Pump Tanks Chapter 3: Installation 12 of 36
3-7 Making Piping Connections
Piping systems vary with process application and pump tank configuration. Typical system
configurations are available in the Appendix, but the details may or may not apply to your
application. Refer to Figure 1 on page 13 for pipe sizing guidelines. Piping systems must be
designed by a person knowledgeable in piping system design and configuration. Our
contracting department can design and install a piping system tailored to your process.
All process piping returning to the pump tank must be equipped with an inverted trap with a
vacuum breaker at the high point of the system to prevent mains from siphoning into the
pump tank.
Run mains full size in order to reduce pressure drop in the system and provide maximum
pressures at the ends of the mains.
Caution! Do not support piping from the tank or from pumps. Do not weld piping or
piping supports to the tank, as epoxy coating on some tank models can be
damaged.
Caution! Customer is responsible for converting connections to metric sizes as needed.
