Q. "What's the difference between an automatic and non-automatic pump?"
A. An automatic pump has a built in float switch that will turn on the pump automatically at a fixed water level. After the water is pumped out to certain water level (also a preset level), the pump will turn itself off. A non-automatic pump has to be manually turned on and off, or with a separate control like a piggyback float switch.
Q. "What is a vortex impeller and what does it do?"
A. A vortex impeller handles debris better than other impellers. It's used to help prevent clogging in your pump. Below is an example of a vortex impeller.
Q. "What does the automatic reset thermal overload protection do?"
A. If the pump gets too hot the thermal overload protection will turn it off until the pump cools down (to prevent damage to the motor). The pump turns back on after it has cooled down enough. This backup protection feature is useful if some debris causes the pump to overheat.
Q. "What's the advantage of a double seal over a single seal pump?"
A. The inside seal provides added protection in case the primary seal should ever fail.
Q. "What kind of material is 'neoprene'?"
A. Neoprene is a high grade synthetic rubber with these features:
Q. "What is the difference between a sewage ejector pump and a grinder pump?"
A. A sewage ejector pump has impellers that enable the pump to pass a predetermined size of solid matter without clogging the discharge. A grinder pump has cutter blades that macerate and shear waste solids and items not normally found in sewage, but may get flushed down the toilet. These smaller particles can then be passed through the pump impellers out the discharge.
