Non-contact low-share pump tank mixer PTM-1/3/4

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.

[Case Study] High-Temperature Slurry Mixed Viscosity Liquid (Oil)

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.

【Case Study】Micro Injection of Neutralizing Agent

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.

[Delivery Example] Pumping with Liquid Injection Method

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.

[Case Study] Circulation Filtration of Bond Liquid (Manganese Phosphate)

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.

[Delivery Example] Transfer of Ad Blue in a Hazardous Area

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!

[Delivery Case] Transport of Fine Ice

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."

[Delivery Example] Recovery (Extraction) of Lithium Bromide Solution

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. [Case Study] ■ Delivery: A certain company in Aichi Prefecture ■ Application: Extraction of lithium bromide solution from an absorption chiller ■ Model: Electric Diaphragm Pump SN Model *For more details, please refer to the PDF document or feel free to contact us.
