Description
When your Aquaclipse air pump starts failing, ozone delivery drops and contaminants like iron, sulfur, and bacteria start slipping through. The original crankshaft pump has more moving parts and draws more current than necessary, which means more wear, more power consumption, and more frequent pump replacement.
The WDAP runs on just 0.28 amps, half the electrical energy of the original S40-BA33F, while still delivering 8 psi through a twin bellow design that produces a consistent pattern of fine air bubbles. With fewer moving parts, it lasts 300% longer under continuous duty conditions, significantly extending the interval between replacements and reducing overall pump parts costs.
As a supplemental sanitizer for your Del Ozone system, consistent pump operation keeps ozone output steady and chlorine-resistant contaminants under control. It installs as a direct drop-in replacement with no modifications required.

Features
At 0.28 amps, the WDAP cuts energy draw in half compared to the original crankshaft pump, reducing operating costs without sacrificing ozone output.
The twin bellow design eliminates the mechanical complexity of the original S40-BA33F, making pump failure significantly less likely over the long term.
A 300% longer service life means fewer purchases, less downtime, and a lower total cost of ownership than the pump it replaces.
Reliable ozone delivery at 8 psi keeps your sanitation system performing consistently, preventing chlorine-resistant contaminants from reestablishing in your water supply.
Check valve compatibility ensures the ozone line stays protected after installation, guarding the pump against moisture backflow.
Frequently Asked Questions
-
It is strongly recommended. A failing or stuck check valve is one of the most common causes of moisture reaching pump internals, which accelerates wear and can cause premature pump failure. If your previous pump failed early, the check valve may have been a contributing factor. Replacing both at the same time ensures the new WDAP starts with a fully protected ozone line.
-
Yes. The WDAP is a continuous duty pump, meaning it is designed to run without cycling off. A residential ozone treatment system requires uninterrupted ozone delivery, and the WDAP is built to handle that demand. If the pump becomes unusually hot during operation, check for a kinked or blocked ozone line, as backpressure causes the motor to work harder than it should.
-
Not necessarily. The WDAP connects to the same ozone and air line tubing used with the original ZO-400, so existing tubing does not need to be replaced unless it shows visible deterioration such as cracking, yellowing, or stiffness. Ozone degrades certain tubing materials over time, so if your tubing is several years old, inspecting and replacing it during the pump swap is worthwhile.
-
Sticking to the recommended schedule of replacing the membrane every 18–36 months is the most reliable way to keep your system performing consistently.
