Submersible water pump 300 W 140 l/min for clean water PF0300

Application and Performance in Daily Tasks

A compact submersible pump with a power rating of 300 W is designed for rapid and efficient removal of clean water. With a flow rate of up to 140 liters per minute, it serves not only as a permanent installation component but also as a mobile emergency tool. The device enables water extraction from flooded basements, garages, or other rooms, as well as water intake from wells for household purposes or garden irrigation. A maximum lift height of 7 meters provides sufficient head to raise water to upper floors or to retention tanks, making it a versatile solution for single-family homes and small enterprises.

Construction and Resistance to External Conditions

The housing, made of durable plastic, ensures the device's light weight (4.2 kg without the cable) while maintaining the rigidity required for operation under demanding conditions. A key structural feature is the protection class IP68, indicating complete sealing and the ability to remain submerged in water for extended periods without risking motor damage. This design eliminates the need for continuous monitoring of the water level—the pump can operate even when fully submerged. Note the permissible particle size of 5 mm; although the device is intended for clean water, short-term presence of small solid particles should not pose a problem for the impeller, provided they do not exceed the specified limit.

Installation and Practical Usage Aspects

For the installer and end-user, the device's readiness for immediate operation is crucial. The long power cable, measuring 10 meters, significantly facilitates installation in locations distant from the power source, eliminating the need for additional extension cords that could become a source of failure or hazard. The device dimensions (160 x 168 x 305 mm) allow for easy storage and transport in standard car trunks or toolboxes.

Technical specifications influencing the selection of the device for specific tasks should be analyzed in the context of real-world scenarios:

• With a rated power of 300 W, the device achieves an optimal balance between energy consumption and pumping force necessary for typical household tasks.
• A flow rate of approximately 140 l/min enables rapid emptying of tanks or rooms (theoretically around 8400 liters per hour).
• A lift height of up to 7 m allows water to be raised to upper building floors or to fill above-ground tanks.
• The 10 m power cable enables direct access to a socket without requiring additional extension cords, even in deep wells or flooded basements.
• The IP68 protection class guarantees complete resistance to dust and water, which is essential for safe operation of a fully submerged unit.
• The permissible particle size of 5 mm indicates that the device is primarily intended for clean water, though it tolerates the presence of small solid particles not exceeding this dimension.

This device is a "plug & play" solution—once lowered into water and connected to the electrical network, it starts automatically (or upon manual activation of a float switch, if purchased separately). The rigid housing protects the interior against impacts with well walls or tank bottoms, extending the device's service life during regular use.
