Product Details

Geometry to Confirm Check the overall profile, locating surfaces, stationary-seat fit, shaft fit and working length.
Hole Arrangement Compare hole positions and relevant dimensions with the actual mating component; three holes alone do not establish a match.

Material and Service Specify the pumped liquid and operating conditions; verify the supplied material combination before ordering.

Product Description

Hong Teng supplies this stamped-type three-hole mechanical seal for selected CNP pump replacement applications. The metal-component construction identifies this version and distinguishes it from the conventional machined / turned type listed separately.

When requesting this version, include a close-up of the stamped construction together with the complete removed assembly. The reference photos and measured dimensions should describe the same seal, including its stationary seat and installation position.

Use the stamped designation to specify the construction you need, not as a claim of interchangeability or a performance rating. The supplied size and material specification should be confirmed for the actual pump service.

For the other construction, compare the Machined-Type Three-Hole Mechanical Seal for Selected CNP Pumps. These are separate product variants; do not approve substitution solely because both have a three-hole arrangement.

Browse Replacement Mechanical Seals for CNP Pumps for other CNP applications. For an unidentified seal, use How to Identify the Correct Mechanical Seal for a Pump before requesting a replacement.

Application

Application and Variant Selection

This page covers the stamped-construction version for selected CNP pumps. Use it for a replacement inquiry when the existing seal, mating components and confirmed dimensions correspond to this construction. The CNP brand name alone is not a fitment specification.

What to Send for a Stamped-Type Inquiry

Send the pump nameplate, complete pump model, photos of the old seal from both sides, a close-up of the stamped metal components, and a clear image of the three-hole arrangement. Include shaft size, stationary-seat measurements, working length, service liquid and required quantity.

For measurement guidance, see How to Measure a Mechanical Seal.

Important Compatibility Notice

This is an aftermarket replacement product supplied by Hong Teng. CNP is used to identify the intended pump application, not to represent the product as an original CNP part. Fitment must be confirmed for the specific pump and seal configuration.

Frequently Asked Questions

Is this the stamped or the machined version?

This is the stamped-type version. The conventional machined / turned version is listed on a separate product page.

Can I order only by the three-hole appearance?

Do not confirm an order from hole count alone. Supply the complete pump identity, seal photos and the relevant installation dimensions for comparison.

Does this page confirm every size or CNP pump series?

No universal size or pump-series coverage is stated here. Confirm the available size and complete configuration for the selected stamped version with the quotation.
