Today, installations around the world attest to its remarkable performance. The 3185 is the heavy duty process pump designed to handle all of your tough process pumping applications. World-class Pump Line Model 3185 is built to Metric standards. ISO or JIS 16 bar flange drilling...

Goulds 3185 3 LUBRICATION FLEXIBILITY The preferred lubrication of oil is standard. No special parts required to convert to grease. STANDARD LABYRINTH OIL SEALS Prevent premature bearing failure caused by lubricant contamination and loss of lubricant. CONTINUOUS HIGH-PERFORMANCE Original high efficiency maintained by simple external impeller adjustment resulting in long term energy savings. HEAVY-DUTY SHAFT Designed for minimum deflection at maximum load. Dry shaft achieved by sealing from pumpage by O-rings at sleeve and impeller nut. RIGID FEET Large casing and bearing frame feet maintain driver...

4 Goulds 3185 It offers: 1. Ease of adjustment to maintain optimum performance 2. Clamped sideplate for maximum reliability and zero leakage 3.Minimum hydraulic loads for maximum mechanical reliability See The Difference Renewable High-performance Easy and reliable With any impeller adjustment there will be two metal components that will have to move relative to each other. Goulds puts this precision fit in the sealed and lubricated environment of the power end. Less reliable pumps utilizing adjustable sideplates are difficult to adjust, are not precise in clearances and the adjustment must take...

Clamped Sideplate For maximum reliability and zero leakage CLAMPED Our sideplate is clamped securely and sealed positively to ensure that it does not lead to breakage or leakage. FLOATING The “floating” sideplate design must scrape over a casing surface that will be corroded and fouled. This commonly leads to a leakage path through the sideplate studs. Minimum Hydraulic Loads Maximum mechanical reliability ENGINEERED FOR LONG LIFE Back vane height/angle and shroud design are engineered to minimize hydraulic loads throughout the life of the pump. Bearing life is guaranteed. As the open impeller...

6 Goulds 3185 Power End Reliability is vital when thinking about pump mean time between failure (MTBF). To ensure maximum bearing life, the 3185 follows three key bearing design factors: 1. Bearing Design Life 2. Bearing Temperature 3. Bearing Environment Power Ends Designed for Maximum Reliability Bearing design life Bearing manufacturers state that skidding, cage stresses and oil temperatures can greatly reduce the bearing life of oversized bearings. The “right” size bearing is vital to overall bearing life. Bearing temperature Keeping the pump loads minimized and selecting the “right” bearing...

8 Goulds 3185 Optimize Seal Configuration for Service and Environment How It Works: The unique flow path created by the patented Vane Particle Ejector directs solids away from the mechanical seal, not at the seal as with other tapered bore designs. And, the amount of solids entering the bore is minimized. Air and vapors are also efficiently removed. 1. Solids/liquid mixture flows toward mechanical seal/seal chamber. 2. Turbulent zone. Some solids continue to flow toward shaft. Other solids are forced back out by centrifugal force (generated by back pump-out vanes). 3. Clear liquid continues to...

9 Goulds 3185 Goulds Dynamic Seal option is ideally suited to handle the tough applications where conventional mechanical seals or packing require outside flush and/or constant, costly attention. This option allows pumping slurries without an external flush. A repeller between the stuffing box cover and impeller pumps liquid from the stuffing box while the pump is running. A diaphragm seal prevents leakage when the pump is not operating. Benefits of Goulds Dynamic Seal: External seal water not required. Elimination of pumpage contamination or product dilution. Eliminates problems and costs associated...
