Viking Pump”s Universal Seal series pumps now support operation up to 365 M³/Hr (1,600 GPM) with the release of the RS size. The internal gear pumps can develop pressures to 14 BAR (200 PSI). They handle viscosities to 2,000,000 SSU (440,000 cSt) and fluid temperatures from -84 C to 427 C (–120 F to 800 F). Models include the RS324A (cast iron), RS323A (steel), and RS327A (316 stainless steel). The Universal Seal design allows users to select a sealing option from among cartridge seals, component mechanical seals, or packing. Seals can also be changed in the field to adjust to new operating conditions. Enlarged bearing housing provides in-line access to bearings and seals and allows easy adjustment of end clearances for continued maximum efficiency.
