KB45 and KB75 Pulsation Dampener Parts: Diaphragm or Assembly?

Separate the assembly from its replacement parts

Our KB45 KB75 pulsation dampener assembly and dampener diaphragm pages cover different quotation items. A diaphragm request should identify the flexible component; an assembly request should specify which body, cover, gauge and connection components are included.

Keep KB45 and KB75 as separate model identifications. A shared product heading does not establish that their diaphragms, connections or other parts are interchangeable.

KB75 example: HHF-1300/1600 catalogue references

The Honghua HHF-1300/1600 catalogue separates the KB-75 assembly from its individual components. These entries illustrate how to write a precise order line:

The diaphragm is item 3 in that assembly drawing. Its -00 suffix belongs to the reference and should remain in the inquiry. These numbers describe this catalogue's KB-75 configuration; they do not identify a KB45 replacement or every KB75 installation.

What to send for a quotation

• Dampener manufacturer, model and a readable nameplate photo.
• Pump model, part number and the relevant assembly drawing.
• Whether you need a diaphragm, a complete assembly or individual items.
• Any documented material or connection requirement, plus the quantity of each part.
• Delivery country and destination.

If the part number is missing, mark the component on the drawing and attach photos of the existing part and its markings. We can review the available information before confirming the quotation scope.

Confirm the scope before ordering

List each requested part on its own line and check the proposed model, reference and included components. For pressure settings and maintenance procedures, use the instructions for the identified dampener; a parts list is not a charging procedure.
