Description of the Binary Solvent Delivery Module
The system consists of two Series III high performance metering
pumps, in a compact package with pulse dampener and an off-line
pressure transducer. The pumps use a drawer system for easy access to
internal components for troubleshooting & service. These features
allow for:
f
Fast & easy setup:
Two inlet connection (from solvent reservoirs)
One outlet connection (to injector)
All connections accessible from front panel
f
Modular:
Can be added to any system
f
All Stainless steel or PEEK Fluid path, including pumps, valves
and fittings
f
Modular pump bays for easy replacement and maintenance
f
Self flushing pump heads for extended seal life and reduced
maintenance
f
Pulse Dampener for reduced pulsation.
f
Very high performance/price ratio
f
Easily user adjustable process set points (flow rate, pressure. etc.)
via front key pads
f
Digital readout of process parameters
f
User settable upper/lower pressure and temperature limits
f
RS-232 serial PC interface
f
Compact size—Requires only 11 inches of bench space
The low pulsation flow produced by the reciprocating, single-
piston pump is achieved by using an advanced rapid-refill cam design,
programmed stepper motor acceleration, and an internal pulse damper.

Features
They include:
•
Rapid refill mechanism to reduce pulsation
•
Stainless Steel or PEEK™ pumps head
•
LED front panel readout of flow rate, pressure and upper/lower
pressure limits
•
Flow adjustment in 0.001 ml increments, from 0.001 to 5.000
ml/min with a precision of 0.2% RSD (5mL/min heads)
