More about this product
Product overview
The Pedrollo 3SR 5/24 is a 1.1 kW (1.5 HP) 3″ submersible borehole pump with motor for clean water on a 400 V three-phase supply, covering 15 to 120 l/min with a working head of 70 m down to 24 m. Its slim 76 mm body fits wells and boreholes 3″ wide or more.
The 3SR combines efficient hydraulics with a high-efficiency, rewindable 2-pole motor in an oil bath of non-toxic, food-safe oil. It suits household water supply, irrigation and small community systems, and handles water with up to 150 g/m³ of sand. Its AISI 316L bearings have a chromium oxide coating for durability in sandy water, and the delivery port, check valve, motor bracket, shaft, filter and cable sheath are AISI 304 stainless steel.

Frequently Asked Questions
Quick answers to common questions about the Pedrollo 3SR 5/24 Three Phase 2207800. For technical specifications, see the product details above; for sizing or installation advice, contact our team. If you have any other questions, we're happy to help.
What is a submersible pump?
A submersible pump is designed to operate fully submerged in the liquid it is moving. The motor is sealed inside the pump body and cooled by the surrounding water. Submersibles are used for drainage, sewage, septic tanks, deep wells and boreholes, and for raising water from sumps, cellars and floodwater. Many stocked at Anglian Pumping handle solids in suspension.
Can submersible pumps handle solids and sewage?
Yes – some submersibles are designed for clean water only, others handle solids up to 50 mm or full raw sewage. Anglian Pumping stocks ABS, BBC, Flygt and T-T Submersibles ranges that include vortex, single channel and grinder impellers for different solids handling requirements. Always match the pump to the maximum solid size and the type of effluent it will see.
When should I use a submersible pump instead of a surface pump?
Use a submersible when the water level is more than around 8 metres below the pump installation point – surface pumps cannot self-prime beyond that depth. Submersibles are also better when the liquid contains solids, when noise must be minimised, or when the pump needs to operate in confined spaces such as sumps and chambers where a surface pump would not fit.
