Flush Water Requirements
The double mechanical seal must be flushed anytime the
mutator shaft is rotated. Failure to do this will result in
rapid seal failure due to excessive contaminate and heat
build up.
The fluid flow should be in the range of 5 to 10 gallons per
hour, at a temperature of 80°F - 120°F (25°C - 49°C).
Piping to seals should be in the bottom of head and out the
top, piped with parallel flow, never in series.
Piping
Guidelines for Piping
Refer to the general assembly drawings in this manual for
jacket connection sizes and locations, and suggested
media piping drawings.
• Support ALL piping independently.
• Provide for line expansion and contraction.
• Install a safety valve to protect jacket.
CAUTION: The safety valve should be installed
on the discharge side of product pump for safety
and equipment protection.
DANGER: Do not install any positive shutoff
valves downstream of the Votator II unit.
WARNING: Do not allow a volume of liquid to
become isolated in the jacket without relief
protection. Thermal expansion created as liquid
warms can generate enough force to crush tube,
causing damage to internal components and drive
system.
• Provide temperature indicators on both sides of
Votator II unit.
• Provide pressure gauge on discharge side of pump.
• When using liquid coolant, provide a method to
introduce heating media into jacket to thaw
overcooled product.
• Provide liquid coolant system bypass line around unit
to allow coolant system to be brought down to
operating temperature without circulating coolant
through jacket.
