● The existing pump stops operating We received a consultation from a certain cosmetics manufacturing factory. The submersible pump currently in use is not designed for high temperatures, so it stops immediately after starting, making it difficult to transfer hot water. Therefore, we adopted the H2 JCV series, which allows for stable transfer even at high temperatures of 80°C. ● The burden on operators has been eliminated! Previously, every time the pump stopped operating, the managers had to wait for the temperature to drop or pull it up to check the situation, which was a significant burden. Since switching to the heat-resistant submersible pump JCV series, it has continued to operate stably even at high temperatures, resulting in a reduced burden on the operators.

● Recovery of high-temperature water during konjac production The submersible pumps used by our customers until now were not designed for high temperatures, causing them to stop immediately after starting, making it difficult to recover high-temperature water. By adopting our JCV series, stable recovery is now possible even at high temperatures of 80°C. ● Selection of hygienic all-stainless steel (SUS316) float Given that the water is slightly alkaline and high-temperature, and considering it is for food factories, we have chosen hygienic all-stainless steel. Additionally, we supplied it with a high-temperature compatible float switch that automatically activates when the pit is full.

●I want to use the hot water from the Japanese kettle in a separate process. In the sake brewery, there is a vessel called "Koshiki," which is used for soaking rice and steaming it with steam generated from below. It plays an important role in the sake-making process. The Koshiki is placed on top of a Japanese kettle filled with boiling water for steaming. The hot water from that kettle can be reused in subsequent processes, but until now, the submersible pumps had a low heat resistance, often stopping during use. ●Heat-resistant submersible pumps are effective for hot water sterilization. By using the heat-resistant submersible pump JCV series, it has become easy to make effective use of hot water. (The photo above shows the JCV type heat-resistant submersible pump being placed into the Japanese kettle.) To avoid compromising the flavor, disinfection with detergents is not used, and in sake breweries where hot water sterilization is mainstream, the hot water from the Japanese kettle is used for hot water sterilization in various locations.

● Adopted by a major cosmetics factory with strict standards for quality control and factory equipment We received an inquiry regarding high-temperature water transfer from a certain major cosmetics manufacturing factory, and they adopted our heat-resistant water pump JCV series. Since it is a cosmetics manufacturing factory, the equipment used in the factory needed to meet strict standards, resulting in a total of three units being delivered. ● Flexible specifications The user's desired delivery time was very short, and it was also necessary to reduce the specifications due to the size of the pit. H2 is capable of responding flexibly to such customer requests. If you have any issues with fluid transfer, including high-temperature water transfer, please do not hesitate to contact us.

● Adopted for the transport of alkaline high-temperature wastewater We received an inquiry about high-temperature water transport from a major steelworks, and they chose our heat-resistant water pump, the JCV series. Due to the alkaline nature of the wastewater, it is made entirely of stainless steel, and it successfully cleared the silica-based SS concentration without any issues. Liquid specifications: pH 12.5, SS = 50 ppm (silica-based SS), liquid temperature 70°C ● Short delivery times for different voltages are also possible The request was for 440V three-phase, and we can accommodate it with the usual delivery time for all-stainless steel. While other companies' 440V pumps may take about three months for delivery, H2, which specializes in manufacturing heat-resistant water pumps, can ship in about half that time. If customers are struggling with poor delivery times when their pumps from other manufacturers fail, please feel free to consult us.

We have received a consultation from a major automotive parts manufacturer, Company S, stating that they are troubled by frequent failures of the submersible pump they have been using until now. The current submersible pump is unsuitable for both temperature (80 degrees) and corrosion resistance, so they have adopted our heat-resistant submersible pump (made entirely of stainless steel). The liquid used is bonding liquid (zinc phosphate) which is high-temperature and contains slurry. The pump was installed underwater with the aim of transferring from the second floor to the third floor. [Reasons for Adoption] ■ Extensive track record as a heat-resistant submersible pump (adopted by other major automotive parts manufacturers) ■ Flexible response as a manufacturer to special specifications ■ Short delivery time ■ Low price *For more details, please refer to the PDF document or feel free to contact us.

● The gear pump breaks down quickly, causing trouble We received a consultation from Company J, a major steel manufacturer, stating, "The gear pump breaks down quickly, and we are in trouble." Upon checking the fluid, we found that they were transferring high-temperature (90°C) high-viscosity oil with the gear pump. Additionally, they mentioned that a small amount of slurry (iron powder) inevitably mixes in, leading us to conclude that the slurry was causing the gear pump to fail. We proposed the air diaphragm pump model ADD, and after they used a demo unit, they decided to adopt it. ● High-temperature fluid + slurry + high-viscosity compatibility The features of the diaphragm pump include "self-priming," "pressure delivery," and "capability to transfer slurry and viscous liquids." Our company has further developed technology from heat-resistant pumps to also apply to diaphragm pumps, enabling them to handle high-temperature fluids. There are not many pumps that can meet such harsh conditions. Generally, gear pumps, which are said to be suitable for transferring high-viscosity oils, often struggle with slurry. We received positive evaluations for meeting the conditions while also being cost-effective. Customers experiencing frequent gear pump failures are encouraged to consider this option.

●Cooling 100℃ boric acid and aluminum phosphate-containing water and transferring it with a submersible pump We received an inquiry from a wood processing manufacturing company in Fukuoka Prefecture, stating, "We would like to transfer a chemical fluid containing boric acid and aluminum phosphate at 100℃ from a drum using a submersible pump." The concentrations were each below 20%, but we proposed the JCVH type, which has high corrosion resistance due to its epoxy coating, considering both temperature and corrosion resistance. ●Cooling from 100℃ to 95℃ for transfer! The heat-resistant submersible pump JCVH type has a heat resistance temperature of 95℃, so they were satisfied with the operation of lowering the 100℃ hot water to 95℃ for use. We received feedback that they have been able to transfer without any issues after the installation.

●Transporting 95℃ boiler wastewater with a heat-resistant submersible pump We received an inquiry from a trading company in Shizuoka Prefecture, stating, "We would like to transport 95℃ weak alkaline boiler wastewater." We proposed the JCVH type submersible pump, which has a proven track record for handling boiler wastewater at 95℃. They appreciated its reliability and ease of use, leading to its adoption. After implementation, the feedback was positive, and they quickly placed a repeat order for another unit, resulting in a highly satisfactory case.

●Is there any way to deal with the frequently breaking pump? Due to various circumstances, the drain from the jacket of the reaction vessel could not be directly laid to the drainage ditch. Instead, it was first collected in a drainage pit and then pumped out to the drainage ditch using a submersible pump. Considering the possibility of the submersible pump breaking, we were using it while flowing cooling water, but the pump frequently broke due to heat. Therefore, we considered the JCVH-40 model, which can handle temperatures up to 95°C, and it was adopted with a float specification.

A waste disposal company in Saitama Prefecture consulted us about wanting to transfer high-temperature water discharged during the cleaning process using a submersible pump. Since the temperature was 80°C, we proposed the JCV type submersible pump with a float for ease of use. After several months of operation, they confirmed that there were no issues with transferring the high-temperature water, and they placed a repeat order for another unit to be used at a different site. The submersible pump that frees users from concerns about the dangers, cavitation, and installation hassles associated with transferring high-temperature water has received positive feedback. If there is no installation space in the tank, we can also propose a heat-resistant surface pump. [Case Study] ■ Delivery: Waste disposal company in Saitama Prefecture ■ Application: Transfer of 80°C high-temperature cleaning water ■ Model: JCV-7-50-A *For more details, please refer to the PDF document or feel free to contact us.

A food factory in Saitama Prefecture has ordered neutralization treatment equipment for boiler drainage and wastewater treatment in the food manufacturing process. The JCVH-40-A was adopted for transferring to the neutralization tank. Since the temperature was up to 95°C, we selected the JCVH type submersible pump with a float for ease of use and heat resistance. The wastewater flows into a temporary grease trap, so it was necessary to transfer it from there to the neutralization tank. However, the JCVH type submersible pump is designed to be compact, allowing for easy installation without issues. Even when the water level is low, the float height can be finely adjusted, allowing for customizable ON-OFF range. Additionally, while the pH of the wastewater may lean towards acidic or alkaline, the JCVH is fully covered with epoxy coating, ensuring chemical resistance. [Case Study] ■ Delivery: Food factory in Saitama Prefecture ■ Application: Transfer of boiler drainage flowing into the grease trap ■ Model: JCVH-40-A *For more details, please refer to the PDF document or feel free to contact us.

We received an inquiry from a recycling-related factory in a certain location in Aomori Prefecture. The temperature of the transfer water is 80°C, while the existing pump was rated for a maximum temperature of 60°C. Therefore, we selected and delivered the heat-resistant submersible pump JCVH-40 (rated for 95°C). Although it was said that the existing pump deteriorated quickly, we received positive feedback that the operation of the JCVH model is going well. By using the appropriate pump, it is possible to slow down the rate of deterioration. If you are having trouble with fluid transfer or would like to make improvements, please feel free to consult us. 【Case Study】 ■ Delivery: A certain location in Aomori Prefecture ■ Application: Transfer of hot water from cooling water tank ■ Model: JCVH-40 *For more details, please refer to the PDF document or feel free to contact us.

We received a request from a certain manufacturer in Tokyo stating, "We are looking for a compact heat-resistant submersible pump," and we proposed and were adopted for the JCVH-40 model, which can withstand temperatures of up to 95°C. The application was for constructing a recycling system for wastewater discharged from high-temperature industrial washing machines. The wastewater had a high alkalinity with a pH of about 10.5, containing detergents, but the JCVH was able to handle it. Additionally, the compact size of the JCVH made it a perfect fit for integration into the equipment. The heat-resistant submersible pump JCVH-40 has a space-saving design that can be installed in an area of approximately 300×200. It can also handle a certain level of chemical liquids, making it user-friendly. We also offer models with floats, so customers considering automatic control are encouraged to consult with us.

We received an inquiry from a major cosmetics manufacturing plant regarding heat-resistant submersible pumps to be used in a newly established drainage intermediate tank. We also proposed a detachable device, and they adopted two units of "JCV-22-50." Additionally, since they requested water level control, we suggested a heat-resistant float, which was also accepted. They requested a short delivery time (two weeks after order), and upon inquiring about the situation, they mentioned, "Initially, we were proceeding with another company's product, but only the control panel's delivery was on schedule, and we just found out that the pump would not be delivered in time." Therefore, while our standard delivery time is one month after order, we shortened it to two weeks. We also provided advice on compatibility with other companies' control panels, and together with the timely delivery, we were able to meet their satisfaction. Customers considering heat-resistant submersible pumps are encouraged to contact us. [Case Study] ■ Delivery: Major cosmetics manufacturing plant ■ Application: Transfer of high-temperature water from drainage intermediate tank ■ Model: JCV-22-80 x 2 units (with detachable device) * For more details, please refer to the PDF document or feel free to contact us.

We received a request from a major food company looking for a "heat-resistant submersible pump" that can be used with hot water up to 70°C. They were also concerned about corrosion resistance to alkaline substances, as it would be used for draining CIP alkaline detergents and cleaning water, so we proposed a heat-resistant submersible pump made of SUS316. It was also the perfect size for their pit dimensions. When we asked what influenced their decision, they mentioned that our delivery time (one month) was shorter compared to other manufacturers, and we also had a price advantage. Our heat-resistant submersible pump has a "standard specification" that is heat-resistant, making it excellent in terms of speed and cost.
