- Semi-vortex urethane Rubber impeller with suspends solids and allows for pumping of sand and stringy material hightly efficient, continuous duty air filler, copper wound motor with class F, insulation minimizes the cost of operation.
- Built in Thermal protection prevents motor failure due to overloading, accidental run-dry and single phasing or three phase units.
- Double inside mechanical seals running in an oil filled chamber provide for one the most durable seal designs available.
- Double shielded, permanently lubricated, high temperature C3 ball bearing rated for a B-10 life or 60,000 hours provide for extend operational life.
and agitator impeller is provided on the extension of the pump shaft. This not only prevents " air locking" which is caused by air building up inside the casing, but also reduces clogging when solid objects are sucked in.
