Pool specialist opinion
- + Transparent lid makes it easy to spot a clogged basket.
- + Large prefilter captures debris before it reaches the pump.
- + Thermal motor protection.
- − Fixed speed: filtration times must be adjusted using an external controller.
- − 50 mm connections require suitable adapters for pool hoses.
Our recommendation: FreeFlo 12 suits customers who want straightforward filtration without adjustable-speed controls. Before replacing an old pump, compare its operating flow, pipe connections and installation space. A higher flow is not automatically better: it must match the filter.

Everyday filtration with easy basket inspection
The large prefilter collects leaves and other debris carried into the filtration circuit. The transparent lid lets you check the basket without opening the pump. Clean it regularly so that accumulated debris does not restrict water flow.
Included in the box
Pump with motor, strainer basket, transparent lid with seal, two swivel unions for 50 mm pipework and operating instructions.
For freshwater pool water. Not suitable for saltwater pools.

Dimensions and installation space
Pump dimensions without connection unions (L × W × H): 562 × 230 × 242 mm. With the suction union fitted, the overall length is approximately 607 mm. The 45 mm difference is the projection of the suction union. The drawing height of 242 mm excludes the upper discharge union.
The suction centreline is 153 mm above the base and the transverse mounting-hole spacing is 102 mm. Allow clearance above the strainer for basket removal and around the motor for ventilation.

Choosing the right pump
The actual flow depends on pipe length, fittings, height differences and filter resistance. Match the pump to your filter’s permitted flow and compare performance curves at the expected operating head. Contact us with your pool volume, filter model and pipework details if you need help choosing.
Installation and maintenance
Use a stable base and allow access to the prefilter lid. Protect the installation from flooding and frost, and keep the motor ventilated. Before opening the lid, disconnect the power and release system pressure. Never run the pump dry. Shut-off valves on both sides make servicing easier.
For 50 mm pipework you may need PVC flexible hose, shut-off valves and PVC adhesive. For 32 or 38 mm hoses, check the correct adapters before ordering.
