concerns about environmental degradation. Such waste liquids need to be cleaned to a level that does not pose a problem to the environment. The important work of handling this is done by industrial waste disposal companies and recycling firms. They perform this crucial task every day to prevent environmental degradation. Moreover, safely and efficiently transporting such liquids is also a challenging task. *For more detailed information, please refer to the related links. Feel free to contact us for more details.*

An essential facility in many factories is wastewater treatment. This wastewater treatment equipment receives liquids containing various components and different solids. To transport such a diverse range of liquids, slurry pumps are indispensable. Due to the various cases in which slurry pumps are used, they require more maintenance compared to general-purpose pumps that transport clean water. One of the common causes of this maintenance is liquid leakage. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*
