Wilo-MEDANA CV1-L.204-1/E/A/10O high-pressure vertical water pump 4240460

Wilo-MEDANA CV1-L.204-1/E/A/10O pump is a high-pressure vertical pump designed for efficient and reliable water pumping in various applications. The pump's construction, based on solid materials such as stainless steel, guarantees long service life and corrosion resistance. Thanks to its compact dimensions and vertical design, the pump is easy to install even in limited spaces.

Performance and application

This pump is characterized by a capacity of up to 3.88 m³/h and a maximum head of 36.48 m, making it ideal for water supply systems, irrigation, and industrial processes requiring water pressure boosting. The 0.55 kW motor provides stable operation and efficient energy use – the motor's energy efficiency class is IE2. The motor speed is 2900 revolutions per minute. The pump is designed to operate with water temperatures up to 120°C, expanding its range of applications.

Construction and materials

A key element of the pump is the stainless steel casing (grade 304 – 1.4301), providing high corrosion resistance and durability. The impeller is also made of stainless steel (grade 304 – 1.4301), further increasing the device's lifespan. Inlet and outlet connections with external cylindrical gas threads (BSPP) with a diameter of 1 inch (25 mm) facilitate integration with existing hydraulic installations – both connections meet the ISO 228-1 standard. The flange connection pressure class is PN 16, guaranteeing safety during operation at a maximum working pressure of 10 bar. The IP55 protection class protects the pump from environmental influences, allowing it to operate in various conditions.
