4HP Two-Speed Spa Pump with Bracketless LX Motor for 220-240V Spas (OEM# 6500-367 56WUA400-II)

This pump, designated as Model #56WUA400-II(NF), is bracketless and baseless, distinguished from its counterpart Model #56WUA400-II with a base. Despite the absence of a base, their performance remains identical. Catering to OEM requirements, it serves as a suitable replacement for Model #6500-367. Prior to installation, considerations include voltage compatibility, amperage draw, and the dimensions of inlets and outlets.

The pump's discharge is located at the 12:00 position and is rotatable by 90 degrees, allowing for adjustment to either the 3:00 or 9:00 positions. Two sets of 2-inch unions are provided, although it's recommended to use ours for optimal sealing, as factory alternatives may vary slightly.

With a maximum operational pressure of 0.3Mpa and a flow rate of 202GPM at 4HP, this is a 2-speed pump featuring a 56-frame design. It operates on 12A (high speed) and 4.4A (low speed) currents, and requires a 220-240V / 60Hz power input. It has earned UL and ETL certifications for safety and reliability.

The motor boasts superior copper winding for efficient cooling, backed by a Texas Instruments thermal protector. It comes with two sets of 2-inch unions, each rigorously tested for waterproofing, high-pressure resistance, endurance under hot water, and withstands 80,000 charge-discharge cycles, along with a 500V AC impulse test.

Sealed with Viton, Silicon Carbide, or Graphite, the pump seals exhibit resistance to extreme temperatures, corrosion, and maintain high hardness for dependable performance. Enhanced by an anti-creep bearing lubricated with high-temperature grease, the pump ensures quiet operation.

In summary, Model #56WUA400-II(NF) is a robust, efficient, and reliable pump option, equipped with top-quality components that guarantee optimal performance and longevity in various applications.
