The 3500 series is well suited for pumping high volumes of heavy slurries that are abrasive, corrosive, or just plain tough to pump.  The 3500 series can deliver flow rates up to 7500 GPM and head pressure up to 540 feet.  The compact overall dimensions of the 3500 series make it an excellent choice for high volume mobile and stationary applications where a small footprint is critical.  The 3500 series is designed for continuous operation with minimal maitenance.  The low stuffing box pressure and extra-heavy shaft design are engineered to provide maximum seal life.  The unique casing flow divider cuts the raidial load in half, doubling bearing life.  The heavy-duty bearings are permanently lubricated to minimize maintenance.
