SR0503N | 0.5HP (0.37kW) Sta-Rite, 3 Phase Pump

Product Overview

As an experienced hot tub and pool equipment supplier, I’m excited to introduce you to the SR0503N Sta-Rite pump. This 0.5HP (0.37kW) powerhouse is designed to deliver exceptional performance and durability for your aquatic systems.

Key Features

Precision-Engineered Construction

The Sta-Rite 5P2R series pumps, including the SR0503N, are meticulously crafted using reinforced fiberglass. This innovative material offers superior temperature and corrosion resistance, making it ideal for the demanding environment of hot tubs and pools.

Lightweight Yet Robust Design

Despite its lightweight nature, this pump is engineered for high-pressure operations. The thermoplastic construction provides exceptional strength, ensuring long-lasting performance even under challenging conditions.

Advanced Self-Priming Technology

Featuring a self-priming diffuser design, this pump eliminates the hassle of manual priming. It’s a feature I’ve found particularly beneficial for both new and experienced hot tub owners.

‘Hi-Rise’ Mounting Base

The unique ‘Hi-Rise’ mounting base enhances stability and makes installation a breeze, saving you time and effort during setup.

High-Performance Impeller

The high head impeller is precision-molded from glass-filled polycarbonate. Its smooth water passages contribute to outstanding performance and efficiency, ensuring optimal water circulation in your hot tub or pool.

Heavy-Duty Motor

Designed for continuous and quiet operation, the 50Hz motor is a true workhorse. It features a stainless steel shaft and permanently lubricated bearings, promoting cooler operation and extended lifespan, even in high ambient temperatures.

Advanced Seal Technology

The mechanical seal, constructed from precision-lapped carbon ceramic and stainless steel, provides maximum drip-proof and corrosion-free protection. This feature significantly enhances the pump’s longevity and reliability.

Easy Maintenance

A stainless steel pump clamp allows for quick access to all serviceable components, making maintenance straightforward and efficient.

Transparent Trap Lid

The ‘see-through’ trap lid is not only convenient for visual inspections but also robust enough to withstand 4 bar test pressure and high vacuum conditions.

Large Capacity Basket

The pump comes with a big 5″ lock-in basket, reducing the frequency of cleaning and maintenance.
