I received one of the pumps that I ordered today.

It is marketed under the brand name URO Parts.

from A.P.A. Industires in Simi Valley, California.

Looks just like the pump pictured on the eBay seller's link above.

There's isn't any label or printing on the pump itself.

I have just replaced the strainers, so I'll see if I even need the pumps.
