The GJSm800 combo is a stainless steel self-priming jet pump pre-assembled with an automatic flow controller, wiring and plug. Stainless steel keeps the water clean and resists rust; self-priming means it can draw water from a tank or shallow well below the pump.
- Power: 0.8kW, 220V
- Maximum head: 42m
- Stainless steel pump body
- Self-priming

What is a booster combo? The pump comes pre-assembled with an automatic flow controller, wiring and a 3-point moulded plug – connect the pipes, plug it in and it runs by itself: the pump starts when you open a tap and stops when the flow stops.
Choosing the right booster pump: count the taps and showers that will run at the same time and how high the water must go (a double-storey house needs more head than a single storey). Each 10m of head is about 1 bar of pressure. Pick a pump whose head at your flow is comfortably above what you need. Not sure? Send us your setup (tank position, number of bathrooms, storeys) and we will recommend a pump.
