Liquid line piping
Liquid line piping
An Nippon pillar packing Super 300 type 1-¼" union nut/sleeve is originally equipped to the
inlet of the pump and that of 1" union nut/sleeve to the outlet of the pump. Use an applicable
tube of O.D. 31.8mm × I.D. 28mm to the inlet and that of O.D. 25.4mm × I.D. 22.2mm to the
outlet for the connection between the pump and your piping system.
*
Select an appropriate tube fitting size. Both discharge- and suction-line I.D. should be larger than the pump outlet & inlet
I.D.
* General joints can be used, however, no leakage is allowed under hot liquid transfer or heat cycle.
NOTE
Use measures to keep the pump connections free from stress.
Points to be observed
Air blow or flush a suction and a discharge tube to get rid of debris prior to connecting
with the pump.
Connect a suction and a discharge tube to the pump inlet and outlet via the tube fittings.
Use measures to keep the pump connections free from stress such as weight and thermal expansion/
contraction.
NOTE
Be sure to secure each connection to prevent leakage and air ingress.
