Submersible pumps

4 inch submersible pump

The 4″ submersible pump (1x 220-230 V) with fixed cable (20, 30 or 40 meters) offers you reliable performance and high efficiency for your water pumping. It is easy to install.

Hydraulics

Our 4″ submersible pumps are equipped with a 1¼” riser connection. The casing and head of the hydraulic element are made of robust stainless steel, while the impeller and diffuser are made of durable technopolymer. We also offer the components in full stainless steel as an alternative. An integrated non-return valve provides additional safety. The removable stainless steel filter protects the pump from contamination and guarantees a long service life.

Motor

The pump motors (0.37 – 1.1 kW) operate with 1x 220-230 V ~ / 50 Hz and reach a speed of ~ 2,850 rpm. The IP 68 degree of protection guarantees maximum safety in underwater applications. The fixed cable is available in lengths of 20, 30 or 40 meters and complies with VDE and KTW standards. The motor is corrosion-resistant and can be operated in environments with temperatures of up to 40 °C. It also uses a food-grade lubricant that complies with the strict ISO 9001 standards. Alternatively, the motor is also available as a power version.

Well pumps

6-8 inch submersible pumps

Our 6″ and 8″ submersible pumps are the perfect solution for a wide range of applications, especially for equipping firefighting wells. These pumps offer a proven combination of high-quality EBARA submersible pumps and powerful Franklin submersible motors, which together guarantee efficiency and durability.

EBARA underwater pump

EBARA is known worldwide for manufacturing high-quality and reliable pumps. The 6″ and 8″ submersible pumps enable flow rates of 50 and 95 m3/h respectively. Both pumps offer very high performance. They are made of robust stainless steel and are characterized by their corrosion resistance and long service life.

Franklin submersible motor

The Franklin submersible motor is known for its robustness and durability. It offers outstanding efficiency and is designed for operation in demanding conditions. These motors are water-cooled and equipped with an integrated protection system that prevents overheating and damage due to dry running.

Versatile application possibilities

Our 6 inch and 8 inch submersible pumps are ideal for use in various applications including fire wells, agricultural irrigation systems, water supply facilities and industrial applications. Thanks to their high efficiency and reliability, they offer a cost-effective solution for your water pumping needs.

Submersible pumps

Submersible pumps accessories

Optimize the performance of your well pump with our high-quality accessories.

Motor cable

Our motor cables are specially designed for use with well pumps. They offer a high degree of flexibility and are resistant to moisture and mechanical loads. The cables are available in various lengths and cross-sections to ensure optimum adaptation to your specific requirements. They are VDE and KTW certified, which guarantees high quality and safety.

Shrink sleeves

Shrink sleeves are indispensable for a secure and watertight connection of motor cables. They offer excellent protection against moisture and mechanical stress, ensuring a durable and reliable cable connection. Our shrink sleeves are easy to install and offer high tensile strength and resistance to environmental influences.

Steel cable

We offer high-quality steel cables for the secure fastening and lowering of your submersible pump. These ropes are corrosion-resistant and extremely resilient, enabling the pump to be securely fixed in the deep well. Our steel cables are available in various lengths and diameters to meet the individual requirements of your project.

Rope clamps

We offer robust cable clamps to attach the steel cable to your submersible pump. These clamps are made of corrosion-resistant materials and offer high tensile strength. They ensure that the steel cable remains firmly and securely attached to the pump and well head, guaranteeing safe operation.

Pressure control for well pumps

Pumps Pressure control

Supplement your 4″ submersible pump with our high-quality pressure control units for efficient and reliable water delivery. These accessories offer you maximum functionality and safety when operating your pump.

Pressure control unit type Servopress

Voltage: 230 V~
Amperage: I = (16) 8A
Power: 1.5 kW
Degree of protection: IP 65
Maximum pressure: 10 bar
Connection: 1″

The Servopress pressure control unit ensures precise and reliable pressure control of your submersible pump. With a maximum operating pressure of 10 bar and a 1″ connection, it offers an ideal solution for various applications.

Pressure control unit type Servocontrol

Voltage: 230 V~
Amperage: I = (30) 16A
Power: 2.2 kW
Degree of protection: IP 65
Maximum pressure: 10 bar
Connection: 1¼”

The Servocontrol system is specially designed for more powerful applications. This system has an IP 65 degree of protection (splash-proof).

Important notes on installation

Both devices may only be installed in a vertical position. It is essential that you observe the selection criteria to ensure optimum function and safety. The pressure-dependent control unit is ready for immediate use and has a 1.5 meter extension cable including safety plug and coupling. These devices enable the automatic pressure-dependent activation and flow-dependent deactivation of your pump, which considerably simplifies operation.

Well pumps

Control box for fire extinguishing well

Switch boxes for fire extinguishing wells: Efficient power supply for submersible pumps.

Our switch boxes for fire wells are specially designed to ensure a reliable power supply for underground motor pumps.

The switch box can be equipped with a double locking system: On the left-hand side with a factory lock (2 keys included) and on the right-hand side for fire department locking (to be retrofitted by the operator).

The switch boxes are manufactured according to your specifications.

You have a choice:

  • Appliance plug: either 16 A / 400 V or 32 A / 400 Volt
  • Housing with motor protection switch: optionally adjustable to 10-16 A, 16-25 A or 25-32 A
  • Switch variants: optional main switch (on/off) or mains zero emergency current

Important notes

The plinth installation depth is marked on the connection pillar. To prevent condensation forming on the installation equipment in the column, fill the lower part of the column with a base filler. The electric cables (submersible pump/mains) may only be connected by a qualified electrician. The tripping current of the motor protection switch must be set to the rated current of the intended motor. The direction of motor rotation (rotating field direction “right”) must be checked and documented before handover. Our switch boxes offer you the flexibility and safety you need for the reliable operation of your fire extinguishing system.
