Description

DMH 12-16 B-PVC/E/C-X-E1U2U2XE0AG | The pump of the DMH series is a versatile positive displacement diaphragm dosing pump. The diaphragm is coupled hydraulically via a precise gear-eccenter-tapet-system to a high efficiency AC motor. The dosing capacity is adjusted by varying the stroke length at the stroke adjustment knob in the ratio 1 to 10. 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. The Grundfos DMH range is a series of extremely strong, robust pumps for applications requiring reliable dosing capability, such as process engineering. The liquid end is composed of: Dosing head
PTFE diaphragm
Ball valvesOther features: Robust industrial pump with aluminium or cast iron enclosure
Easy to install and operate design
Long life PTFE diaphragm
