Peristaltic Pump
•Benefits: Liquid moves continuously under pumped flow. The pump has no
metering chambers or gravity fed internal tubing to trap sediment or residual
liquid. Sample liquid contacts only the strainer, suction line, tube coupling,
pump tube, bulkhead fitting, and sample bottles.
LD90 Liquid Detector
•Non wetted Detection: Sample liquid never touches the detector.
Two Line Purges in Sampling
Cycle
The sampling cycle always includes a pre-sample purge and post-sample
purge that clears the suction line of residual liquid.
Easy Grab Samples
Simply disconnect the pump tube from the bulkhead fitting on the center
section, and place the pump tube over your sample container.
