V3.0
Oscillating positive displacement pump with electric drive, mechanical
diaphragm deflection, and constant stroke length.
Following reduction of the motor speed by a worm gear, the rotation of the
drive is converted into the suction and compression movement of the
diaphragm by means of an eccentric and tappet. A defined volume (stroke
volume) of the dosed medium is thus sucked into the dosing head via the
suction valve, and displaced into the dosing line by the pressure valve.
The dosing rate can be adjusted in the range 1:10 if a frequency converter
is fitted.
Switch on the mains power.
Switch off the mains power.
The dosing rate can only be adjusted in the range 1:10 if the frequency
converter is fitted.Diaphragm Dosing Pump
Refer to Operation Manual of the frequency converter!
WARNING
!
Settings in conjunction with GRUNDFOS dosing pumps
Please observe especially the following parameters of the frequency converter:
P013 (maximum motor frequency):
Set to maximum 100 Hz.
Due to this setting, the maximum stroke frequency of the pump cannot be
exceeded.
P086 (motor current limit):
Do not change the default setting (150%).
The motor is protected by a PTC resistor. Therefore, this parameter is not
necessary.
P081 - P 085 (motor data)
Please set this parameters to the values indicated on the type plate of the
motor.
