KR2i / KMPi TFF Systems
Setup and Operation
1. Main Pump
Tubing Size: Select the tubing size used through the pump head. Standard Masterflex® tubing
sizes for both the KR2i and KMPi sized pumps are used.
Ramp Rate: Enter the ramp rate of the recirculation pump up to 15 sec.
Slow for Valve: If turned on the system will automatically reduce the pump speed when
pressure buildup continues to increase and the valve is fully open. This feature is typically used
when concentrating high viscosity samples. Select from 1-10% reduction in pump speed at
either %/min or %/sec.
Control Shear: If turned on the system will maintain recirculation pump speed based on
retentate shear rate/flow rate. The Flowrate display in the Main Pump section will then be
based on retentate not feed flow.
2. Aux Pump
Aux Pump 1, Aux Pump 2: Select the tubing size and the type of pump
There are three types of possible Auxiliary Pumps:
300 RPM – KR Jr
600 RPM – KR1
650 RPM – I/P Pump (only for KMPi)
NOTE: Auxiliary Pump settings must be correctly input for KR2i system to function properly.
Tubing sizes are standard Masterflex® tubing sizes and the possible tubing sizes for the
selected Aux Pump will appear in the drop down list.
