The Jebao SDW pumps are a new pump from Jebao, and include an updated sine wave control signal that vastly improves the lifespan of the pump motors.
There are 5 wave modes, as well as a built in master/slave function, feed timer and night mode. The controller can also be locked to prevent unwanted changes.
The modes are as follows:
W1: Wave Mode
W2: Sine Wave Mode, pump pulses between 30% and 100% in a sine wave pattern
Else: Random flow pattern- note flow can not be adjusted in this mode
H: Constant flow mode
C: Anti-sync pulse- 2 or more pumps in master/slave mode required
The SDW-16 has a maximum output of 4,250gph, and measures 3″ long with a 2.5″ diameter. The outer magnet works on glass up to 5/8″.
