4000H Series Constant Temperature Liquid Delivery Pump System

This is a constant temperature liquid delivery pump suitable for solvents that facilitate smooth liquid delivery by raising the temperature of viscous and viscous liquids to above 100°C.

Fluids such as oils and paints have high viscosity at room temperature, resulting in significant delivery errors and, moreover, making delivery impossible. Therefore, this is a constant temperature delivery pump designed to accommodate special analysis and measurement equipment that enables fluid delivery by heating the pump head to a high temperature. However, it cannot heat the fluid itself, so please heat the solvent to above the specified temperature. The basic mechanical component is a 4000 series general-purpose high-pressure delivery pump. To enhance operability and heat retention, a larger heat jacket has been added by mounting it on the side head of the 4000 series main unit, allowing for heating of the piping to prevent solidification within the pipes. The digital pressure gauge (photo: on top of the delivery pump) is separated from the 6120 series into five models with the required rated pressure for easier maintenance, and the delivery pump can also be selected from seven models with a maximum flow rate of 3.0 to 50 ml/min. Additionally, through innovations such as heat sinks from the heat block to the pump drive unit, the thermal conductivity has been improved by about 10% compared to the previous model, with a design focus on preventing grease from dripping in the drive unit. Heaters are set vertically within the heat block, and their capacity has been increased to ensure thermal stability.
