Diesel-powered cen- trifugal pumps work with clean or dirty water and can han- dle trash and fibrous materials. Electric submersible pumps have the ability to handle smaller abrasive materials and solids. Diesel-powered centrifugal pumps are great for fast dewatering on sites without an alternative power source. They are ideal for transporting or raising water with large abrasive solids in suspension. Electric submersible pumps offer portability, easy han- dling and are generally well suited to ground water control applications, including emergencies. They are also useful anywhere emissions are not allowed. Diesel-powered cen- trifugal pumps allow for continuous drainage even with significant volumes of air.

The red color is a throwback to the graphics used on the company's very first crawler tractors in 1925. Besides machines and engines, the new trade dress will be used on Cat parts packaging and various licensed products such as toys and scale models.
