Overview of Primary Product

10.
Rugged Casing Design The “1600” Series has a maximum operating pressure of 175psi, and a maximum
operating temperature of 300°F. The “1600” Series is available in cast-iron bronze fitted
construction or all bronze construction.
Cartridge Assembly Replaceable "cooler running" bearing cartridge extends bearing life, and with permanently
sealed greased lubricated ball bearings it is virtually maintenance free.
Pressure Tappings Pressure tappings allow for differential pressure readings to be taken across the pump.
One Piece Enclosed Impeller Dynamically balanced cast bronze impeller assures long life and higher pump efficiencies.
Cupro-Nickel Shaft Sleeve Non corrosive shaft sleeve protects the shaft by preventing contact between the shaft and
system fluid eliminating the need for more expensive corrosion resistant shaft materials.
Standard Mechanical Seal “1600” Series In-Line pumps utilize a “unitized” seal design which facilitates quick and easy
replacement. Available in ceramic (standard) or the new “Sealide C” (for more aggressive
system fluids) ensures the flexibility to meet a wide range of application requirements. One
size seal fits all models.
Flexible Coupler Flexible coupler absorbs shock, vibration and misalignment that could be transmitted to the
cartridge and motor bearings while also isolating and preventing any motor related noise or
vibrations from being transmitted to the system.
Resilient Mounted Motor Resilient mounted motor insures quiet reliable vibration free operation of the pump.
Parts Flexibility Superior parts flexibility: one cartridge, one seal, and two motor frames fit all pump models.
Factory Tested All “1600” series pumps are factory tested, and are built in accordance with Hydraulic
Institute Standards.
