K CL PLUS
K PLUS is a constant or proportional dosing pump with level control for chemical feeding into water.
In Constant dosing mode pump doses a constant quantity regularly as configured by the user.
In Proportional dosing mode pump doses a quantity proportionally to an input signal, digital (voltage
free contact) or current (mA).
Working modes available:
• constant
• constant with 1-10 pulses divider
• multiplier with 1-10 pulses divider
• divider with 1-10 pulses divider
• divider with 1-100 pulses divider
• divider with 1-1000 pulses divider
• mA current signal (0/4 mA = 0 pulses: 20mA = max pulses)
Flow rate is determined by the stroke length and by the stroke speed. The stroke length is adjustable
from 0 to 100% using the stroke length adjustment knob. However dosing accuracy is guarantee
within an adjustment range from 30% to 100%.
K CO PLUS works in constant mode.
The pump can be set to work in
• constant
• constant with 1-10 speed reducer.
K CL PLUS works in constant mode and has got level control.
