About this product
Liquid-lubricated, dual mechanical seals require a continuous supply of clean, cool buffer or barrier fluid. Flowserve NR Series reservoirs are ideally suited for sustaining Plan 52 unpressurized and Plan 53A pressurized operations. Available in many pre-engineered configurations or customizable to your requirements, these reservoirs are easy to install and maintain with water or other barrier/buffer fluids. NR Series reservoirs are specifically designed to meet the needs of a variety of industries, including chemical, food processing, pulp and paper, municipal water and wastewater applications.
Features and Benefits
Two convenient sizes, 7.6 L (2 gal) or 19 L (5 gal), are available for easy plant standardization.
Robust weld pad level gauge is included for at-a-glance liquid level measurement.
Water management system (optional) utilizes an air vent valve for easy automatic filling to the ideal liquid level from a plant water line and a visual flow indicator for easy identification of an inboard seal leak.
Pressure indicator accurately displays barrier/buffer pressure in the reservoir.
Optional cooling coils control the reservoir temperature by heating or cooling with water to maintain the optimum seal operating temperature.
Optional pressure switch triggers an alarm if the reservoir pressure decreases on a Plan 53A system or increases on a Plan 52 system.
Optional level switch monitors the barrier/buffer fluid level and activates a low- or high-level alarm, alerting the operator to adjust the fluid level.
Optional stand securely supports the reservoir assembly.
Reservoirs are designed in accordance with ASME VIII, Div 1 and PED.
U-stamp, PED (2014/68/EU) Cat II, CRN, SELO, AS1210 are available.
