Hydro (hydraulic type)

✔ High pressure, high precision motor driven hydraulic diaphragm type metering pump
✔ Discharge reproduction accuracy ± 1% with stroke adjustment range of 20 to 100%
✔ Diaphragm damage detection sensor installed as standard


Supports discharge pressure up to 10.0MPa with hydraulic diaphragm

In addition to the normal single head type, we have a lineup of double head (boxer) types equipped with two heads.
Furthermore, it is also possible to connect multiple pumps with one motor and operate them at the same time.
In addition, the pump is equipped with a pressure rise avoidance [internal relief] function _and a diaphragm damage detector as standard equipment, which is characterized by high safety.


● Boiler chemical injection (separate cans, additives, etc.)
● Quantitative injection of reaction solutions, catalysts, etc. into chemical processes


Model specifications

Hydro / 2: Maximum discharge amount 3.0 to 68.0 L / h Maximum discharge pressure 2.5 to 10.0 MPa (maximum 2.5 MPa for PVDF head)
Hydro / 3: Maximum discharge amount 10.0 to 170.0 L / h Maximum discharge pressure 2.5 to 10.0 MPa (Maximum 2.5 MPa for PVDF head)

● Supports single head and double head. Double head is a boxer type that alternately inhales / discharges
● The stroke length of each head can be set independently and the flow rate can be adjusted individually.

Wetting part

● Injection accuracy: Stroke length range 20-100% Reproducibility ± 1% (under the operating conditions specified by the manufacturer)
● There are three types of wetted parts (heads): PVDF type, SUS316Ti type, and Hastelloy C type.
● Diaphragm damage detector standard equipment 3-layer diaphragm
