Water pump DMH HYDRAULIC PISTON

cast iron

DMH hydraulically actuated piston diaphragm dosing pumps from 0.15 l/h up to 2 x 1500 l/h, with a pressure range from 200 to 4 bar General The Grundfos DMH range is a series of extremely strong, robust pumps for applications requiring a reliable dosing and high-pressure capability, such as process engineering. The DMH 28x has been especially designed for high-pressure applications from 50 up to 200 bar. The range is highly versatile: it covers a wide flow range and offers a variety of dosing head sizes, materials and accessories. Customers worldwide have enjoyed years of trouble-free operation from their DMH pumps. Accurate dosing - all the time DMH pumps have a very high dosing accuracy and allow an exact reproducibility. For DMH25x, the dosing flow fluctuation is <± 1.5 % within the 10-100 % control range, and the linearity deviation is ± 2 % of the full-scale value. For DMH28x, the dosing flow fluctuation is <± 1.0 % within the 10-100 % control range, and the linearity deviation is ± 1 % of the full-scale value. Smooth and low-pulsation dosing The DMH range combines sophisticated drive technolo­gy and gear kinematics to ensure smooth and low-pulsation dosing without pressure peaks. This means less stress to all system components, such as tubes and valves, and leads to longer service intervals for the entire system. Motors to match application needs For applications with specific motor requirements, the versatile DMH range offers high-quality motors for 50 Hz, 60 Hz, 100 Hz (with Variable Frequency Drive VFD), as well as EX classified or ATEX-certified motors, if required.
