Waterway 48f 4HP Hi-Flo Wet End (2×2) HA440 Replacement

Product Overview

As an experienced hot tub parts supplier, I’m excited to offer you the Waterway 48f 4HP Hi-Flo Wet End. This high-quality replacement part is designed to breathe new life into your hot tub pump, ensuring optimal performance and longevity for your spa system.

Key Features

Versatile Compatibility

The Waterway 48f 4HP Hi-Flo Wet End is a perfect replacement for the older style Hydroair HA440 wet end. Through rigorous testing, I’ve confirmed that this unit fits flawlessly with both old and new HA440 models, regardless of whether you have a single-speed or 2-speed system.

Complete Assembly

This isn’t just a partial replacement – you’re getting a complete wet end assembly. The package includes:

• Housing
• Face plate
• Face plate O-ring
• 4.0HP impeller
• Ceramic seal kit

Convenient Design

The wet end comes with two built-in bleed screws, making maintenance and air removal a breeze.

Technical Specifications

Specification	Detail
Manufacturer	Waterway
Connections	2 x 2 inch Waterway unions
Attachment Method	4 small bolts to pump body
Impeller Attachment	Screws onto protruding shaft
Built-in Features	2 bleed screws

Connection Details

Both the suction and pressure ports feature a flat, smooth connection. This design requires the O-ring to be attached to the union sleeve for a secure, leak-free fit. The wet end itself houses the female receptacle part of this attachment system.

Versatility in Power

While this wet end is labeled as 4HP, it’s important to note its versatility. I often fit this unit to 2HP Waterway pumps, and when sold as a complete pump, it’s typically marketed as a 2HP system. This flexibility allows for a wide range of applications and replacements.

Easy Installation

Installing this wet end is straightforward. The unit attaches to the pump body using four small bolts, ensuring a secure fit. The impeller easily screws onto the shaft protruding from the center of the pump body, allowing for quick replacement if needed.

Why Choose This Wet End?
