The RS Series
The RS is our new process duty, horizontal ring section multi-stage pump. Designed for moderate to high pressure pumping, the RS is available in five basic sizes with overall performance to 1,000 HP.
The RS is offered with ANSI 300 lb. Inlet flanges and ANSI 600 or 900 lb. discharge flanges, depending on the pressures and number of stages involved. Either way, hydraulic performance extends to 1,400 GPM and 3,400 ft. TDH, which surpasses that of all comparable pump types and makes it ideally suited for the most demanding industrial and process services. The RS design incorporates a product lubricated radial bearing as standard. The thrust bearings are two matched angular contact ball bearings located at the inboard (suction) end of the pump with a product lubricated, composite material with Moly/PTFE additives sleeve type radial bearing at the outboard (discharge) end. For units with an optional outboard mechanical seal, the angular contact ball bearings move to the outboard end and a ball bearing is added at the inboard end for handling any radial loads.
The RS also offers the choice of either grease or oil lubricated thrust bearings. The greased
bearings are the regreasable type, and the oil lubricated bearings include a further option of external water cooling for high temperature operation. Many other options and arrangements, such as turbine and magnetic drive units, are also available. These options, together with all the value-added features shown on the following pages, offer the benefits of:
• maximum safety
• maximum installation flexibility
• maximum fluid compatibility
• higher efficiencies
• longer component life
• minimal down time
