The Ruhrpumpen listing should be removed from auto engine and auto engine parts since this is NOT what they do. Ruhrpumpen is a world wide manufacturer of pumps, pumping equipment, and pump parts. Their heritage products come from the former Byron Jackson and Worthington product lines.In their USA headquarters, they still have many of the original BJ employees who stayed with the company. The customer service by the parts people and their sales and application people is excellent. They are pleasant and knowlegeable.
