Trochoidal type internal gear pump

Trochoidal type internal gear pump

It is the optimal pump for lubrication, hydraulic, high-pressure coolant, and combustion use.

The internal gear pump is a pump that operates using an internal gear mechanism, where the external gear and internal gear mesh together and rotate while tracing a trochoidal curve. As a result, it experiences minimal wear, is compact, and can discharge large volumes with low noise. ★Features * The simple structure makes disassembly and maintenance of parts easy. * The rotor set experiences minimal wear and has a long lifespan. * Compared to other gear pumps, it produces less noise. * Due to mass production, it is inexpensive and has consistent quality. * There is minimal pulsation in the oil flow. * It has a wide range of operating speeds (500 to 4000 rpm). * There is a wide variety of types according to flow rate stages.

Trochoidal type internal gear pump for chemical raw materials

Trochoidal type internal gear pump for chemical raw materials

For the transport of anaerobic liquids! Ideal for transporting liquids that must not come into contact with air, such as polyurethane raw materials!

The internal gear pump is a pump that operates on the principle of an internal gear mechanism, where an external gear and an internal gear mesh together and rotate while tracing a trochoidal curve. This pump, specialized for chemical raw materials, uses two seals made of special PTFE (Teflon) and fills the space between the seals with solvents or plasticizers. It can safely isolate the external air, preventing the curing of isocyanates due to contact with the outside air. It is ideal for the transfer of urethane raw materials (isocyanates, polyols). 【Features】 ● For the transport of anaerobic liquids 　→ By using special PTFE (Teflon) seals and sealing the liquid between the seals, it prevents contact between the liquid and external air. It is optimal for transporting liquids like isocyanates, which are strictly prohibited from contact with air. ● For use at high temperatures 　→ This model can withstand temperatures up to 120°C. If you require higher temperatures, please consult us. ◎ Download the catalog 　→ You can view the specifications of all 11 models. Additionally, we also offer internal gear pumps for fuel oil. You can find more details by downloading the same catalog.

Internal gear pump *All motors comply with IE3 regulations!

Internal gear pump *All motors comply with IE3 regulations!

New development! An internal gear pump that is a must-see for those looking to reduce the introduction cost of the IE3 motor (750W)!

In Japan, from April, IE3 high-efficiency regulations have been introduced for motors over 750W, and our company's motors for internal gear pumps are fully compliant with IE3. Additionally, for customers who desire a 750W motor but want to keep the introduction costs for IE3 motors low, we have newly developed a 700W motor that offers performance comparable to 750W. We encourage you to consider this option. 【Features】 ■ Low wear ■ Compact and capable of high capacity with low noise ■ Maximum discharge pressure: 4.0MPa ■ Maximum discharge flow rate supports up to 659.7L/min *For more details, please download the catalog or contact us directly.

Trochoidal type internal gear pump (for fuel oil, for chemical raw materials)

Trochoidal type internal gear pump (for fuel oil, for chemical raw materials)

This pump uses multiple special seals and is capable of effectively transferring waste oil, isocyanates, polyols, and more!

An internal gear pump is a pump that operates using an internal gear mechanism, where an external gear and an internal gear mesh together and rotate while tracing a trochoidal curve. The products for transferring fuel oil use three special PTFE (Teflon®) seals and isolate the bearings from the oil. As a result, wear on the bearings is minimized, allowing for a long lifespan even during the discharge of waste oil. Additionally, the products for transferring chemical raw materials use two special PTFE (Teflon®) seals and fill the space between the seals with solvents or plasticizers, which completely blocks outside air and prevents the hardening caused by the contact of isocyanates with outside air.

Trochoidal type internal gear pump for fuel oil

Trochoidal type internal gear pump for fuel oil

For extending the lifespan of bearings! It's okay even with waste oil spraying or slurry-mixed coolant.

The internal gear pump is a pump that operates with an outer gear and an inner gear meshing together, rotating along a trochoidal curve. This pump, specialized for fuel oil, uses three special PTFE (Teflon) seals to isolate the bearings from the oil. This reduces bearing wear and allows for a long lifespan even when discharging waste oil. 【Features】 ● Prolonged bearing lifespan 　→ By using special PTFE (Teflon) seals, the bearings are isolated from the liquid. This minimizes uneven wear on the bearings, allowing for a long lifespan even in coolant stations where slurry from waste oil spraying is mixed in. ● Suitable for high-temperature use 　→ This model can withstand temperatures up to 150°C. If you require higher temperatures, please contact us. ◎ Download the catalog 　→ You can view the specifications of all 11 models. Additionally, we also offer internal gear pumps for chemical raw materials. You can find more details by downloading the same catalog.
