Platinum/Optima CVE Refrigerated Sampler
5.4 Compressor/Vacuum Pump
Each sampling system is equipped with one
continuous-duty, permanently lubricated,
piston or diaphragm compressor/vacuum
pumps that provide long-term consistent
sampling with vertical lifts of up to 28 feet (US
23 ft. lift standard). These pumps need no
routine maintenance.
The pump and its 4-way solenoid valve are
mounted on a metal plate behind the sampler's
upper rear access panel. If your pump's
performance declines unacceptably,
replacement pumps and service/rebuild kits
(including instructions) can be obtained from
Teledyne ISCO.
