Adding an external drain pump to washer

Hi everyone,

I have a washer located in the basement, and the lift from the machine to the drain outlet is about 8 feet. I'm concerned that this is hard on the machines internal pump, and want to add an external pump that would help with the lift. Can anyone suggest what type of pump I need and where I would find one? Anyone had any experience with this type of pump, if so I'd like to hear whether it works efficiently?

Thanks
