LX / Davey QB / SpaNet Jetmaster / LP WP Whirlpool Wet Ends - Complete

LX / Davey QB / SpaNET Jetmaster / LP WP Whirlpool Complete Wet End

Is your spa pump leaking? This is usually the best fit.

Complete replacement wet end assembly to suit selected Davey QB, SpaNET Jetmaster, and LX Whirlpool LP / WP series spa pumps. Supplied as a complete wet end including pump body, impeller, mechanical seal, O-ring, and screws.

We keep these physically in stock for fast shipping or local pick-up, unlike most drop-shipping websites.

This wet end is commonly used on a wide range of LX-built spa pumps sold under Davey, SpaNET, and other spa brands. It is supplied with the fine thread union style. If you have an older coarse-threaded wet end, you will generally need the coarse-to-fine thread adaptors.

The latest version now comes with a PPO chemical-resistant impeller. Early versions used black impellers that wore and even absorbed water!

Important Fitment Notes

• If your existing wet end is coarse thread, you will need coarse-to-fine thread adaptors.
• On some older Davey QB or LX LP / WP pumps, the inside lip of the wet end may need minor reaming when adapting from coarse to fine threaded nuts.
• Some pre-2007 pumps may not suit due to untracked historical variations.
• Some older versions with an air bleed nipple may no longer be directly reusable in the same way, and your current notes state the bleed may need to be plugged or removed if necessary.
• If you are not willing to take some fitment risk on older or unusual pumps, replacing the complete pump may be the better option.

Before Ordering

Please compare your existing wet end carefully before ordering. The most important things to check are horsepower, thread type, union size, mounting pattern, and overall wet end shape. Many LX-based pumps look similar but are not always identical.

If you are unsure, send us clear photos of your existing wet end, pump label, and union thread, along with your pump model number.
