Know before you buy
Yes, this unit is specifically engineered for 48-frame motors. As long as your current motor matches this frame size, it will bolt on directly.
It arrives factory-assembled, meaning the housing, volute, impeller, and pump seal are already installed. You can mount it to your motor and connect your plumbing immediately.
You can verify this by measuring the outside diameter of the intake threads. For a standard 2-inch suction, the measurement should be approximately 2 7/8 inches.
This wet end is designed as a direct replacement for Waterway Executive pumps. While some components may occasionally cross over, we recommend sticking to the Waterway Executive line to ensure proper fitment and performance.
Before installation, inspect your motor shaft for any signs of corrosion or damage, as a clean shaft is essential for a proper seal. It is also a good time to check your plumbing unions to ensure they are not cracked or worn, which could cause leaks.
