Product Information

Property Details
Brand QB
Specifications Technical Details

This pump operates on a standard 220–240 V, 50 Hz electrical supply and is rated at approximately 1850 W, providing around 2.5 horsepower of pumping power. The high-capacity motor delivers strong water flow suitable for vigorous spa jet operation and rapid circulation in swim spas.

The pump features standard union fittings compatible with most Australian spa plumbing layouts. Its wet end is constructed from durable, moulded materials designed to withstand high pressures and prolonged operation. The internal shaft is stainless steel, providing excellent resistance to corrosion from chlorinated, brominated, or lightly salted water.

The wet-end housing can be rotated, allowing either horizontal or vertical discharge to accommodate various spa cabinet layouts. Properly installed, the pump delivers consistent flow with moderate noise levels for residential spa environments.

High-power jet capability: Ideal for multi-jet spas or swim-spas, offering firm, pressurised hydrotherapy.

Water circulation: Ensures effective water turnover, even distribution of heat, and filtration support.

Replacement or upgrade: Compatible with existing spa plumbing and AMP-style connections, making it suitable for retrofit or new installations.

Documentation Installation & Use Considerations

Installation must comply with Australian electrical standards. Connect the pump to a 220–240 V circuit with RCD protection and, if applicable, ensure the spa controller is compatible with the AMP plug connection.

Use the supplied union fittings for plumbing connections, hand-tightening to protect O-rings and prevent leaks. Avoid using sealants or tapes on the unions. Ensure suction and discharge lines are free from sharp bends or restrictions to maintain optimal flow.

Provide adequate ventilation around the pump motor, especially in enclosed spa cabinets, to prevent overheating. Before the operation, fill the spa to the correct water level and prime the pump to avoid running dry. Maintain balanced water chemistry to protect the wet-end, shaft, and seals, prolonging pump life.
