Technical Handbook: Basic Knowledge of Pumps - Effects of Viscosity

Technical Handbook: Basic Knowledge of Pumps - Effects of Viscosity

Topics related to viscosity that you can't ask about now!

This document introduces the effects of viscosity. In the world, there are various liquids ranging from low viscosity to high viscosity. What does the difference in viscosity affect? The answer is piping resistance. Piping resistance refers to the pressure in that line. [Effects of Viscosity] ■ If we compare it to humans ■ In the case of pumps ■ Cavitation and countermeasures *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Solving Wear from High-Concentration Slurry and Improving Coating Precision

[Case Study] Solving Wear from High-Concentration Slurry and Improving Coating Precision

To solve the challenge of needing to send liquid at a constant flow rate to achieve a uniform coating surface! Here is a case study from an electronic components manufacturer.

The electronic components manufacturer was using a gear-type pump to supply a slurry-like high-viscosity liquid (3000 mPa·s) to the coating machine. However, there were issues such as "the slurry particles getting clogged in the pump, causing it to stop" and "severe wear of the pump, leading to a decrease in flow rate in a short time." For solutions to these issues and requests, please download and view the PDF materials. 【Customer's Issues and Requests】 ■ Slurry particles sometimes clogged the pump, causing it to stop. ■ The pump experienced severe wear, resulting in a decrease in flow rate in a short time. *For more details, please refer to the PDF materials or feel free to contact us.

Gear Pump "OH(B)-jG Type / OH(B)-JjG Type"

Gear Pump "OH(B)-jG Type / OH(B)-JjG Type"

Equipped with a jacket that can be heated or cooled with water!

The "OH(B)-jG type and OH(B)-JjG type" are gear pumps based on the OH-G type gear pump, equipped with jackets that allow for heating or water cooling on the outer circumference of the stuffing box, making them suitable for transporting high-temperature liquids. To prevent the alteration of the liquid at the gland section and to cool the bearings, water cooling is used; conversely, heating is employed to prevent the liquid from sticking at the gland. The OH-jG type and OH-JjG type feature casings with jackets to transport high-melting-point liquids in a dissolved state, and they are also equipped with jackets on the outer circumference of the stuffing box. 【Features】 ■ Optimal for transporting high-temperature liquids ■ Equipped with jackets for heating and cooling ■ Capable of transporting high-melting-point liquids in a dissolved state *For more details, please refer to the catalog or feel free to contact us.
