GPPerformance curves
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.
