Val-Pak
SKU: V38-130
Val-Pak V38-130 Ultra-Flow Pump Volute (2") – Black
The Val-Pak V38-130 is a replacement 2" volute (wet-end housing) designed for select Pentair / American Products Ultra-Flow pool pumps. The volute is the pump housing that directs water from the impeller to the discharge outlet. Replacing a cracked or warped volute can restore proper flow, stop external leaks, and help bring the pump wet end back to original performance.
Key Features
- Replacement volute housing for Ultra-Flow pump wet ends
- 2" discharge / volute size (confirm your existing wet end is the 2" version)
- Designed to restore correct internal water path and pump efficiency
- Durable, heavy-duty construction for long service life
- Color: Black
Compatibility
- Fits select Pentair / American Products Ultra-Flow pumps that use the 2" volute
- Commonly referenced as replacement for manufacturer part numbers 39007000 and 357140
- Best practice: match your old housing by part number V38-130 and confirm the outlet size and bolt pattern before ordering
What’s Included
- (1) Volute housing (2"), black
Common Reasons to Replace
- Cracks in the volute from freeze damage or overtightened fasteners
- Seeping or dripping from the wet end after confirming seals and gaskets
- Warped sealing surfaces causing repeated gasket leaks
- Physical damage to the discharge/outlet area
Installation Notes
- Turn off power at the breaker and close valves before opening the pump.
- Replace the housing gasket when swapping the volute to prevent leaks.
- Inspect the seal plate, diffuser, and shaft seal while the wet end is apart; replacing worn seals during service helps avoid rework.
- Tighten fasteners evenly in a crisscross pattern—do not overtighten.

Maintenance Tips
- Keep baskets and the filter clean—restricted flow increases heat and stress on wet-end components.
- If you ever see water under the pump, check the shaft seal area first; catching small leaks early helps prevent housing damage.
- For freeze-prone areas, fully drain the pump and wet end during winterizing to reduce cracking risk.
- After wet-end service, monitor for drips for the first day of operation and recheck fastener tightness (snug only, not overtight).
