SWQ H 1500 230 V high-pressure submersible pump with float switch
The SWQ H 1500 is a 1.5 kW stainless steel submersible pump designed to deliver technically clean raw water and slightly contaminated water to high elevations. The SWQ H series is designed for applications requiring high pressure – a delivery head of 38 m allows it to supply household systems from ring wells, irrigate large areas of crops and serve long delivery lines where standard SWQ series models lose pressure. The pump does not treat water – if water from a private source is to be used for drinking, it must be appropriately treated and its quality monitored.
Who it’s for
-
Homeowners with a ring well – a delivery head of 38 m ensures reliable water supply to home plumbing systems, even when the water table is deeper, without the need to install a deep-well pump.
-
Farms – the high head is ideal for supplying extensive irrigation systems and sprinklers, where reach matters as much as flow.
-
Installation companies – the cooling jacket enables safe drainage of deep excavations to a very low level without the risk of the motor overheating.
-
Maintenance departments – the automatic float switch and thermal protection allow long-term unattended operation when supplying process water outlets.
Applications
The SWQ H 1500 is designed for pumping technically clean raw water and slightly contaminated water – from ring wells, lakes, rivers and retention tanks – wherever the medium needs to overcome significant elevation differences or travel long pipeline routes. The impeller clearance is 5 mm, allowing small organic matter in suspension but ruling out operation with sand and other mineral contaminants – abrasive particles damage the SiC/Graphite/NBR seal and steel impeller.
The cooling jacket allows operation without fully submerging the motor – the unit is cooled by the medium flowing through the space between the double casing. The built-in float switch automatically stops the pump when the water level drops, protecting the system from running dry. Thermal protection in the winding provides an independent second line of protection during pumping cycles lasting many hours.
SWQ H 1500 pump features
- Suitable for pumping water with sand and sludge: NO – designed for technically clean and slightly contaminated water; a 5 mm impeller clearance does not mean it can handle abrasive particles
- Cooling jacket: YES – can operate without the motor being fully submerged
- Discharge outlet: 1½" threaded, vertical direction
- Thermal protection: YES (built into the motor winding)
- Float switch: YES – built-in, protects against dry running
- Operating mode: continuous

Frequently asked questions (FAQ) – SWQ H 1500 submersible pump
How does the SWQ H 1500 differ from the standard SWQ 1100?
The SWQ 1100 is a pump for quickly draining large volumes of water – 235 l/min at a head of 14 m. The SWQ H 1500 works the other way around: lower flow rate (200 l/min), but a head of up to 38 m. It’s the right choice wherever water has to be lifted to a great height or pumped over a long distance – wells, irrigation, and supplying a household system. For typical basement drainage, the SWQ 1100 is a better fit.
Can the SWQ H 1500 replace a submersible well pump in a ring well?
For a ring well – yes, as long as the water level is not too deep. The 38 m head allows it to supply a household system from a well several meters deep, with allowance for pressure losses in the pipework. The pump operates submerged in the well, and its cooling jacket allows it to run even when the water level is low. For deep drilled wells, a dedicated submersible well pump is a more suitable option.
The water level in the well has dropped – will the pump burn out?
The built-in float switch automatically turns off the pump when the water level drops to the minimum. The thermal protection in the winding provides a second, independent safeguard. Both mechanisms work in parallel, so a brief drop in the water level should not damage the device – the pump will stop and restart once the level rises again.
What can destroy the pump the fastest?
Running dry with a blocked float switch – without the pumped water to cool it, the motor overheats rapidly. Another hazard is heavily contaminated water – sand and mineral particles abrade the mechanical seal and stainless steel impeller. A third factor is pumped water above 35°C, which shortens the service life of the seals.
Where can I buy the SWQ H 1500 pump?
The pump is available from Dambat’s sales partners, specialist plumbing wholesalers, and authorized online distributors. Dambat does not sell directly to customers.
Where can I get it serviced after the warranty expires?
Warranty and post-warranty service is provided by Dambat, Adamów 50, Grodzisk Mazowiecki. IBO – 24-month (2-year) manufacturer’s warranty.
