4" SKT 150 – peripheral 400 V submersible pump
The 4" SKT series comprises monoblock peripheral submersible pumps with a 4" diameter, powered by three-phase 400 V voltage and equipped with a brass impeller and brass connectors. They are designed for installations requiring higher power with low current consumption – available in 1.1 and 1.5 kW versions with a 15 m cable terminated with a plug.
Who it is for
-
Farms and industrial facilities – 400 V power supply and greater head (up to 120 m) allow the pumps to handle deeper wells and higher water demand in facilities equipped with a three-phase electrical installation.
-
Owners of multifamily homes and service facilities – the three-phase motor draws significantly less current than single-phase equivalents at the same power, reducing the load on the building's electrical installation.
-
Installers and drilling companies – the monoblock design and lack of a need for a starting capacitor simplify installation in 400 V systems.
-
Wholesalers and technical storesthe 4" SKT series complements the range of 4-inch pumps in the three-phase power segment, as a power-equivalent counterpart to the SKM models, which operate on standard single-phase 230 V voltage.
Applications
The 4" SKT series is designed for drawing and pumping technically clean raw water from deep-water intakes and tanks for multifamily homes, farms, and service and industrial facilities equipped with a three-phase electrical installation. The pumps operate exclusively with water free of solid contaminants – the medium must not contain solid particles or abrasive substances that could damage the brass impeller and mechanical seal. The pumps are not water treatment devices – when using the water for other purposes, we recommend ensuring appropriate treatment.
The 4" SKT series submersible pumps operate in a vertical position, submerged to a maximum depth of 80 m. The permissible temperature of the pumped liquid is up to 35°C. The devices are compatible with standard pressure tanks and pressure control systems.

Frequently asked questions (FAQ) – 4" SKT submersible pump
How does the 4" SKT series differ from the 4" SKM, and when should you choose the 400 V version?
The 4" SKT series is the three-phase counterpart of the 4" SKM – both series have the same hydraulics and head parameters, but the 4" SKT is powered by 400 V. The three-phase motor draws significantly less current at the same power (e.g. 2.7 A instead of 10 A at 1.1 kW), reducing the load on the electrical installation. The 4" SKT is the right choice wherever a three-phase 400 V network is available – typically on farms, in service facilities, and in multifamily buildings.
Can the 4" SKT pump handle water containing sand or other solid contaminants?
No. The 4" SKT series pumps are designed exclusively for use with clean water. The presence of solid particles or abrasive substances may damage the brass impeller and mechanical seal. If the intake contains sand or suspended solids, install a filter upstream of the pump or choose a model designed for such conditions.
Does the 4" SKT pump require a starting capacitor or a starter box?
No – this is one of the practical advantages of three-phase power. 400 V motors start automatically without a capacitor, so there is no need to install an external starter box.
Where can I buy a Dambat 4" SKT submersible pump?
Dambat does not sell directly. 4" SKT series pumps are available from our trade partners, installation wholesalers, and authorized online distributors.
What are the warranty terms, and how can I contact the service department?
4" SKT series pumps are covered by a 24-month (2-year) Dambat manufacturer's warranty, calculated from the purchase date confirmed by the original proof of purchase. Warranty and post-warranty service: Adamów 50, Grodzisk Mazowiecki. Contact: tel. +48 22 632 86 09, e-mail: serwis@dambat.pl (Mon–Fri, 8:00–15:30).
