Flygt 2125.181 High Head Dewatering Pump – 13 HP with Discharge Elbow
The Flygt 2125.181 is a compact, high head, 2-stage submersible dewatering pump from the Flygt 2000 series, built in lightweight aluminium for portable site use. This unit is supplied in Imported, Refurbished & Tested condition, and comes fitted with a bolted discharge elbow and a 3 inch male threaded outlet, so it is ready to connect to a hose coupling or pipeline as soon as it arrives on site.
With a 13 HP (9.7 kW) motor, the pump is rated for up to 75 m head and up to 72,000 LPH. Its 2-stage hydraulic design lets a relatively small pump push water to heights and distances that usually need a much larger unit, which makes it a favourite for deep excavations, shafts and long discharge lines.
Why the Discharge Elbow Matters
On a bare pump, the outlet faces sideways and the buyer must source a matching bend or flange adapter before use. This unit already has the elbow and threaded outlet assembled, which means:
- The discharge turns upward, so the hose rises straight out of the pit without kinking
- A standard 3 inch hose coupling or threaded pipe fitting can be screwed on directly
- Less time and cost spent sourcing adapters before the pump can be put to work

Voltage & Power Note
This pump runs on a 3 phase, 380–440 V supply. Flygt's published data for the 2125.181 is for 60 Hz operation. On a 50 Hz supply, such as standard Indian 415 V, 50 Hz power, the pump runs about 17% slower; by the pump affinity laws, head drops to about 69% (approx. 52 m maximum) and flow to about 83% (approx. 60,000 LPH maximum).
For full rated performance in India, the pump can be run through a VFD set to 60 Hz output. Use a DOL starter, star-delta starter or VFD with overload, phase-failure and earth protection, and keep starts within Flygt's limit of 15 per hour.
Safety Note
- This refurbished unit is not offered as explosion-proof and must not be used in hazardous areas
- Pump water only, including water with sand, silt and abrasives; not for oil, fuel, solvents or flammable liquids
- Do not install deeper than 20 m below the liquid surface; maximum liquid temperature is 40 °C
- Lift and lower the pump only by its lifting bail using a chain or rope, never by the power cable or hose
- Support the discharge hose so its weight does not hang on the threaded outlet
- Always connect the earth conductor before use
Maintenance Tips
- Check the oil in the seal chamber at regular intervals; water in the oil indicates seal wear
- Inspect the impellers and wear parts if head or flow drops
- Keep the strainer clear of mud and debris
- Check the elbow bolts and gasket for leaks after installation
- Check motor insulation resistance before installation
- After pumping abrasive water, flush the pump with clean water where possible
Frequently Asked Questions
What is the Flygt 2125.181 used for?
It is a high head submersible dewatering pump for construction sites, deep excavations, shafts, mines, tunnels and flooded areas, where water must be lifted to a large height or pushed through long pipelines.
How much head and flow does the Flygt 2125.181 give?
This unit is rated for up to 75 m head and up to 72,000 LPH. Maximum head and maximum flow occur at different points on the pump curve, not at the same time.
What is the outlet size?
The pump is fitted with a bolted discharge elbow ending in a 3 inch male threaded outlet, ready for a hose coupling or threaded pipe fitting.
Is the Flygt 2125.181 a 2-stage pump?
Yes. The 2125.181 is the 3 inch high head, 2-stage version in the Flygt 2125 range, which is how it reaches high heads from a 13 HP motor.
Will it work on Indian 415 V, 50 Hz power?
Yes, on a 3 phase supply. Flygt's data for this model is for 60 Hz, so on 50 Hz it runs about 17% slower with reduced head and flow. A VFD set to 60 Hz output restores full performance.
How deep can it be submerged?
The maximum depth of immersion is 20 m.
How heavy is it?
The pump weighs about 78 kg and has a steel lifting bail for handling with a chain hoist or crane.
Do you export Flygt pumps?
Yes. Standard Machinery supplies across India and exports to Africa, the Middle East and Southeast Asia. Contact us for export packing and shipping details.
