BUYER CHECK

Before this model goes on a purchase order

Confirm fluid temperature, glycol percentage and speed control. TD is a crowded series name—use the CNP model index, not a generic TD table.

  • 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.
