Model: WILDEN P1 to P8, PS, PX, T-series, P100 to P1500, P220 to P1530, Brahma and High Pressure pumps
How to choose a genuine WILDEN wet end kit: kit families by pump type and size, and the elastomer code in your pump’s build code that names the kit. 498 kits.
| Inlet / Outlet Diameter | 1/2" to 3" pumps |
|---|---|
| Material | Elastomer sets in Buna-N, Neoprene, FKM, EPDM, Hytrel, Santoprene, polyurethane, Bunalast and PTFE with rubber back-ups |
A wet end kit groups the wetted wear parts of a WILDEN pump under one part number, so a rebuild can be ordered in one line instead of piece by piece. Wilden lists 498 wet end kits. Choosing the right one takes two pieces of information: the kit family for your pump, and the elastomer code from its build code.
The middle group of a kit number tells you which pump design it is for:
| Kit number | Family | Listed for |
|---|---|---|
| xx-9804 | Original, clamped, metal | P1, P2, P4, P8 and their PS, PX, PV and T versions; at 3″ PS15, PX15, T15 |
| xx-9805 | Original, clamped, plastic | P1, P2, P4, P8 and their PS, PX and T versions |
| xx-9806 | Stallion, clamped, metal | 1-1/2″, 2″ and 3″ clamped pumps |
| xx-9814 | Advanced, bolted, metal | P400, P800, P1500 families; at 1″ the FIT P200 to P230 family |
| xx-9815 | Advanced, bolted, plastic | P100, P200, P400, P800, P1500 families |
| xx-9824 | Advanced FIT, bolted | P420/P430, P820/P830, P1520/P1530 families |
| xx-9834 | Brahma | PS810, PS1510 and related models |
| xx-9844 | High Pressure | H220, H430, H800 |
The first two digits are the size code as usual: 01 for 1/2 inch up to 15 for 3 inch.
The third group of your pump’s build code, for example BNS in P8/AAAPP/BNS/BN/BN, is the same code Wilden uses to label wet end kits. Common codes:
| Code | Material | Code | Material |
|---|---|---|---|
| BNS, BNU, BLL | Buna-N | TNU | PTFE with Neoprene back-up |
| NES, NEU | Neoprene | TWS | PTFE with Santoprene back-up |
| VTS, VTU | FKM | TSS, TSU | PTFE with Hytrel back-up |
| EPS, EPU | EPDM | TEU, LEL | PTFE with EPDM back-up |
| FSS, ZSS, SSL | Hytrel | ZGS | Bunalast |
| WFS, FWS, ZWS, WWL | Santoprene | PUS, ZPS | Polyurethane |
A clamped aluminum P8 with build code P8/AAAPP/BNS/BN/BN is an Original clamped metal pump (9804) at 2 inch (08) with the BNS elastomer code. That points to 08-9804-52, Buna-N (BNS). For a bolted P820 with code ZWS, the FIT family at 2 inch gives 08-9824-58-209, Santoprene (ZWS).
