* Observe the maximum permissible temperatures and that the friction loss increases with the viscosity of the dosing medium.
** The maximum dosing flow of HV-variant pumps is up to 10 % lower.
The pump can be operated in the range between
Note
0.125 % and 100 % of the maximum dosing capacity.
The maximum display indication is higher than the
Note nominal capacity of the pump because it refers to the
default setting.
1.3.4 Accuracy
• Applies to:
– water as dosing medium
– fully deaerated dosing head
– standard pump version.
• Dosing flow fluctuation and linearity deviation: ± 1.5 % of the
full-scale value.
• Construction tolerance: according to VDMA 24284.
1.3.5 Inlet pressure and counter-pressure / suction lift during
operation
Maximum inlet pressure
Pump type
DDI 60-10 - DDI 150-4
* For pumps with pressure sensor (Flow Monitor pump option),
the inlet pressure on the suction side must not exceed 1 bar.
Minimum counter-pressure at the pump discharge valve
Pump type
DDI 60-10 - DDI 150-4
* For pumps with pressure sensor (Flow Monitor pump option),
the minimum system pressure is 2 bar and the minimum
pressure difference between the suction and discharge sides
is 2 bar. If the volume flow is not constant (as, for example, in
the case of contact or analog control), even small volume
flows should not fall below the minimum pressure or the
minimum pressure difference.

1.3.7 Enclosure class

The enclosure class is only met if the sockets are
protected! The data regarding the enclosure class
Caution
applies to pumps with correctly inserted plugs or
screwed-on caps.
• Pump with mains plug: IP65.
• Pump without mains plug: IP65 can only be ensured if the
power supply cable is connected with IP65 protection.

1.3.8 Required energy

Power supply for AC voltage
• Rated voltage range: 110-240 V.
Deviation from the rated value: ± 10 %.
• Mains frequency: 50/60 Hz.
• Maximum power consumption: 70 W including all sensors
(reduced input power according to pump type and connected
sensors).
The power supply must be electrically isolated from
Note
the signal inputs and outputs.
