●I want to transport different types of liquids with one pump! We received an inquiry from Company T in the Kanto region, stating, "We want to transfer curing agent A and liquid B with one pump." The chemicals need to be mixed in equal amounts, with water glass and curing agent, and it was necessary to ensure corrosion resistance, pressure, and accurate dosing. By welding the connector on the suction and discharge sides of the photo department to seal it, we changed the structure so that the fluid drawn in from one side of the head is discharged alone without merging. ●A site that needed two pumps can now operate with just one! A site that previously used two pumps for transfer can now operate with one, achieving cost reduction and space-saving. There have been no issues due to the single-sided head design, and it is operating smoothly.

●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.

●We want to recover floating oil from high-temperature wastewater in a narrow pit. Until now, workers have been recovering oil from the high-temperature wastewater accumulating in the pit using tools like a "hishaku" (a ladle). Due to the high temperature and the dangers of working above the pit, they were troubled about how to recover the floating oil. Therefore, H2 proposed a combination of the ADD type air diaphragm for high temperatures and a custom-made recovery float. This was accepted after a satisfactory demonstration on-site. ●The float was manufactured to fit the pit, made entirely of SUS316 material. We determined the float size to fit the narrow pit, and since it would be exposed to corrosive liquids and high temperatures, it was constructed entirely of SUS316. The processing of the funnel part of the float was particularly challenging, but we completed it without issues. H2 offers the "H-FR" series of pump skimmers, but if the size does not fit or if material considerations are necessary, we can flexibly accommodate custom requests. We have a wealth of experience, so if you are struggling with floating oil or debris, please feel free to contact us.

●Drainage from the underground tank to the above-ground tank. Alarm system also ordered. We received an order for a drainage system, including polyethylene tanks, from an industrial equipment manufacturing factory. The drainage accumulating in the underground pit is detected by a level sensor, pumped up, and stored in the above-ground tank (6000L). When the drainage in the above-ground tank accumulates, an alarm sounds from the control panel installed in the clean room. We manufactured and constructed this system. In particular, the control panel is a crucial part of the drainage treatment system that affects the usability for the administrator. We conducted thorough meetings before production, resulting in a plant construction that achieved high user satisfaction. ●You can also trust us with tank installation and plant systems. H2 is not only a pump manufacturer but also specializes in equipment and plants. For this project, we were entrusted not only with the tanks but also with the installation and the system, including the control panel. By entrusting us with everything as a package, we can grasp the entire system, allowing us to propose low-cost solutions that meet user needs. If you are wondering, "Where should I ask for help?" please feel free to leave it to H2.

● Increased treatment volume of dialysis wastewater and replacement of neutralization treatment equipment We received an inquiry from a clinic in the Kansai region regarding the update of neutralization equipment due to the increase in dialysis wastewater treatment volume. The existing system was a neutralization treatment device from Company T, but due to a greater emphasis on responsiveness rather than price advantages, they decided to consider and place an order for our replacement. Since the site had limited space, it was necessary to devise a solution, such as splitting the raw water tank into two, to neutralize the increased treatment volume. ● Installation of neutralization equipment that meets treatment volume requirements in limited space The neutralization was done on both the alkaline side with caustic soda and the acidic side with dilute sulfuric acid, using our company's chemical injection pump. Thanks to its stable performance, it was operated with just one unit, eliminating the need for a backup machine. Additionally, the control panel size was compacted to about half of the conventional size, contributing to space-saving. The transfer from the raw water was also done using a submersible pump instead of a land pump, further saving space. Maintenance space was adequately provided, taking into consideration future electrode calibration and regular maintenance handling.

●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.

We received a request for a temporary receiving tank for wastewater containing oxalic acid and received an order from a major semiconductor manufacturing factory. Since it is wastewater containing oxalic acid, we confirmed corrosion resistance and finalized the nozzle layout after several on-site meetings. H2, as a pump manufacturer, is also skilled in equipment and plant work, and although the work took place in a clean room, we accepted the order from tank delivery and installation to piping construction. *For more details, please refer to the PDF document or feel free to contact us.

Even for custom products (PVC processed items), H2 quickly and affordably designs and manufactures high-quality products! We processed slits to allow for the insertion and fixation of aluminum plates inside the tank, rather than just a simple storage tank. The material of the tank is the most important selection point for corrosion resistance, but in this case, a proposal using PVC (or PVDF) is better due to its high processing flexibility. To fit into the limited space, we repeatedly discussed the shape and size before receiving the order. Customers who have been turned away by other companies or are not satisfied with the price or service are welcome to consult with us!

We received an order and delivered a filtration system for industrial water for a certain association. The existing filter was made of iron and painted, and due to aging, it frequently caused water leaks. The new system was designed to be made entirely of stainless steel, making the removal and installation process easier. We also took on the removal and disposal of the existing filter, as well as the extraction and filling of the filtering material by a local vacuum service. While the piping work was handled by a local contractor, our company's flexibility in on-site installation and construction is one of our strengths.

We received an inquiry from a car parts factory in Aichi Prefecture regarding the removal of sludge that occurs in bonding liquid. The amount of sludge was 1 to 2 bags (1t to 2t) per month, but they wanted to do this without incurring running costs, so we proposed the "Edge Wire Filter." This method has a proven track record in the carbon prevention process of another car parts factory, using a self-backwashing specification, and was adopted after several tests.

We received an order for the complete pH neutralization treatment, including construction, from a major ready-mixed concrete factory in the Shinshu area due to an increase in processing volume. Since it is alkaline wastewater, only the acid side (sulfuric acid) was controlled. The raw water had a pH of 12, and the processing volume was 3m³/h, but it was designed compactly. We undertook the local construction, and all installation, electrical work, and piping were completed by our company. Along with cost advantages, our numerous achievements and the ability to complete the entire construction process are our company's strengths. [Case Study] ■ Delivery: Major ready-mixed concrete factory in the Shinshu area ■ Application: Neutralization treatment of alkaline wastewater ■ Model: Neutralization treatment plant *For more details, please refer to the PDF document or feel free to contact us.

We received a request from a wood processing factory in Gifu Prefecture for the transfer of a high-viscosity liquid (adhesive). Although it had a viscosity of 50,000 CP, our company conducted tests and confirmed that the transfer could be done using a drop-in method (where the fluid is above the pump and flows in naturally), leading to the decision to proceed with the implementation. After conducting a lab test with the actual liquid, you can determine whether the transfer is feasible, so if you have concerns like "Can this liquid be transferred?" please consult with H2 first!

We design and manufacture various custom devices for handling AdBlue, including self-weight drop hoses and pumps. We received an order for a testing device to evaluate the durability of urea water tanks (made of resin) intended for passenger vehicles from an automotive parts manufacturer. The successful delivery of a custom dispenser to an automobile manufacturer was a key factor in our adoption. Since refilling at gas stations is anticipated, we produced the device to allow testing with nozzles from Tatsuno, ELAFLEX (Germany), and PIUSI. Additionally, we implemented control for the discharge amount using feedback and feedforward for each nozzle.

A major automotive parts manufacturer consulted us during the design of a new complete recycling system for bonding liquid (zinc phosphate) wash water. Based on our extensive experience with bonding liquid, we proposed a filtration system. "The filtering is done on the pump suction side, preventing sludge from flowing into the pump and reducing troubles." "A dual system allows one unit to operate while the other is being cleaned." "The adoption of the optimal filter," among other factors, was appreciated, and due to our prior transactions involving pumps and filters, our proposal was accepted. [Case Study] ■ Delivery: Automotive parts manufacturer O Company ■ Application: Sludge filtration of bonding wash water ■ Model: Bag filter housing (SUS) + filter, a total of 2 units *For more details, please refer to the PDF document or feel free to contact us.
