Submersible water pump 400 W 140 l/min for dirty water PF0410

Application and Performance in Challenging Conditions

A 400 W device has been designed for efficient dewatering of areas where contaminated liquid accumulates. With a maximum flow rate of up to 140 liters per minute, the pump handles rapid emptying of cellars, wells, pools, or garden ponds. It is important to note the water head, which is 5 meters – this parameter determines how high water can be pumped from ground level.

Crucially for the installer and end user, the device does not require manual supervision during operation. Equipped with a float switch, it automatically cuts off power when the water level drops below a safe threshold (approx. 40 mm). This simple yet effective protection safeguards the motor against overheating and damage resulting from dry running.

Operation with Contaminants and Structural Durability

Dirty water often carries sediments, leaves, or other small objects. This pump accepts solid particles up to 35 mm in diameter, significantly expanding its application beyond clean rainwater. There is no need to filter the tank contents before starting the device – simply immerse it in the water collection area.

The device construction meets the IP68 standard, meaning full protection against dust and the possibility of prolonged submersion in water (up to a depth of 5 m). The 10-meter power cord provides great flexibility in selecting the connection point to the power source without the need for additional extension cords. The entire unit weighs only 4.3 kg, facilitating transport and handling during installation or removal in hard-to-reach locations.

Summary of Key Features

The key parameters of this model have been selected to ensure high performance efficiency under various conditions:

• Rated power of 400 W provides sufficient drive force for typical dewatering tasks.
• Maximum flow rate of 140 l/min enables rapid emptying of large tanks in a short time.
• Water head of 5 m allows pumping liquid even to higher floors or directly into the sewage system.
• Ability to pass solid particles up to 35 mm in diameter eliminates the risk of clogging in the presence of small debris and sediments.
• Protection class IP68 guarantees full tightness allowing constant contact with water and dust.
• Power cord length (10 m) increases installation convenience without the need for additional electrical accessories.

The device proves itself where reliability is required alongside resistance to harsh environmental conditions. Automatic water level control eliminates the risk of human error during continuous operation.
