SSI America 90-2581 REV B manual Pump Features, fFast & easy setup

1.1Description 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:

fFast & easy setup:

„Two inlet connection (from solvent reservoirs)

„One outlet connection (to injector)

All connections accessible from front panel

fModular:

„Can be added to any system

fAll Stainless steel or PEEK Fluid path, including pumps, valves and fittings

fModular pump bays for easy replacement and maintenance

fSelf flushing pump heads for extended seal life and reduced maintenance

fPulse Dampener for reduced pulsation.

fVery high performance/price ratio

fEasily user adjustable process set points (flow rate, pressure. etc.) via front key pads

fDigital readout of process parameters

fUser settable upper/lower pressure and temperature limits

fRS-232 serial PC interface

fCompact 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.

1.1.1 Pump 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)
