Installation

Piping

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.

Flush Fluid Requirements

The double mechanical seal must be flushed, using the
threaded flush ports, anytime the mutator shaft is rotated. Failure
to do this will result in rapid seal failure due to excessive
contaminate and heat buildup.
The fluid flow should be in the range of 5 to 10 gallons per hour,
at a typical temperature of 80°F - 120°F (25°C - 49°C). Fluid
composition and temperature should be selected to dissolve or
suspend any product leakage and cool the mechanical seal
faces, and should also be compatible with the sealing o-ring
material. Piping to seal cavities for horizontal units should be in
the bottom of head and out the top, piped with parallel flow, never
with multiple seal cavities in series flow.

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.
• 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.
The steam solenoid is opened, which lets pressure controlled
steam from the boiler into the jacket. A temperature sensor
monitors the temperature of the product and regulates the steam
flow to achieve the required temperature. Heating of the product
takes place when the steam condenses into water from the
transfer of heat through the jacket.
