Page 19: Soft Foot
Installation SOFT FOOT Soft foot is a condition in which one of the pump feet does not sit flat on the base. Soft foot is usually due to irregularities in the surface to which the pump is mounted. When the bolt on the foot gets tightened, a slight distortion occurs that can affect bearing and seal life as well as cause internal contact between parts. -
Page 20: Operation
OPERATION STARTING THE PUMP CAUTION If the pump has been idle for an extended period of Standard pumps with stainless steel time, turn the pump by hand prior to energizing the impellers (designated with material codes F motor to determine that the impeller is free to turn. or C) are suitable for operation with sealant temperatures up to 160°F (71°C). -
Page 21: Initial Start-Up
Operation INITIAL START-UP 5. A liquid level gauge is installed to allow visual monitoring of the sealant level. NOTE: The limitations on what sealant can be used in the 1. Turn on the main power by closing the external liquid ring pump are based on the following fusible disconnect switch or circuit breaker. -
Page 22: Stopping The Pump
Operation A loud rumbling sound is a sign that cavitation is occurring. It is easily suppressed by raising the inlet pressure above the vapor pressure of the sealant at its operating temperature by bleeding air or another comparable gas into the suction if opening the attentuation valve cannot be used or does not bleed in enough air. -

Page 24: Preparation For Storage
Maintenance PREPARATION FOR STORAGE If the pump is to be idle for an extended period of time, it should be preserved internally to prevent rust if the sealant liquid is water or water-soluble liquids. The pump can be preserved temporarily (2 to 3 months) by adding a water-soluble rust inhibitor into the pump. -
