MECHANICAL DMH
Hydraulic Piston diaphragm pump
DMH range of metering diaphragm pumps piston hydraulically operated for flow rates of 0.15 l/h to 2 x 1500 l/h and pressures between 200 and 4 bar.
Grundfos DMH range consists of extremely resistant and robust, pumps designed for applications that require reliable dosage features and capacity to develop high pressures, such as those related to process engineering. The model 28 DMH 28x has been designed for applications where it is necessary to have high pressures (between 50 and 200 bar). It is a highly versatile range: covers a wide range of flow rates, offers dosing heads of different sizes, is available in different materials and incorporates a wide range of accessories. Customers all over the world have enjoyed years of their bombs DMH seamlessly.
The DMH pumps have features of high precision dosage and facilitate the reproduction of operations with great accuracy. Pumps DMH 25 x, the fluctuation of the dosing flow is less than ± 1.5% within the control range (10-100%), while the linearity deviation is ± 2% of the maximum value of the scale. DMH pumps 28 x, the fluctuation of the dosing flow is less than ± 1.0% within the control range (10-100%), while the linearity deviation is ± 1% of the maximum value of the scale.
The models available are:
- DMH 50 litres – 200 bar
- DMH 105 litres – 100 bar
- DMH 222 litres – 50 bar
