Kärcher BP 4 Deep Well Immersion Pressure Pump, 700 W, 4600 l/h, 43 m, 12 m, Stainless Steel

The KÄRCHER BP 4 Deep Well immersion pressure pump is designed for garden watering and domestic process water supply from deep wells or cisterns. Running on mains electricity, it draws water directly from submerged sources for a steady household or light agricultural supply. The unit is driven by a 700 W motor and delivers a maximum flow rate of 4,600 l/h. For vertical extraction, it provides a maximum delivery head of 43 m, making it suitable for moving water well above the source level.

Built for continuous submersion, the pump has a stainless steel housing that resists rust and corrosion. It weighs 7.1 kg and includes carrying handles to help lower and retrieve it from narrow shafts. A 15 m power cable provides enough reach to surface-level outlets in deeper installations. An integrated water filter protects the internal components from debris. Operation is handled via a simple on/off switch, giving manual control over the pump. The unit is rated for outdoor use, so it can be installed in external wells without additional weather protection.

• Maximum operating pressure of 4.3 bar – maintains steady water delivery across extended pipe runs.
• Maximum immersion depth of 12 m – allows placement deep below the surface in underground reserves.
• Maximum particle size of 0.9 mm – prevents fine sand and grit from damaging the internal impeller.
• Maximum water temperature of 35 °C – suitable for groundwater and sun-warmed cisterns.
• G1 connecting thread – ensures straightforward compatibility with common hoses and domestic plumbing fittings.
• 105 mm diameter – fits easily into narrow well shafts and tight underground pipes.
