KR2i / KMPi TFF Systems
Pump Head Setup and Operation
a. Manual Mode/Before Running Pump Mode:
i. First Line: Current Feed Scale weight (preceded by “F:”)
ii. Second Line: Current Permeate Scale weight (preceded by “P:”)
NOTE: If KONDUiT is present and set-points are Conductivity or UV set-points, then depending on
what KONDUiT sensors are being used the lines will display current KONDUiT readings:
Line 1 - Conductivity 1
Line 2 - Conductivity 2
Line 3 - Temperature (i.e. Temperature 1 if connected. Tempeature 2 if only the Cond/Temp 2
input is used)
Line 4 - UV 1
b. After Running Pump Mode:
i. First Line: Current
starting value
ii. Second Line: Target
set-point value
iii. Fourth Line: Current function (e.g. Conc 2, Dia 2)
Pump Head Setup and Operation
9.1 Introduction
The Easy-Load and High-Performance Pump Heads are designed to be used with the TFF systems as
a simple peristaltic pump system. The Pump Heads accept different tubing sizes for a wide range of
flow rates, and the unique designs and automatic tubing retention allow for quick tubing changes.
