- 316 stainless steel, PEEK and Hastelloy-C options
- 0-5 VDC, 4-20 mA and RS232 control
Eldex Optos Series pumps are designed for accurate, dependable fluid metering in demanding industrial and laboratory applications. Built for processes that require precise flow control at elevated pressures, they provide reliable continuous operation while helping to minimise maintenance requirements and unplanned downtime.
The Optos Series is available in three configurable pump models, with a choice of low, standard and high-flow liquid ends to suit different flow-rate and pressure requirements. Selecting a configuration that normally operates within the upper half of its specified flow range will generally provide the most efficient pump performance.
