SERIES 8124A (Cast Iron) 8123A (Steel External) 8127A (Stainless Steel) Heavy-Duty, Foot-Mounted Sealless Internal Gear Pumps Operating Range①: Cast Iron Series 8124A Nominal Flow Pressure Range Temp. Range ② Model H8124A Viscosity Range Steel Externals Series 8123A Nominal Flow Pressure Range The Universal Mag Drive is the ideal sealing technology within Viking’s Universal Seal Series of pumps. It is dimensionally interchangeable with Viking bracket styled heavy duty and Universal Seal pumps, allowing an easy upgrade from packed or mechanical seals to sealless technology. The Universal Mag Drive’s hermetic, static sealed canister provides the highest level of liquid containment available by eliminating traditional dynamic shaft seals. It also eliminates housekeeping issues and downtime due to seal failure. This product is designed to handle a broad range of applications requiring continuous duty at pressures up to 200 PSI (14 Bar). Stainless Steel Series 8127A Nominal Flow Rates: Nominal Flow Viscosity Range Pressure Range Viscosity Range ① Refer to Specification Tables 635.7 for individual model information. ② Samarium cobalt magnets required for temperatures over 225° F (107°C) VIKING PUMP • A Unit of IDEX Corporation • Cedar Falls, IA
