Pump supply and tank agitation in one component!
The PTM pump mixer is an innovative system that performs mixing (stirring) inside a tank provided by the customer and transfers the contents to another location using a single component. The stirring utilizes the discharge jet of the pump. The pump is based on our magnetic levitation bearingless pump system, which has no bearings that could wear out and does not use shaft seals that could lead to liquid leakage, making it a groundbreaking non-contact pump and mixer. Based on the principle of magnetic levitation, the pump impeller floats non-contact within a sealed casing and is driven by the rotating magnetic field of the motor. Both the impeller and the casing are made of high-purity fluororesin with high chemical resistance. These, along with the rotor magnets, constitute the pump head.

High-temperature fluids + slurries + high viscosity support! Moreover, it's inexpensive!
● 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.
Achieving quantitative injection even under severe conditions!
●For the precise injection of small amounts of neutralizing agent (caustic soda). We received an order for a pH automatic neutralization treatment system from Company A, a major glass manufacturer. H2's pH automatic neutralization treatment system is equipped with our own devices, and the quantitative injection pump is also adopted from our company. ●Accurate injection of small amounts below 10 mL/min. The injection of caustic soda required a small amount of injection below 10 mL/min. Additionally, the operation is batch-type, and due to the infrequent nature of the site, responsiveness and recovery in case of air contamination were concerns. H2's quantitative diaphragm pump optimizes the volume change rate of the pump head and the diaphragm shape, achieving both prevention of air lock and quantitative performance, thus enabling precise injection even under severe conditions.
Sending "the same amount" of liquid 2 is also cleared!
●Making small-scale sewer pipe work easier We received an inquiry from Company T in the Kanto region, stating, "We want to make the pressure delivery of the chemical solution easier for the chemical injection method aimed at stopping water underground." The chemical solution requires mixing equal amounts of water glass and hardener underground, necessitating corrosion resistance, pressure, and metering capabilities. ●Smaller and lighter than before. Easy to handle! Previously, a large electric diaphragm pump (weighing over 100 kg!) was used, which caused significant difficulties even at simple job sites. However, with H2's air diaphragm pump, it weighs 1/5 of the original, is less than half the size, and can perform the same work as the conventional product. Since it is air-driven by a compressor, it has been rated higher in terms of workability and safety compared to conventional products. The previously concerning "metering capability" was also resolved by adjusting the flow rate at the air input to maintain the same "air supply amount." Mixing the two liquids (in equal amounts) was not an issue either. Cleaning the pump after delivery is also easy, and we received positive feedback in all aspects compared to conventional products.
There are many failures of the bonding liquid circulation filtration pump!
●Failure of the bonding liquid circulation filtration pump There are many failures of air diaphragm pumps - (The item marked with a red circle in the photo is the defective product.) We received a consultation from the maintenance department, and it was noted that the existing pumps from a certain manufacturer had frequent failures, leading to consideration of switching to the H2 model ADD type. The liquid used is bonding liquid (manganese phosphate) which is high temperature and contains slurry. The flow involved drawing from the bonding tank, passing through filtration, and circulating it. After thorough inquiries with the users, it was found that the valves and valve seats were experiencing significant wear due to the slurry. Additionally, considering that SUS (stainless steel) materials tend to have a relatively longer lifespan, we proposed and adopted a specially designed SUS valve seat. ●For those troubled by failures of other companies' pumps The deciding factors for adoption were: 1. The initial cost is overwhelmingly low. 2. The manufacturer’s ability to flexibly respond to special specifications. 3. The option to verify the lifespan of the ball material against the SUS valve seat. 4. Good maintenance characteristics. These four points were evaluated, leading to the adoption. At H2, we provide liquid contact parts arranged for the site as described above.
Transporting AdBlue even in explosion-proof areas!
●Transporting AdBlue in Explosive Areas We want to transport AdBlue quickly and reliably. After receiving inquiries from users, we proposed an air diaphragm pump, which was adopted. - We want to transport from a 1000L storage tank (IBC tank) quickly. - We want self-priming capability and to ensure no residual liquid remains. - We want to transport AdBlue gently without stirring the liquid. - We want to use high-pressure air as the power source so it can be used in explosive areas. - We want the installation to the tank to be simple. All of the above requirements were met, and it was adopted. ●For any inquiries regarding AdBlue pumps and equipment, please feel free to consult us. In explosive areas, electric pumps become explosion-proof and expensive. We want to issue receipts as a simple dispenser. Is there a better pump than the handheld type we are currently using? When it comes to transporting AdBlue, if you have specific ideas but no place to consult, please feel free to reach out to H2!
I want to transport it without breaking the ice!
●I want to transport delicate ice without breaking it. We received an inquiry from a device manufacturer in Mie Prefecture asking if it was possible to gently transport fine ice using a DC drive. We proposed using the DC type of H2's electric diaphragm pump and promptly conducted a demonstration. ●The ice remains intact. With the pulsation-free diaphragm pump from major manufacturer T, the ice was damaged, and the cost was also high. Initially, Company N had doubts about using a diaphragm pump, but the results of the demonstration were astonishing. Since Company N's device is designed to produce fine ice, it was absolutely essential that the ice not be damaged during transport. However, with the SS model, we were able to transport the ice without any damage at all. Company N expressed their satisfaction, saying, "Costs have decreased, and we are very pleased with the results."
Lightweight and easy to use! Introducing a case study of a self-priming electric diaphragm pump.
A company specializing in the recovery of LiBr (lithium bromide) used in absorption chillers and heat exchangers in Aichi Prefecture contacted us, stating that they are looking for a pump that can recover lithium bromide solution in a short time. The pump they had been using was an electric double diaphragm pump, which was quite heavy and difficult to handle on-site, so we proposed the "Electric Diaphragm Pump SN Model" and arranged for them to use a demo unit once. They operated the demo unit, including checking the recovery capacity (suction capability) and corrosion resistance (as lithium bromide is a corrosive liquid), and we gathered their feedback. They expressed positive comments such as "It's small, lightweight, and easy to use" and "I was surprised by its power, more than I expected," leading to its adoption on-site.

The material is custom-made with all SUS specifications! The float that floats in the bond tank is also all SUS.
We received an inquiry from a major surface treatment factory asking if it is possible to recover and separate the oil and sludge floating in high-temperature bonding liquid. They mentioned that there is a simple device already in place, but they are dissatisfied with the recovery efficiency, so they are considering an upgrade. To enable recovery and separation in high-temperature bonding liquid, we decided to custom-manufacture our ADB model in all stainless steel (SUS) specifications. The float to be placed in the bonding tank is also made entirely of stainless steel. We selected the ADD model air diaphragm pump in stainless steel specifications. [Case Study] ■ Delivery: Major surface treatment factory ■ Application: Separation and recovery of floating oil in bonding liquid ■ Model: ADB-15-SS (SUS specification) *For more details, please refer to the PDF document or feel free to contact us.
It is possible to transport high-viscosity slurry liquids! Here are examples of air diaphragm pump deliveries.
A major paint manufacturer consulted us about wanting to transfer high-viscosity liquid from a stirring tank. Based on the conditions of "high-viscosity paint with a viscosity of about 10,000 CP," "a horizontal draw of 3 meters from the tank is required," and "transfer to the production machine after self-priming," we proposed the ADD type air diaphragm pump. After delivery to the user, we received a call saying it "doesn't suck." Upon discussing the situation, we found that the conditions for the liquid, air supply, and installation were all fine, and we were puzzled as to why it wasn't working. However, from the installation photos provided by the customer, it became clear that the suction inlet diameter was restricted. The pump diameter is 15A, but it was narrowed down to 9A. When we requested the use of a hose with an inner diameter of φ15, it began to self-prime without any issues, and we received words of gratitude.

Introducing a case study of delivering urea water in large volumes over a distance of 30 meters using an air diaphragm pump!
We received an inquiry from a major chemical plant regarding the desire to transfer urea water from the ground to a ship at a port where the ship docks. The specifications requested were: "transfer rate of 200L/min," "self-priming and resistant to dry running," "lifting height of 30m," and "to be portable, with the compressor mounted on a cart." In response, we delivered the air diaphragm pump "ADD-40-PP." Since long-distance transfer via hose was anticipated, we also included a pulsation dampener in the unit. We selected a compressor tailored to the customer's specifications and delivered it as a complete unit. [Case Study] ■ Delivery: A certain chemical plant ■ Application: Transfer of urea water from the port to the ship ■ Model: ADD-40-PP (Air Diaphragm Pump) + Compressor Unit *For more details, please refer to the PDF document or feel free to contact us.

The gear pump is breaking down immediately, and it's a problem. It can handle high temperature, slurry, and high viscosity at a low cost!
We received a consultation from Company J, a major steel manufacturer, stating that "the gear pump breaks down immediately, 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 gets mixed in, leading us to conclude that the slurry was causing the gear pump to fail. Therefore, we proposed the "Air Diaphragm Pump ADD type," and after they used a demo unit, it was adopted. 【Features of our diaphragm pump】 ■ Self-priming ■ Capable of pressure delivery ■ Can transfer slurry and viscous liquids ■ Suitable for high-temperature fluids *For more details, please refer to the PDF materials or feel free to contact us.
We transported custard cream using our pump.
As the quality and variety of convenience store bread continue to increase year by year, production factories are required to ensure accurate and efficient operations while also considering the "ease of work" for their employees. Due to the challenges of efficient production and reducing work load, we received inquiries from major convenience store bread factories, and they adopted A2's pump for the process of transferring custard. Since custard cream is transferred at low temperatures and is almost solid, we selected the sanitary air diaphragm pump "SB series" as the transfer pump. Although the initial self-priming took a bit of time, it generally demonstrated satisfactory transfer capacity for the customer, and its lightweight and compact design were well received, with easy disassembly and cleaning being highly praised. In this document, we visited the factory where our pump was actually adopted and inquired about the challenges and background of the request. For more details, please download the document and check it. [Overview] ■ Delivery: Major convenience store bread manufacturing factory in Saitama Prefecture ■ Application: Transfer of custard cream (with control) ■ Model: Sanitary diaphragm pump SB type
I want to transfer custard cream! Using a non-contact sensor, ON-OFF based on liquid level.
We received a request from a major convenience store bread manufacturing factory stating, "We would like to transport custard cream." Initially, we proposed only a pump, but the order expanded to include liquid level control, as the system would stop when the hopper at the destination reached full liquid level. Since the custard cream is nearly solid due to low-temperature transport, we selected the sanitary air diaphragm pump SB series for the transport pump. Non-contact sensors were used for liquid level control, monitoring and controlling the custard cream's liquid level from two points. The lightweight and compact design was well-received, and it was praised for being easy to disassemble and clean. Additionally, we were delighted to hear that the fact that "even though we are a pump manufacturer, we can handle everything" was a decisive factor for choosing H2. We would be grateful if customers considering stringent fluid transport could contact us.

The viscosity of intermediate raw materials for cosmetics is 300 cp! We propose the SB series of sanitary diaphragm pumps.
We received a request from a cosmetics manufacturing factory in the northern Kanto region, stating, "We would like to transport intermediate raw materials for cosmetics." They mentioned that as long as the transportation could be done roughly, it would be fine, so we proposed the SB series of sanitary diaphragm pumps. The viscosity of the intermediate raw materials for cosmetics was said to be 300 cp, but there were no issues with the transportation. Although this unit is treated as a backup, they appreciated its lightweight design and high cost performance. We have demo units of the SB series sanitary diaphragm pumps available, so customers who would like to "try it out" are welcome to contact us. 【Case Details】 ■ Delivery: Cosmetics factory in northern Kanto ■ Application: Transportation of intermediate raw materials for cosmetics ■ Model: Sanitary diaphragm pump SB-30 *For more details, please download the PDF or feel free to contact us.
