FULLY CONFINED O-RING TEFZEL* LINING WITH DUCTILE IRON CASING Sealed to casing for zero leakage. Acid-resistant Viton standard other materials available. One-piece solid casing lined with minimum 1/8 inch (3 mm) TEFZEL*. Rotolining process assures mechanical integrity of lining. ONE-PIECE ENCLOSED IMPELLER CLAMP RING Pressure retaining...

Exceptional Performance for Chemical Services 10X More Dry Run Protection 10X More Dry Run Protection with Dryguard™ Bearings Goulds unique DryguardTM diamond-like carbon coating significantly reduces the coefficient of friction enabling periods of safe operation under dry run conditions. DryguardTM is up to 1.5X harder than silicon carbide, ensuring its protection lasts throughout the life of the pump. Power Monitors No pump is designed to run dry for an extended period of time. Goulds recommends that pumps be protected with a power monitor. Easy to install and easy to operate, power monitors...

Reliable, Simple – Easy To Maintain Design Features for Extended Pump Life Casing with TEFZEL® Lining One-piece solid ductile iron casing with Tefzel® lining. Generous lining thickness of 1/8 inch (3 mm). Rotolining process assures integrity of lining. Rugged foot mounted design provides maximum resistance to and distortion from pipe loads. Flange loads are the same as metal ANSI pumps. Casing drain allows complete evacuation of pump fluid. Radial and Thrust Bearings Multiple materials available to best suit your pumping application: Carbon, pure sintered Silicon-Carbide or Dryguard™. All rotating...

Model SP 3298 for Self-Priming Applications When suction lift conditions exist, air must be evacuated to effectively prime the pump. This air or vapor must be expelled each time the pump is started. The Goulds design incorporates a highly reliable one-piece casing without the use of an internal check valve or external gooseneck. Optimally-sized Casing Retains enough liquid to prime but not too much to increase fluid temperature during priming. Temperature rise is half of the competition. Retained Liquid Integrated suction gooseneck keeps all bearings fully submerged to ensure lubrication during...

Model V 3298 In-Line Design for Cost Savings In-Line Design for Cost Savings Vertical Configuration Vertical casing frees up additional floor space required for pump. In-line pumps have become increasingly popular due to minimal floor space required and reduced installation costs. Installation is simple since the unit is mounted directly in the line, like a valve. Field alignment is not required and the unit is not subject to misalignment due to pipe strain or temperature changes. Self-Venting Design Containment shell and magnet area expel all trapped air/gases completely and efficiently during...

Leadership in Sealless Pump Technology Model 3299 Heavy-Duty Lined Chemical Pump PFA Construction for Universal Corrosion Resistance to 360˚F (182˚C) Virgin Teflon® (PFA) is virtually inert to all chemicals and has good abrasion resistance. PFA lined casing, bearing carrier, containment shell, and one-piece impeller/shaft assembly provide superior corrosion resistance and long life, unequalled by alloy pumps. Designed for Safe Operation Dry Run Capability Standard DryguardTM Silicon Carbide Bearings Provide the corrosion resistance and durability of silicon carbide with short term dry run capability...

Leadership in Sealless Pump Technology Model 3296 EZMAG Containment Shell The containment shell is the most important component isolating the pumpage from the atmosphere. N The containment shell is a deep-drawn single piece design made from Hastelloy C for reliable corrosion resistance. N The vortex-breaking bead at the bottom of the can prevents erosion. N Burst pressure is greater than 2,175 psi. Bearing Cartridge Individual bearings are contained in a single cartridge assembly. N Bearings are made of highly abrasion and corrosion resistant silicon carbide. Dryguard™ bearings are available...
