【Delivery Case】Transport of Ceramic Slurry

Self-priming and pumping of high-viscosity slurry!

● Self-priming and pumping of high-viscosity slurry We received an inquiry from a major chemical company, Company S, regarding the transfer of ceramic slurry. Ceramic slurry is a high-viscosity liquid with particle inclusion, and this time, self-priming capability and pumping capability were also part of the evaluation. We proposed the ADD model air diaphragm pump, which was used on-site. The evaluation was very positive, and the on-site personnel were convinced, leading to its adoption. ● Key factors for adoption by a major chemical company The key factors for adoption were: 1. Initial costs are lower compared to other companies. 2. Flexible response as a manufacturer to special specifications. 3. Consumables (such as diaphragms) are also cheaper compared to other companies. 4. High evaluation of transfer and pumping capabilities with the demo unit. Based on the above four points, it was adopted. The features of the diaphragm pump are "self-priming," "pumping capability," and "ability to transfer slurry and viscous liquids." We also have demo units available, so please feel free to contact us.

Delivery Case: Transfer of Adhesive (High Viscosity Liquid)

I want to transfer the adhesive from the one-gallon can so that women can work too!

●Improvement for Women to Work We received a consultation from Company B, a major manufacturer in Aichi Prefecture, stating, "We have been lifting adhesive (in a 20-liter can) to refill it at the top of the tank, but is there a way to transfer it using a pump?" The adhesive is a high-viscosity liquid containing ethyl acetate and toluene, and since it was in an explosion-proof designated area, we proposed an air diaphragm pump of the ADD type in stainless steel (SUS) specification. Given that the viscosity of the adhesive was 12,000 CP, we selected a 25A diameter to ensure a comfortable margin. The transfer was completed without any issues. Subsequently, to reduce operational noise, we added a higher-grade silencer, and we also custom-built a mounting frame (SUS) for the pump. ●Meeting User Needs We received positive feedback from the user, stating, "It was very helpful due to the company's policy of enabling women to work." Additionally, we proposed and adopted a dedicated hose fixing device because it was dangerous for the hose to come off when inserting it into the 20-liter can. Once the adhesive transfer is completed, the next step is to transfer the next 20-liter can, so we made it possible to change the hose with minimal contact with the chemicals.

[Case Study] Oil Separation from Coolant Tank

Introducing a case study of coolant tank floating oil recovery for FANUC's RoboDrill.

We received an inquiry from a metal processing product manufacturing company regarding the recovery of floating oil from their coolant tank. The ADB-15-PP was selected as suitable, and after testing it with a demo unit, they decided to implement it. Floating oil in water-soluble coolant tanks can lead to processing defects in the manufactured products and unpleasant odors. With the ADB model, recovery using an air diaphragm pump results in fewer troubles and is easy to operate. We recommend trying it out with a demo unit first to see the effectiveness for yourself. [Case Study] - Delivery: Metal processing product manufacturing company - Application: Recovery of floating oil from the coolant tank of a Fanuc RoboDrill - Model: ADB-15-PP *For more details, please refer to the PDF materials or feel free to contact us.

[Delivery Example] Transport of Viscous Slurry (Water and Oil-Free Explosion-Proof Specification)

I want to transport a viscous slurry in a harsh environment! Since exposing the resin is not allowed, we custom-made a cover.

We received a request from a major chemical company stating, "We would like to send a fluid mixture of solid matter at around 2000 cp (30% wt)." Upon further inquiry, they specified that the equipment must be explosion-proof, treated to prevent water and oil contamination, and require contamination-free conditions for product use. Additionally, they requested that the wetted parts be made of SUS or only PTFE if using resin, which was quite stringent. In response to these requirements, we selected the "SB-75" sanitary air diaphragm pump, and for the high-viscosity slurry, we proposed using SUS316 for the ball. While we selected PTFE for the pump body material, it was specified that exposed parts were not acceptable, so we custom-made a cover to encase everything in SUS. Since the piping connection was to be a 40 AJIS flange, we also manufactured an adapter to convert from a helix to a JIS flange. If you are having trouble with the transfer of high-viscosity slurry liquids, please feel free to contact us. [Case Details] ■ Delivery: Major chemical company ■ Application: Transfer of a mixture of hazardous fluids and solids ■ Model: SB-75 (with cover specification) *For more details, please refer to the PDF document or feel free to contact us.

[Delivery Example] Transferring 3000cp viscosity liquid from a drum.

Capable of handling high viscosity and high temperatures! Introducing case studies of air diaphragm pump deliveries.

A steel company in Hokkaido contacted us, stating, "We purchased an air diaphragm pump from Company Y, but it stopped immediately, and we are in trouble." We responded to their inquiry. Upon further hearing their details, they wanted to transfer a liquid with a viscosity of about 3000 cp at a rate of approximately 25 L/min from a drum. The discharge was to be horizontal for 2 meters and vertical upward for about 1 meter (with a resin filter in between), while the suction side was horizontal for 1 meter. Given these conditions, our air diaphragm pump had sufficient track record, so we lent them a demo unit, which performed well, leading to an order. As a result, they later placed an additional order for two more of the same pumps, making it a highly satisfactory case. [Case Details] ■ Delivery: Steel Company ■ Application: Transfer of high-viscosity paint from a drum ■ Model: ADD-25-AL (Air Diaphragm Pump) *For more details, please refer to the PDF document or feel free to contact us.

[Pump Delivery Case] Transferring 3000 cp Viscosity Liquid from a Drum

Solving the problem of 'immediate shutdown with products from other companies'! Capable of handling high viscosity and high temperatures.

We received a contact from a steel company in Hokkaido stating, "We purchased an air diaphragm pump from Company Y, but it stopped immediately, and we are in trouble." Here is a case we handled. They wanted to transfer a liquid with a viscosity of about 3000 cp at a rate of approximately 25 L/min. The discharge was horizontal for about 2 meters and vertical upwards for about 1 meter (with a resin filter in between), while the suction side was horizontal for 1 meter. There are two major differences between our ADD and other companies' products, both of which are key points for transferring high-viscosity liquids. In this case, they later ordered two additional pumps of the same model as a repeat order, resulting in a highly satisfactory outcome. [Features of our ADD] - The diaphragm uses two pieces on one side (four in total), making it strong against negative pressure and positive force. - There is a wide selection of ball materials for discharge and suction, and the sealing capability due to the valve seat is high. *For more details, please refer to the PDF document or feel free to contact us.

[Delivery Case] Transfer of Custard Cream

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. [Case Details] ■ Delivery: Major convenience store bread manufacturing factory in Saitama Prefecture ■ Application: Transport of custard cream (with control) ■ Model: Sanitary diaphragm pump SB type *For more details, please refer to the PDF document or feel free to contact us.
