TZKa, TZHa
Checking flow of hydraulic oil TZHa only: after the pump has been running for a short while, check that hydraulic oil is flowing
Checking leakage TZKa only: check that the leakage of the feed chemical is between 10 to 120 drops/min.
Checking oil level Check whether the oil level in the pump is visible in the oil inspection glass.

6 mm = 100 % stroke length
(10 revolutions)
Stroke adjustment wheel: note the following:
1 revolution = 10 %
1 long increment = 1 %
1 short increment = 0.5 %
20 mm stroke length = 100 %
(10 revolutions)
Stroke adjustment wheel: note the following:
1 revolution = 10 %
1 long increment = 1 %
1 short increment = 0.5 %
NOTE
• For viscous media, select a stroke length as long as possible!
• For effervescent media, select a stroke length as long as possible!
• For good intermixing, select a stroke frequency as high as possible!
• For precise dosing with volume-proportional dosing, do not set the stroke length
below 30 % (TZKa: 10 %)!
through the hose to the bleed valve.
You should carry out this check to ensure that the pump has not lost oil due to unprofessional
transportation. It may have suffered damage as a consequence.
3.78 mm = 63 % stroke length
(6 revolutions and 3 long increments)
12.6 mm = 63 % stroke length
(6 revolutions and 3 long increments)
