Product Information

Brand Spanet
Specifications Technical Details

This pump operates on a standard 220–240 V, 50 Hz electrical supply and draws approximately 1850 W, delivering about 2.5 horsepower. As a single‑speed unit, it provides continuous, high-volume water flow with substantial head pressure — capable of powering spa jets, swim jets, and supporting peak circulation needs.

The wet end and impeller are manufactured from corrosion-resistant materials suitable for treated water environments (chlorinated, brominated, or salt systems). The 50 mm union connections for inlet and outlet ensure compatibility with common pool and spa plumbing standards, facilitating straightforward installation or retrofit.

When installed with correctly sized and unobstructed suction and discharge plumbing, the pump delivers stable hydraulic performance. Vibration and noise are manageable with correct mounting and adequate support for plumbing lines, even under continuous high-load operation.
Functionality High-flow water circulation: Provides strong, continuous flow for spa jets, swim‑spa jets, and pool‑spa circulation.

Jet and hydrotherapy support: Supplies the necessary pressure and volume for powerful jet streams and hydrotherapy systems.

Filtration and heating support under heavy load: Maintains circulation even under high demand for heating or water turnover.

Retrofit or upgrade compatibility: 50 mm union fittings make it suitable for many standard pool/spa plumbing systems.
Key Features 2.5 hp motor (1850 W) — delivers high hydraulic power suitable for demanding spa or pool‑spa systems.

Single‑speed design — provides constant, stable flow and pressure for jets and heavy‑duty circulation needs.

Corrosion‑resistant wet end and impeller, built to endure treated water environments over time.

50 mm union fittings, enabling easy installation or replacement in standard plumbing layouts.

Robust construction and high head capacity, ideal for jet systems, swim spas, or large spa installations.

Compact and durable build, suitable for residential equipment spaces while offering strong performance.

Standard electrical compatibility, operating on a standard 220–240 V supply without the need for specialised wiring.
Documentation Installation should comply with local Australian electrical and plumbing regulations. Connect the pump to a 220–240 V circuit with RCD/earth‑leakage protection. Use 50 mm unions for plumbing connections, ensuring O‑rings are correctly seated, and unions are tightened by hand — avoid using tapes or sealants that may interfere with sealing surfaces.

Ensure suction and discharge plumbing lines are correctly sized, smooth, and free from bends or restrictions to maintain optimal flow and prevent cavitation or pressure loss. Prime the pump before operation to avoid dry‑running, which can damage seals or the impeller.

Because this is a high‑power pump, ensure the mounting base is stable, plumbing is adequately supported, and vibration dampening is considered. Regular maintenance is recommended, including inspection of seals, unions, and plumbing for leaks, and maintaining balanced water chemistry, especially in salt or chemical-treated systems.


Why It's a Good Choice

The SpaNET 1850 W (2.5 hp) Single‑Speed Booster Pump with 50 mm Unions by Spa‑Craft is an excellent choice for pool and spa owners who need strong, reliable water flow and high pressure — especially where jets, swim‑spa features, or heavy-duty circulation are used.

With robust power output, corrosion-resistant components, and compatibility with standard plumbing, this pump is well-suited for demanding spa setups and larger pool‑spa installations, offering dependable performance and long-term value.
