🔋 Waterway 56-Frame Jet Pump – 2.0 HP Dual Speed – 2.5″ x 2″ Connections

Versatile two-speed power with larger suction for high-flow spa systems

💧 Product Overview

The Waterway 2.0 HP 56-Frame Dual Speed Pump with 2.5″ x 2″ connections is a versatile jet pump designed for both heating circulation and boost jet operation in hot tubs requiring larger plumbing diameter. Featuring a two-speed motor with 0.53 HP at low speed and 2.14 HP at high speed, paired with a 4 HP-rated wet-end impeller, this pump delivers reliable performance with improved water flow.

Operating at 230V/50Hz, the pump provides efficient dual-speed operation. Low speed runs at 1,450 RPM drawing just 1.8A for quiet heating circulation, whilst high speed runs at 2,850 RPM drawing 9A for powerful jet performance. The split-capacitor design (16 µF for low speed, 30 µF for high speed) ensures reliable starting and operation on both speeds. The larger 2.5-inch suction port enables maximum water intake for improved flow compared to standard 2-inch models.

The pump features 2.5-inch x 2-inch Waterway union connections (sold separately), providing excellent compatibility with many hot tub brands including Hot Tubs Direct, Knightswood Leisure, Touch Spas, Catalina, Hydropool, Hotspring, Hotspot, and Southwest Spas. This pump can replace pumps from Waterway, Vico, Sta-Rite, GE, Emerson, A.O Smith, ITT, and Aqua-Flo. No electrical cable is supplied – your existing wiring must be reused.

⚠️ IMPORTANT ELECTRICAL SAFETY:

All electrical work must be carried out by a qualified electrician in accordance with UK wiring regulations (BS 7671). Hot tubs require RCD protection (30mA). Ensure proper earthing and bonding of all electrical components. Two-speed pumps require appropriate wiring for both speed windings – consult a qualified electrician. The electrical cable is not supplied – your existing wiring from the previous pump must be reused and inspected before connection.

Check motor operation	Weekly	Listen for unusual sounds
Verify jet performance	Monthly	Ensure strong water flow on high
Inspect wiring	Annually	Check all connections
Clean pump strainer	As needed	Remove debris

Warning Signs – Consider Replacement If:

• One speed stops working (possible winding or capacitor failure)
• Motor hums but doesn’t start
• Unusual noise or vibration
• Motor overheating
• Significantly reduced jet/flow power
• Pump trips the circuit breaker
• Visible seal leakage

Capacitor Information:

The 2-Speed uses a split-capacitor design:

• 16 µF capacitor (low speed)
• 30 µF capacitor (high speed)

Both capacitors must be functioning correctly for reliable two-speed operation.

❓ Frequently Asked Questions

Q: What is the power rating of this pump? A: The pump has a 4 HP-rated wet-end impeller. The motor produces 0.53 HP at low speed and 2.14 HP at high speed, drawing 1.8A (low) and 9.0A (high) at 230V/50Hz.

Q: What is the difference between this pump and the 2″ x 2″ version (PW-W5620)? A: This pump (PW-W5623) has a larger 2.5″ suction port for improved water flow, whilst the 2″ x 2″ version (PW-W5620) uses standard 2″ connections on both ports. The motor, power, and electrical specifications are identical. Choose based on your spa’s existing plumbing size.

Q: What are the two speeds used for? A: Low speed (1,450 RPM) is used for heating circulation – running continuously to maintain water temperature. High speed (2,850 RPM) delivers powerful jet performance for hydrotherapy and boost operation.

Q: How much power does each speed use? A: Low speed draws just 1.8A for efficient 24/7 operation, whilst high speed draws 9.0A for maximum jet power.

Q: What size are the plumbing connections? A: The pump uses a 2.5-inch suction and 2-inch discharge with standard Waterway unions, which are sold separately.

Q: Does this pump come with unions? A: No, the Waterway unions are sold separately to allow flexibility for your specific installation.

Q: Does this pump come with an electrical cable? A: No, the electrical cable is not supplied. You must reuse the existing wiring from your previous pump.

Q: What capacitors does this pump use? A: The 2-Speed uses a split-capacitor design with 16 µF for low speed and 30 µF for high speed.

Q: How does this compare to the single-speed version? A: The 2-speed version offers the advantage of energy-efficient heating circulation on low speed (1.8A), switching to full jet power only when needed. Single-speed pumps run at full power continuously.

Q: What hot tub brands is this pump compatible with? A: The pump is commonly used with Hot Tubs Direct, Knightswood Leisure, Touch Spas, Catalina, Hydropool, Hotspring, Hotspot, Southwest Spas, and many more.

Q: Can this pump replace other brands? A: Yes, this pump can replace pumps from Waterway, Vico, Sta-Rite, GE, Emerson, A.O Smith, ITT, and Aqua-Flo.
