Motor-driven Piston
KARDOS ZN
Duplex KARDOS N piston dosing pump with two opposed heads
The KARDOS ZN is the duplex version of the high-pressure KARDOS N piston dosing pump, with the dosing heads arranged opposite each other on a common drive. Each head is 100% adjustable independently; a speed change of the main drive acts on both heads so that the volume ratio between them is maintained.
Head, valve, packing and connection options are the same as for the KARDOS N: stainless steel heads for up to 400 bar and plastic heads for up to 10 bar, pistons in ceramic or stainless steel, packings in PTFE or aramid-kevlar. Stroke adjustment is manual or by electrical servomotor (ATE).
