ARBO thermoplastic, mechanically sealed centrifugal pumps are available in polypropylene, polyethylene, polyvinylidene fluoride and polytetrafluoroethylene, making them resistant to the effects of aggressive chemicals, which can cause corrosion in metallic pumps. All wetted parts are manufactured out of solid block, without the need for injection molding, which eliminates the potential for stress-cracking. ARBO pumps can handle solid particles up to 3 mm, ensuring extended pump operation in the event of process upset. The pumps are available with either close-coupled or long-coupled design. In the close-coupled configuration, ARBO pumps can be specified in either horizontal or vertical mounting options. The long-coupled, horizontal version incorporates separate frame-mounted bearing support for the motor shaft. The complete long-coupled pump unit is assembled on a rigid glass-fiber-reinforced polyester baseplate. — Michael Smith Engineers Ltd., Surrey, U.K.
