Description
DMX 321-6 B-PP/T/T-X-E1U3U3XEMAG | The pump of the DMX series is a versatile positive displacement diaphragm dosing pump. The diaphragm is coupled mechanically 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: 10. The liquid end is composed of: Dosing head
PTFE coated diaphragm
Single ball valvesOther features: Robust industrial pump with aluminium enclosure
Easy to install and operate design
Long life PTFE coated diaphragm
Optimum capacity and stroke frequency graduation
Dosing flow variation < ±1. 5%, linearity
±4%Applies only to pumps with: ATEX certification The dosing pump DMX 226 is certified according to the ATEX guideline RL 94/9/EC for non-electrical operating supplies. The motor versions EEx e and EEx d defined by Grundfos/Alldos are certified by the manufacturers according to ATEX guidelines for electrical operating supplies. The motor type plate is labelled according to ATEX. Electronics features: Applies only to pumps with control variant: AR Etron Profi microprocessor electronics, direct attached to motor: Stroke frequency adjustable from 1 stroke/min to maximum stroke frequency
Pulse control with multiplier and divisor
Analog signal control 0/4-20 mA
Level control with input for two level signals.
Pulse, analog and remote on/off input
Analog output
Alarm relay outputStroke output
Input for dosing controller and diaphragm monitoring sensor Applies only to pumps with control variant: AT0Automatic adjustment of stroke length via direct drive control or mA-input signal
Block-proof synchronous motor with feedback potentiometer
Two limit switches
