Product Description
The APV 25/35 mm pump mechanical seal supplied by Hong Teng is an aftermarket replacement for selected APV W / World centrifugal pump applications using compatible 25 mm or 35 mm shaft-seal configurations.
These pumps can use different mechanical seal arrangements depending on the exact pump version. Therefore, the shaft diameter alone should not be used to confirm a replacement. The rotating seal, stationary face, working length, elastomer and complete pump model should be checked together before ordering.
Replacement configurations can be supplied with different seal-face and elastomer combinations according to the pumped liquid and operating conditions. Carbon / silicon carbide may be considered for selected sanitary and general liquid-transfer duties, while silicon carbide / silicon carbide can provide greater wear resistance where the application requires harder seal faces.
If the pump model or seal reference is unclear, send the complete APV pump nameplate together with clear photographs of the old rotating and stationary components. Shaft diameter, stationary-seat dimensions and working length can also be used for comparison. See our
mechanical seal measurement guide
for the dimensions to record.
APV, W, World and other manufacturer or pump-series references are used only for compatibility identification. This replacement product is independently manufactured and supplied by Hong Teng and is not represented as an original APV product.

Application
Applications
This APV 25/35 mm replacement mechanical seal is intended for selected APV W / World centrifugal pump applications where the shaft size, stationary-seat geometry, working length and seal construction match the existing assembly.
- Selected APV W / World centrifugal pump applications
- 25 mm mechanical seal configurations
- 35 mm mechanical seal configurations
- Food and beverage liquid-transfer equipment where compatible materials are selected
- Dairy and sanitary process-pump maintenance
- General industrial liquid-transfer applications using compatible seal dimensions
- Replacement matching by pump model, sample, photographs or dimensions
For sanitary applications, the final seal-face and elastomer materials should be selected according to the liquid, cleaning process and required material specification. You can also review our
food-grade mechanical seal selection guide
when evaluating seals for dairy and beverage pump service.
APV W / World and W+ pumps should not be assumed to use the same replacement seal solely because the shaft size is 25 mm or 35 mm. Confirm the complete pump designation and existing seal construction before ordering.
How to Confirm an APV 25/35 mm Replacement Seal
For original W+ shaft-seal construction and service-part reference information, see the
APV W+ shaft seal documentation from SPX FLOW
.Before ordering an APV replacement mechanical seal, compare the pump identity and removed seal instead of relying only on the nominal shaft diameter.
01. Pump Model
Send the complete APV pump model and a clear photograph of the pump nameplate.
02. Old Seal Photos
Photograph the rotating seal, stationary seat and complete removed assembly.
03. Dimensions
Confirm 25 mm or 35 mm shaft size, seat dimensions and working length.
04. Materials & Service
Send the pumped medium, temperature, cleaning conditions and existing face and elastomer materials.
