Miniature Submersible Pump
SBE 5M

Print version     Configuration options & accessories

DESCRIPTION

The SBE 5M pump module consists of a centrifugal pump head and a long-life, DC, ball-bearing motor contained in a compact, titanium pressure housing usable to 10,500 meters (34,400 ft) deep. A plastic housing for depths to 600 meters (1960 ft) is available as an option. The pump impeller and electric drive motor are coupled magnetically through the housing, providing high reliability by eliminating moving seals. Motor speed and pumping rate remain constant over the entire input voltage range. The motor drive electronics is intrinsically protected against accidental reversed polarity.

APPLICATIONS

The SBE 5M is standard on the 19plus V2 SeaCAT Profiler CTD, and is optional on the SBE 16plus V2 and 16plus-IM V2 SeaCAT C-T Recorders. The pump flushes water through the conductivity cell at a constant rate, independent of the CTD's motion, improving dynamic performance. For applications requiring pumping through additional sensors (for example, a dissolved oxygen sensor), use the SBE 5T or 5P pump instead.

Specify:

• Option 5M-1 for profiling (continuous duty) applications such as the SBE 19plus V2.
• Option 5M-2 for moored (pulsed duty) applications such as the SBE 16plus V2 or 16plus-IM V2.
