The PIUSI EX50 DC is an extremely versatile and robust direct current (DC) fuel transfer pump, specifically designed for the safe transfer of flammable liquids such as gasoline, kerosene, and diesel (including HVO/XTL fuels). The device complies with the strictest international safety regulations, especially in environments where potentially explosive atmospheres may exist.
This compact yet high-performance pump offers an ideal solution for mining and construction sectors, industrial facilities, and marine applications where a reliable and certified DC power source is available.
The PIUSI EX50 DC pump offers a combination of safety, durability, and ease of use:
Robust and Compact Design: The pump has a cast iron housing, which guarantees a long service life and mechanical resistance even under the harshest operating conditions.
High Flow Rate: It ensures a flow rate of up to 50 liters/minute while operating with reduced power consumption, contributing to the pump's longevity.
Easy Maintenance: Thanks to the flanged components, the pump, flow meter, and filters can be installed or replaced quickly and safely, even without using sealant.
Integrated Protection: It features built-in thermal protection to prevent overheating. The metal suction filter protects the pump from contaminants and foreign objects.
Alacsony Zajszint: The integrated noise suppressor (EMC electromagnetic compatibility) ensures the convenient and quiet operation of the EX50 DC.
UL Listed Motor Optional: Also available in certain configurations with a UL listed motor, increasing its applicability in international markets.
The PIUSI EX50 DC pump complies with the latest ATEX directives concerning the use of materials in potentially explosive atmospheres. This strict compliance ensures that the pump can be safely used for transferring flammable liquids, preventing explosions caused by sparking inside the pump or in the surrounding atmosphere.
Certifications:
ATEX Certificate: CESI12ATEX033X
IECEx Certificate: IECEx CES12.0016X
This certification portfolio reinforces PIUSI's commitment to developing systems for the transfer of explosive liquids.
The EX50 DC pump is ideally suited for dispensing from various types of tanks. The table below details the key technical parameters:

The flexibility of the PIUSI EX50 DC pump allows for a wide range of applications:
Construction and Mining: Fuel replenishment in hard-to-reach areas where 12V DC power supply is available.
Industrial Sites: Safe transfer of flammable materials inside closed systems.
Agriculture: High-performance yet mobile solution for refueling from fuel tanks.
Marine Applications: Can also be used on boats and at marina facilities due to its appropriate certifications.
Although the EX50 DC denotes the 12V DC version, the PIUSI EX50 series is also available in an AC (alternating current) version, allowing the user to match the choice to the available power source. The pump can be purchased standalone or as part of complete transfer kits, including flow meters and filters.
Detailed datasheets and technical documentation (including ATEX and IECEx certifications) are available from the manufacturer's sources, providing further in-depth information for installation and maintenance. The PIUSI EX50 DC is the benchmark for safe and efficient flammable liquid handling.
