CAUTION! Risk of injury and damage to property!
Non-approved fluids can damage the pump and also cause injury.
Comply strictly with the relevant safety data sheets and manufacturer's data!
2)
•
Observe the specifications of the manufacturer regarding the mixing ratios.
2)
•
Additives are to be mixed to the fluid on the pressure side of the pump, even if this
is contrary to the recommendations of the additive manufacturer!
CAUTION! Risk of property damage!
When changing, refilling or replenishing the fluid with additives, there is a risk of mate-
rial damage caused by enrichment of chemical substances. The pump is to be flushed
separately for a sufficient amount of time to ensure the old fluid has been completely
removed from the interior of the pump.
For alternating pressure flushing, the pump must be detached. Chemical flushing is not
suitable for the pump; in this case, the pump must be removed from the system for the
duration of cleaning.

6 Description and function
6.1
Description of the pump
The pump consists of a hydraulic system, a glandless pump motor with a permanent mag-
net rotor, and an electronic control module with an integrated frequency converter. The
control module contains a red operating knob (Fig. 1, item 4) that can be used to set the
pump's differential pressure to an adjustable value between 1 and 5 m. The pump housing
is clad with an insulating shell for thermal insulation.
