Takasago's quantitative dispensing pump: discharge volume adjustment method and recommended installation direction.

Introducing the method for adjusting the discharge volume of a quantitative dispensing pump and the recommended installation direction!

The quantitative dispensing pump allows you to change the discharge amount per cycle by rotating the discharge amount adjustment screw. Rotating the adjustment screw to the right (in the direction of pushing the product in) decreases the discharge amount, while rotating it to the left (in the direction of pulling the product out) increases the discharge amount. After adjusting the discharge amount, please secure it with the screw lock nut. The range of adjustment for the discharge amount is from the maximum point when fully pushed in with a right rotation (discharge amount 0 mm³) to several rotations with a left rotation. Additionally, please refer to the image for the recommended installation direction. 【Discharge Amount Adjustment Range】 ■ Model: MCP-50 ・ Number of rotations: 2 ■ Model: MLP-200P ・ Number of rotations: 3 ■ Model: PKP-500P ・ Number of rotations: 4 *For more details, please refer to the PDF document or feel free to contact us.

Takasago's quantitative dosing pump - Other items that may affect the discharge amount.

Takasago's quantitative dosing pump - Other items that may affect the discharge amount.

Items that affect discharge volume, such as the occurrence of bubbles and operation after prolonged standing, and their countermeasures.

We introduce the causes and countermeasures regarding the factors that affect the discharge volume of the "Takasago quantitative dispensing pump." In the case of bubble formation, gas dissolved in the fluid may change into bubbles, leading to the occurrence of bubbles within the product and the piping, or leaks from fittings and other piping components. This can result in a decrease in discharge volume and poor reproducibility, so it is recommended to degas the fluid used. If the product is left unused for an extended period, the set discharge volume may change, and reproducibility may worsen. It is advisable to drain the fluid from the product for storage when not in operation for a long time. When using soft tubes such as silicone tubes in the piping, the suction and discharge pressure generated by the product may be absorbed by the elasticity of the soft tube. This can negatively impact the discharge volume and reproducibility, so it is recommended to use hard tubes such as fluoropolymer tubes in the piping. Additionally, there are other factors that can affect discharge volume and reproducibility beyond the items mentioned above. Please feel free to contact us if you have any questions. *For information on quantitative dispensing pumps, please refer to the PDF materials or feel free to contact us.*

Precautions for Using the Takasago Quantitative Discharge Pump

Precautions for Using the Takasago Quantitative Discharge Pump

Introducing the precautions for using Takasago's quantitative dispensing pumps!

This is a notice regarding the usage precautions for the "Takasago Quantitative Discharge Pump." ■ If the initial set discharge amount is low, it may take a long time to completely replace the gas inside this product and the piping with liquid. Setting the discharge amount close to the maximum value during initial discharge will speed up the replacement. ■ The efficiency of gas discharge varies depending on the installation direction of this product. It also affects the discharge of bubbles generated in the fluid, so it is recommended to install it in the specified direction. ■ The set value may change due to loosening of the discharge amount adjustment screw. Please tighten the lock nut securely. ■ When reducing the discharge amount by turning the discharge amount adjustment screw to the right, do not turn the screw with excessive torque beyond the adjustment range. This may cause a malfunction. ■ When increasing the discharge amount by turning the discharge amount adjustment screw to the left, do not over-rotate the screw. If the screw is turned beyond the maximum discharge amount, there is a risk that the discharge amount adjustment screw may come off the product and internal components may fall out. * For information about the quantitative discharge pump, please refer to the PDF document or feel free to contact us.
