Brief Descprition Of Problem

Preliminary Information
Is the boiler steam plant pressure steady and not fluctuating for the supplied steam to this evaporator?
Is your air ejector condenser vent line steadily venting steam to the atmosphere? A slight "puffing" of steam is normal.
Are any the evaporator systems high or flooded, such as Flash Chambers, Distillate Sight Glasses, or Feed Water Heater Sight Glasses?
Are any of the pump mechanical seals leaking fluid or pulling a suction from the atmosphere, such as Distillate Pump, Condensate Pump, or/and Brine Pump?
Pumps that have packing glands and packing strands, in lieu of mechanical seals, are designed for a slight leak off rate of 20 to 40 drops per minute.
Is pump leak off rate 20 to 40 drops per minute?
Is the packing gland dead ended to the pump casing body?
Is the packing gland allowing air to be sucked back into the pump body cavity?
When was the last time the Feed Water Heater Tubes were cleaned?
