What is the maximum discharge pressure allowed for liquid pumps used in LP Gas systems?

The maximum discharge pressure allowed for liquid pumps used in LP Gas systems is established primarily for safety and equipment integrity reasons. The correct pressure limit ensures that the pumps operate within a range that can safely handle the properties of liquefied petroleum gas, which can have varying behaviors under pressure and temperature conditions.

In the case of liquid pumps for LP Gas systems, the limit of 350 psig is stipulated because exceeding this pressure can potentially lead to equipment failure or unsafe conditions, including leaks or ruptures. This standard is aligned with recommendations and guidelines typically outlined in industry codes and regulations, which focus on ensuring the safe operation of equipment in environments where flammable materials are handled.

The other choices exceed the recommended safety limits for liquid pumps in LP Gas systems and could pose risks to operators and facilities. Therefore, adhering to the 350 psig limit is crucial for maintaining safety in the handling and distribution of LP Gas.
