DN Series
Diaphragm Dosing Pumps Without Spring
Features & Cautions
- Without spring to help suction process, the technique which is crank rod mechanism is adopted to this product.
- The suction and discharge process are very accurate more than the previous model due to crank rod mechanism.
- The crank rod mechanism guarantee the lager capacity and the higher pressure.
- Simple, Economic Vertical type Metering pump by reasonable design.
- Extremely good life by long operation
- The range of effective adjustment stroke : 20%~100%
- The temperature of pumping liquid : 0~100℃
- The viscosity of pumping liquid is Below 1000cp
- Simple, Economic Vertical type Metering pump by rationalistic design.
- Extremely good life by long operation.
- The range of effective adjustment stroke : 15~100%
- The temperatures of pumping liquid : 0~50℃ (Material : PVC), 0~80℃ (Material : SUS)
- Above specifications are that should be changeable due to improvement etc without any notice.
