efficiency. Dual mechanical seals with moisture protection system. Air
filled motor with 416 SS motor shaft, and dry run capability. All of
these features contribute to making this one of the most durable long
lasting sewage pumps available on the market today. Flow rates

continuous duty rated and are available in three phase only. Available
in 200, 230 or 460 volt with 25’ cord standard.
Moisture protection system consists of two
wire, dual moisture sensing probes located in the oil chamber between the
inner and outer seals. If the outer seal fails and allows water into
the chamber the probe senses that and sends a signal to your control panel.
(Must have alarm circuit on panel to operate) it will also detect moisture
before it reaches the bearing or stator to protect them from damage.
