Laundry tub pump problem

[rennyboy]

I have a basement where my washer and dryer are along with the heating unit. There is a laundry tub that the washer water dumps into and the water from the ac and humidifier. The main sewer is about 6 ft higher than the tub. The drain line of the tub has a pump connected underneath it that looks a little like an old style tea kettle, it's part cast iron and shuts off and turns on at certain levels of water. The water than flows from a pipe connected to it up to the sewer. Lately it has been going out very very slowly. I snaked out the sewer but noticed that the water going out was not pumping up fast at all. The water in the tub has a nice whirlpool like as if it was going fast, but it seems like it is just spinning. Anyone have any solutions for me or where I can purchase another pump like this and about what it would cost for the pump? I have not seen any of these in the local supply stores. Thanks in advance for any and all help

I am going to take and post a pic of the pump for future use. The problem wasn't the pump after all. The pvc line going from the tub to the main was full of lint and crud, removed the pvc and replace w/new pvc and new check valve and all working good.
