Dual Head Constant Pressure Pumps
A New Way to Pack Columns with Reduced Shear for Greater Efficiency
SSI now offers a full line of electric dual-head, constant
pressure pumps for a wide range of column packing
applications. These pumps offer the complete range of
control and pressure options for packing new small
particles (1-micron – 10-micron) and soft, pressure
sensitive polymeric materials.
 0.01 – 12.00 or 0.01 – 24.00 ml/min flow rate
Packing process advantages include:
 316 Stainless Steel fluid path
 18,000 or 10,000 p.s.i. upper pressure limit (across the
flow range)
 Dual ball and seat check valves (ruby ball, sapphire
seat)
 8,000 p.s.i. max pressure capability
 Prime-Purge Valve
 Increased plate counts by up to 20%
 Higher yields
 Front keypad control, w/LED display (pressure, flow, set
points, etc.)
 The ability to pack ultra-small particles with consistent bed density
 RS-232 Serial com port for PC interface
 Control of pressure to effectively pack soft polymeric materials
 USB Connectivity (Integrated USB to RS-232 Solution)
 Full PC control with software (included) - save methods,
pressure/flow control, monitor & save pressure/flow data
 User Controls & Set-Ups
 Set Desired Pressure (pump flow rate automatically adjusts)
Specifications
 Set Ramp Rate (adjusts rate of change in auto-flow adjustment)
 Conventional Electric Pump (110-Volt or 220-volt input)
 Set Upper Flow Rate Limit
 Constant Pressure control mode for column packing
applications
 Dual pump heads, cam-driven with single stepper motor
drive
 PC control software included: Develop & save methods,
control flow & pressure via RS-232, monitor & save
packing process data

Dual Head Constant Pressure Pumps
Column Packing System
Ordering Information
SSI’s column packing reservoir system is specifically
designed to provide fast, versatile, safe packing of
efficient, reproducible columns. An internal baffle prevents
the inlet flow stream from impinging directly on the slurry
in the reservoir. A conical outlet section promotes smooth
transfer of the slurry to the column. The quick-changed
threaded reservoir closures help avoid slurry-settling
problems and promote more reproducible packings.
Description
The modular design allows fast interchange of reservoir
housings and column connectors. Knurled closure nuts
and Kalrez® seals combine to allow fast, leak-tight
changes to be made by hand – no tools required. The
column couplings are drilled to allow direct contact of the
column to a pre-column of the same diameter. This allows
the columns to be removed without disturbing the packing
bed.
