Piping - BeaconMedaes Lifeline Camel Installation, Operation And Maintenance Manual

"Camel" Liquid Ring Medical Vacuum

1.5 Piping

Connect piping to the system so that no strain is applied at the point of connection. Pipe strain on vacuum pump
castings may cause hard-to-trace troubles after the system is in operation. Support inlet and discharge piping near
the system. Allow for expansion and flexibility in those cases in which rigid piping is used in order to prevent strain
from pipe expansion, bending and twisting forces. Use the provided flexible piping connections at the inlet,
discharge and seal water lines as well as the resilient mounts when installing the system. Remove any foreign matter
from piping by flushing the piping before connecting it to the system. After piping connections are made, check to
make certain that the vacuum pump can be turned over freely by hand.
1.5.1 Intake Piping
Before connecting any piping, the plastic thread protector installed in the connection port must be removed. Connect
the vacuum system piping to the inlet connection. Refer to the drawing(s) supplied with your system and NFPA 99
for specific piping requirements. The main vacuum line to the receiver must never be reduced below that
provided on the receiver. Long piping runs may need to be increased in size to minimize pressure drop. Improper
line sizing may result in a loss of capacity. Ideally, piping should be constructed using long radius elbows and a
minimum number of turns.
All intake vacuum lines must be piped to in accordance with NFPA 99. Ensure that no restriction of airflow will
occur. All piping must be either seamless copper tubing or other corrosion-resistant metallic tubing, such as
galvanized steel or stainless steel, as detailed in NFPA 99.
1.5.2 Seal Water Piping
Connect the seal water supply to the seal water line dielectric union. Refer to the drawing(s) supplied with your
system and NFPA 99 for specific piping requirements. Seal water piping connections must satisfy the following
requirements:
a. Flow rate per vacuum pump shall be as specified in the table below
b. Minimum seal water supply pressure shall be 25-psig. If a 25-psig supply is not available, contact
your BeaconMedæs Representative for an alternative.
c. The seal water shall be non-corrosive to system materials. Make certain that the seal water meets the
following requirements:
1.5.3 Drain Piping
Connect pipe to the seal water drain connection. Refer to the drawing(s) supplied with your system. The seal water
drain line should flow by gravity to a suitable drain with an air break at the drain point. The drain loop is vented.
