Grundfos DMX 75-4 B-PVC/E/SS-X-G1U3U3FEMNG (99772135)

The 221 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
  • Double ball valves up to 50 l/h and single ball valves from 60 l/h

Other features:

  • Robust industrial pump with chemical resistance plastic enclosure
  • Easy to install and operate design
  • Long life PTFE coated diaphragm
  • Optimum capacity and stroke frequency graduation
  • Dosing flow variation ±1.5% (FS), linearity ±4% (FS)

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
  • Analogue signal control 0/4-20 mA
  • Level control with input for two level signals.
  • Pulse, analogue and remote on/off input
  • Analogue output
  • Alarm relay output
  • Stroke output
  • Input for dosing controller and diaphragm monitoring sensor

Applies only to pumps with control variant: D3

  • Automatic adjustment of stroke length via direct drive control or mA-input signal
