1. Find Your Pump Type and Material Code
The pump type is printed on the nameplate (for example "gamma/ X 1602"). The material code (PVT, PVF, PPB, SST…) is part of the type designation — it tells you which wetted materials your pump head uses.

3. Spare Diaphragms (Without Kit)
If the valves and seals are still serviceable, order the diaphragm alone:
| Pump Type | Order No. | Note |
|---|---|---|
| Type 1602 (gamma/ X) | 1000246 | Spare diaphragm, all materials |
| Type 1604 / 2504 (gamma/ X) | 1034612 | Spare diaphragm, all materials |
| Type 0708 / 1009 (gamma/ X) | 1000248 | Spare diaphragm, all materials |
| Type 0414 / 0715 (gamma/ X) | 1000249 | Spare diaphragm, all materials |
| Type 0220 / 0424 (gamma/ X) | 1045456 | Spare diaphragm, all materials |
| Type 1608 / 2508 (gamma/ XL) | 1030353 | Spare diaphragm |
4. Liquid End Material Codes Explained
The two-letter suffix on the pump type names the wetted materials. Match it exactly — a PVT head and a PPB head use different seals and valve balls.
| Code | Head | Valve Balls | Diaphragm |
|---|---|---|---|
| PVT | PVDF | Ceramic | PTFE |
| PVF | PVDF | PTFE | PTFE |
| PPT | Polypropylene | Ceramic | PTFE |
| PPB | Polypropylene | Glass | PTFE |
| NPT | Noryl | Ceramic | PTFE |
| NPB | Noryl | Glass | PTFE |
| SST | Stainless steel | Ceramic | PTFE |
5. Replacement Tips
- ✓ Confirm the type and material code before ordering — gamma/ X 1602 PVT and 1602 PPB take different kits.
- ✓ The spare parts kit includes the diaphragm, valve balls, valve seats and seals — everything the liquid end needs.
- ✓ Replace the diaphragm every 12–24 months or when output accuracy drifts beyond ±2%.
- ✓ For older pumps with a worn head, order the full spare parts kit plus a check of the injection valve.
Frequently Asked Questions
Are these ProMinent OEM part numbers?
Yes — the order numbers above are published by ProMinent on their official spare parts pages. We supply compatible equivalents cross-referenced to these numbers, and can source OEM on request.
How do I read my pump's type code?
The nameplate shows the full type, e.g. "gamma/ X 1602 PVT". The digits (1602) are the pump type; the suffix (PVT) is the material code.
What's the difference between a spare parts kit and a spare diaphragm?
The kit contains the diaphragm plus valve balls, seats and seals — a full liquid-end service. The diaphragm alone suits a quick replacement when the valves are still good.
