| Features & Benefits |
| • The most compact gear pump series available to fit tight space constraints • High speed operation for the most economical pump option for thin to moderate viscosity applications • Vertical mounting options to further reduce the unit footprint • Flange for motor mounting bracket eliminates the need for drive equipment and provides better unit alignment (Mounts available for NEMA & IEC motors) • Behind the rotor seal, so shaft and bearings not exposed to media • NPT available on G-AL Sizes, ANSI or DIN flanges on KE-QS sizes, enabling easy in-line mounting to almost any piping system • Sealed anti-friction bearings eliminate the need for relubrication • Threaded one-piece bearing housing allows for end clearance adjustment • Gauge ports for easy application of gauges or transducers (location varies by pump size) • One-piece casing ensures alignment for maximum bearing and seal life • Expanded feeding area and redesigned head allow for higher speed on KE-QS size pumps (KE-QS pumps are CW only) • Pressure lubricated idler pin and bushing enhances pin and bushing life (AS-QS sizes) |
| General Description |
| Viking Pump 495 Series™ internal gear pump is the perfect solution for refined fuels, lube oils, rotating equipment lubrication, and more due to its high speed operation for thin to moderate viscosity applications. It can handle flows up to 115 GPM (26 m³/h). |
