Gear pump: Increases operating efficiency with a quick exchange pump!

Gear pump: Increases operating efficiency with a quick exchange pump!

Attention those struggling with gear pump failures or poor operating efficiency! You can improve your operating efficiency with an immediate replacement pump!

From laboratory level to mass production level, gear pumps are used for applications such as the transfer of high-viscosity fluids like molten resins, elastomers, adhesives, and hot melts. If you are struggling with gear pump failures or poor operating efficiency, this is a must-see! You can improve operating efficiency with an immediate replacement pump! When trying to replace a malfunctioning gear pump that is currently in operation, many people express concerns about the rising replacement costs due to the successor model having changed to a next-generation type. Currently, we are offering materials summarizing the effects of replacement and points to check for the timing of gear pump replacement! [Effects of Replacement (Excerpt)] ■ Full Replacement: Same Size Replacement (M Company’s First Generation Pump) - Simply replacing the pump allows for an upgrade to a new pump. - Minimal work is required as no adjustments are needed, and the motor, reducer, and universal shaft can be reused as is. - Replacement significantly improves volumetric efficiency and wear resistance. *For more details, please refer to the external link or PDF materials, or feel free to contact us.

[New Theory] Gear Pump Utilizing the Characteristics of High Viscosity Resin

[New Theory] Gear Pump Utilizing the Characteristics of High Viscosity Resin

The new theory "Watanabe Theory" achieves high effectiveness by being applied to the extrusion molding of high-viscosity resins! A gear pump has achieved a volume efficiency of over 95%.

The "Watanabe Theory" refers to the concept of estimating resin viscosity using shear rates that take into account the reverse flow velocity during reverse flow calculations within a gear pump. The application of this theory to the shape of the gear pump has resulted in our company's design of the "DEX Gear Pump." As a result, we have achieved a volumetric efficiency of over 95% for PS-based resins at a pressure boost of 150 to 180 Bar. [Features (DEX Gear Pump)] ■ Application of the "Watanabe Theory" to the shape of the gear pump ■ Achieved volumetric efficiency of over 95% *For more details, please refer to the external link or PDF materials, or feel free to contact us.

For the spinning industry: Stabilization of discharge volume 【【Gear Pump Unit】】

For the spinning industry: Stabilization of discharge volume 【【Gear Pump Unit】】

To a more accurate discharge volume delivery.

A gear pump is a pump that has a gear structure and is widely used in industry. It is used in equipment with hydraulic systems, such as hydraulic excavators and forklifts. There are few contact points other than the gears and casing, making disassembly relatively easy, and it is used in a wide range of industries. Our company is capable of designing and manufacturing units that use gear pumps. *Please note that we will use purchased gear pumps.

Issues with involute gear pumps

Issues with involute gear pumps

During expansion, a vacuum is created, causing the air in the liquid to separate and bubbles to form! I will explain the issues.

The involute gear pump has a variable trapped volume at the meshing part as the gears rotate. During contraction (Figure A), it generates abnormally high pressure, which puts stress on the bearings and causes vibration and noise. Additionally, during expansion (Figure C), a vacuum is created, leading to the separation of air in the pumped liquid and the formation of bubbles. As clearly shown in the figures, the inter-tooth volume at the meshing part has a narrow inlet, which causes cavitation during the inflow of the pumped liquid, resulting in vibration, noise, pitting, and reduced efficiency. 【Issues (Partial)】 ■ The inter-tooth volume at the meshing part has a narrow inlet, causing cavitation during the inflow of the pumped liquid. ■ Causes vibration, noise, pitting, and reduces efficiency. ■ The slip rate of the gears is large, and there are significant fluctuations at the meshing point. ■ Promotes wear of the gears, leading to decreased capacity and power loss. *For more details, please refer to the PDF document or feel free to contact us.
