ApplicationsThe main application of the GP pump is circulation ofswimming pool water in small and medium sized swim-ming pools.

The pump incorporates a removable filter basket to filterout leaves, twigs and other large solids. The GP pumpmust therefore be installed between the skimmer andthe pool filter.

Features and benefits• Complete range of pumps.

• Built-in motor protection.

• Stainless steel shaft.

• Low sound level.

• Self-priming down to 2 m.

• CE-marked.

• Corrosion resistant materials.

• No need for special service tools.

• Quick and easy to repair.

GPThe GP swimming pool pump is a horizontal close-coupled, centrifugal pump. Made of high-quality mate-rials, the GP pumps guarantee the user a long pump life.

The GP pump is equipped with a removable basketwhich protects the pump against possibly impurities inthe pumped liquid (water).

The compact construction makes the installation quickand easy. The installation requires very little space.

The single-phase pumps are equipped with a thermalprotection. The three-phase pumps must be connectedto an external motor protection.
