This is very basic for YOU. Please try to remember that not all the readers here are engineers. Myself for example have no formal education in engineering but have had to aquaint myself with many of its aspects due to the job I do. It was here that I learned so many of the things I needed. I can now discuss confidently with my clients the differences between positive displacement and centrifugal pumps. Reciprocating or rotary. OK I'm still out at sea when the tariff gets to "single stage, single suction, frame mounted centrifugal pump with discharge outlet 5.08 cm or over." Yes that is an actual description from the tariff in Canada (8413.70.10.14) and it was CR4 that taught me the difference between "frame mounted" and "close coupled"

So please have patience with us non-engineer types when our questions seem basic to you. I mean if it was so basic, couldn't you have answered the question in about the same amount of time it took you to post what you did?

The word drain pump is used by many products and it may confuse.

A washing machine uses a drain pump to empty the bowl.

A inline sewage pump is also called a drain pump.

A pump to de-water a flooded cellar or a tank is also called a drain pump.

A sump pump is also a drain pump but usually more permanent.

a sump is made at the lowest point to gather the water which is then pump out under control of float switches.

Pumps are given names based on two primary catagories.

These are:

"Type" and "Function"

- "Types" includes: Centrifugal, Reciprocating, Diaphram, Continuous Cavity, Screw, etc

- "Function" includes: Feed Pump, Bottoms Out Pump, Product Transfer Pump, Boiler Feed Water Pump, Fire Water Pump, Sewage Pump, Drain Pump, Sump Pump, Vacuum Bottoms Pump, Loading Pump, etc

It depends on the capacity and the design conditions (pressure/temperature), but for most of the functions you can use any of the pump types.

Quick and dirty - a sump pump will almost always be an immersible pump mounted at the bottom of the sump. A drain pump can be (but is not always) a non-immersible pump mounted outside the area/thing to be drained.

Rule of thumb: if it has an inlet hose, it's a drain pump. If the inlet is an opening at the base of the pump (no hose, no threads for one) you'vve got a sump pump.

Both types will generally have strainers of some sort.

Hope this helps.
