BUYER CHECK
Before this model goes on a purchase order
Ask for the Kaiquan curve revision, NPSH, motor efficiency class and flange standard. Do not treat KQW as interchangeable with other ISW-style names.
- Ask the bidder to mark your exact duty point on its issued Q-H curve.
- Confirm wetted-part material, seal faces and elastomer by line item.
- Put test standard, tolerance and witness requirements in the order.
