YL9112 Isocratic Pump
plunger, check valve, high pressure seal, low pressure seal and rinsing port. YL9112 isocratic pump built
in automatic rinsing port to clean the head assembly efficiently if uses buffer solution.
•
Auto Rinsing Pump
Auto rinsing pump delivers cleaning solvent from the rinsing solvent bottle to the inside of pump head.
YL9112 isocratic pump rinse the system every 3 minutes automatically.
•
Prime/purge valve
This valve is used for priming the pump. Fill the solvent inside of tubing from the solvent bottle if you use
the pump for the first time or the tubing lines are empty. Remove a plug on the prime/purge valve and
suck the solvent using syringe, or click “Prime Start” button on the software to operate the micro pump.
•
Prime micro pump
Using this pump, the pump circulates rinse solvent into the pump head.
•
Mixer
It is static mixer to improve mixing efficiency of solvent.
•
Pulse damper
YL9112 isocratic pump reduces pulse from the cam operation by the diaphragm damper. YL9112
isocratic pump provides constant and pulseless flow using compressibility compensation and pulse
damper, so the detector that affected by flow stability can be used with YL9112 pump.
•
Pressure transducer
It checks real time system pressure. The pump uses this pressure to protect system and to operate
compressibility compensation and even compensation. YL9112 isocratic pump uses continuous flow
path type pressure sensor.
•
In-line filter
It removes fine particles that are not filtered by solvent filter or made by worn of high pressure seal.
