Viking Pump TSM230: Hygienic Series - Manual (Page 3)

SECTION TSM 230 ISSUE B PAGE 3 OF 15
SPECIAL INFORMATION
PRESSURE RELIEF:
1. Hygienic Series pumps are not available with an integral
pressure relief valve.
2. Viking pumps are positive displacement pumps and
must be provided with some sort of pressure protection.
This may be an inline pressure relief valve, a torque
limiting device, or a rupture disk.
3. If pump rotation is to be reversed during operation,
pressure protection must be provided on both sides
of pump.
For additional information on pressure relief valves, refer
to Technical Service Manual TSM000 and Engineering
Service Bulletin ESB-31.
METAL DETECTABLE COMPOSITE IDLERS:
1. Minimum detection limits will vary depending on individual
customers’ equipment and operating conditions.
2. Viking is not responsible for failure to detect components
due to detector limitations and/or detector malfunctions.
Refer to the metal detector manufacturer’s design
limitations, instructions, and warnings regarding the use,
limitations, and proper maintenance of the equipment.
TEMPERATURE LIMITATIONS:
The standard Hygienic Series pumps have a maximum
temperature limit of 225°F (107°C). Pumps with optional
PEEK and Acetal idlers are limited to 200°F (93°C) and
125°F (52°C), respectively. Ensure that the temperature of
the process liquid, cleaning fluid, and jacketing media does
not exceed these temperature limits.
JACKETING:
On pumps with jacketed features, the maximum pressure
limit for the jacketing is 225 psi. The maximum allowable
temperature for the jacketing follows the guidelines of the
temperature limitations section.
MAINTENANCE
Hygienic Series pumps are designed for long, trouble-free
service life under a wide variety of application conditions
with a minimum of maintenance. The points listed below will
help provide long service life.
LUBRICATION:
No external lubrication is required. The H-LS Hygienic Series
uses “Sealed for Life” bearings that use food grade grease
with seals on both sides.
CLEANING PUMP:
Keep the pump as clean as possible. This will facilitate
inspection, adjustment and repair work. Avoid spraying water
or cleaning fluid directly at bearing housing.
STORAGE:
If the pump is not required for immediate installation, it should
be stored in a clean, dry environment. It is recommended
that storage temperature should be between 14°F and 105°F
(–10° and 40°C).
SUGGESTED REPAIR TOOLS:
The following tools must be available to properly repair
Hygienic Series pumps. These tools are in addition to
standard mechanics’ tools such as pliers, screwdrivers, etc.
Most of the items can be obtained from an industrial supply
house.

DANGER !
Before opening any Viking pump liquid chamber
(pumping chamber, reservoir, etc.) Be sure:
1. That any pressure in the chamber has been
completely vented through the suction or
discharge lines or other appropriate openings
or connections.
2. That the driving means (motor, turbine, engine,
etc.) has been “locked out” or made non-
operational so that it cannot be started while
work is being done on pump.
3. That you know what liquid the pump has
been handling and the precautions necessary
to safely handle the liquid. Obtain a material
safety data sheet (MSDS) for the liquid to be
sure these precautions are understood.
Failure to follow above listed precautionary
measures may result in serious injury or death.
