Is it sufficient to meet the applicable standards when purchasing a centrifugal pump?

I’ve only been in this industry for a short time, and the technical agreements I prepare are indeed based directly on the procurement standards. I’m not sure how the more experienced colleagues handle technical agreements

When purchasing a centrifugal pump, first select the appropriate material based on the medium you will be using. Next, decide on the flange standard; the national standard is usually used by default, but special requirements can be discussed with the manufacturer. Finally, choose the model according to the flow rate and head requirements.

• 8.3.4 Optional Tests

•In API685, some inspections are optional. Among these optional inspections, factors such as the type of medium, head, pressure, temperature, or the structure or other conditions determine which inspections should be carried out For example, under what circumstances should these options be included for hot water pumps? Please share your thoughts freely When specified, the shop tests described in 8.3.4.1 through 8.3.4.7 shall be performed. Test details shall be mutually agreed upon by the purchaser and the vendor. • 8.3.4.1 NPSHR Test 8.3.4.1.1 NPSHR data shall be taken at each test point (4.3.3.2.1) except shut-off. 8.3.4.1.2 A 3 percent drop in head shall be interpreted as indicating performance impairment. 8.3.4.1.3 NPSHR at the rated point shall not exceed the quoted value (see Table 7). Dismantling to correct NPSHR requires a retest (see 8.3.3.4.2). • 8.3.4.2 Complete-Unit Test Such components as pumps, drivers, and auxiliaries that make up a complete unit shall be tested together. The complete-unit test shall be performed in place of or in addition to separate tests of individual components specified by the purchaser. • 8.3.4.3 Sound-Level Test Sound level tests shall be performed as agreed between the purchaser and the vendor. Note: ISO Standards 3740, 3744, and 3746 may be consulted for guidance. • 8.3.4.4 Auxiliary-Equipment Test Auxiliary equipment such as control systems shall be tested in the vendor’s shop. Details of the auxiliary-equipment test shall be developed jointly by the purchaser and the vendor. • 8.3.4.5 Secondary Containment/Control System Hydrotest When specified, the pressure integrity of the secondary containment system or secondary control system shall be verified by hydrotest using the same criteria as the pressure casing (Reference 8.3.2). Certification shall be provided by the vendor. • 8.3.4.6 Secondary Containment/Control System Instrumentation Test When specified, the operability of the instrumentation supplied with the secondary containment system or secondary control system shall be verified. Criteria for the test will be mutually agreed to by the purchaser and the vendor. Certifications shall be provided by the vendor. • 8.3.4.7 Pressure-Temperature Profile Test When specified, the vendor shall demonstrate the pressure-temperature profile in the recirculation circuit using a fully instrumented pump unit of similar design to the specified unit. Pressures and temperatures at critical points in the circuit shall be measured with the unit pumping water. A pressure-temperature profile shall be developed as defined in Appendix G, with data factored to correspond with the specified fluid and service conditions. Criteria for the test and data presentation shall be agreed to by the purchaser and vendor.

It depends on what type of pump you produce; I’m not very familiar with water pumps. Most chemical centrifugal pumps meet the requirements specified in API610, which outlines clear guidelines for the design, manufacturing, and testing of such pumps
