Deep well electric pump Pedrollo 4BLOCKm4-8 up to 63 m, 0.75 kW

The Pedrollo 4BLOCKm4-8 is a high-performance monoblock submersible electric pump for 4-inch wells, designed for efficient water supply from deep sources in the domestic sector. It demonstrates outstanding sand resistance (up to 150 g/m³), making it an optimal choice for wells with a high content of solid particles.

Created as a new, more economical, and reliable product, the 4BLOCKm4-8 comes ready for installation, with a built-in capacitor, thermal protection inside the motor, and a 20-meter power cable. This significantly simplifies and speeds up the installation process, while providing the high head characteristics necessary for delivering water over considerable distances and heights.

Key Features and Advantages:

▪️Outstanding sand resistance: Effective operation with sand content up to 150 g/m³, ensuring pump durability. 

▪️Monoblock construction: A compact and reliable stainless steel solution, ready for immediate operation. 

▪️Patented hydraulic section: Innovative independent floating impellers minimize the impact of sand, significantly extending the pump's service life. 

▪️Improved energy efficiency: The minimum efficiency index (MEI) significantly exceeds the requirements of the ErP directive, which allows for a reduction in energy consumption (up to +12% compared to previous series).

High-Quality Components:

▪️Pump Shaft: AISI 304 stainless steel. 

▪️Impellers: Made of technopolymer. 

▪️Pump Bearings: Stationary part made of special technopolymer, rotating bushings and shaft made of AISI 316 stainless steel with chromium oxide coating for enhanced abrasion resistance. 

▪️Built-in check valve: For reliable protection against backflow.

 ▪️Automation: Built-in capacitor and thermal protection.

Application and Operating Limitations:

▪️Application: Ideal for supplying clean water from deep wells in the domestic sector, for automatic water supply systems with pressure tanks, and for irrigation. 

▪️Maximum Head: Up to 63 meters. 

▪️Pumped Liquid Temperature: Up to +35°C. 

▪️Maximum Immersion Depth: Up to 60 m (with a cable of appropriate length). 

▪️Maximum number of starts per hour: 30. 

▪️Operating Mode: S1 (continuous). 

▪️For wells with diameter: 4". 

▪️Connection port: 1 1/4".

The Pedrollo 4BLOCKm4-8 is a reliable and powerful choice for those who need an efficient and durable solution for water supply from deep wells, capable of operating even in difficult conditions.
