4" SKT 200 - 400 V peripheral submersible pump
The 4" SKT series consists of monoblock peripheral submersible pumps with a 4" diameter and a three-phase 400 V power supply, featuring a brass impeller and brass ports. Designed for installations that require higher power with low current draw - available in 1.1 and 1.5 kW models with a 15 m cable terminated with a plug.
Who it's for
-
Farms and industrial facilities - the 400 V power supply and greater delivery head (up to 120 m) make it possible to serve deeper wells and meet higher water demand at facilities with a three-phase electrical system.
-
Owners of multi-family homes and commercial 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 system.
-
Installers and drilling companies - the monoblock design and lack of a start 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 supply segment, as an alternative to the SKM models with comparable power, which run on standard single-phase 230 V voltage.
Applications
The 4" SKT series is designed for drawing and pumping clean, untreated water from deep wells and tanks for use in multi-family homes, farms, and commercial and industrial facilities equipped with a three-phase electrical system. The pumps operate only with water free of solid contaminants - the liquid must not contain solid particles or abrasives that could damage the brass impeller and mechanical seal. The pumps do not treat water - if it is to be used for other purposes, we recommend ensuring it is suitably treated.
The 4" SKT series submersible pumps operate in a vertical position and can be submerged to a maximum depth of 80 m. The maximum temperature of the pumped liquid is 35°C. The units work 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 to the 4" SKM series – both series have the same hydraulics and head performance, but the 4" SKT is powered by 400 V. A 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 system. The 4" SKT is the right choice wherever a 400 V three-phase supply is available – typically on farms, in commercial premises, and in multi-unit residential buildings.
Can the 4" SKT pump pump water containing sand or other solid contaminants?
No. 4" SKT series pumps are designed exclusively for use with clean water. The presence of solid particles or abrasives can damage the brass impeller and mechanical seal. If the water source contains sand or suspended solids, install a filter before the pump or choose a model designed for such conditions.
Does the 4" SKT pump require a starting capacitor or 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 to customers. 4" SKT series pumps are available from our sales partners, plumbing 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, starting 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, email: serwis@dambat.pl (Mon–Fri 8:00–15:30).
