VEVOR LPS25-4BP-180 high-efficiency hot water recirculation pump, 220 V, 22 W, flow rate up to 50 l/min, EMC automatic circulation pump with 38 mm (1½″) NPT threaded connection, for water heating systems

Features and Details

High performance and energy efficiency: Replacement part number: 25-40/180. Equipped with an ECM permanent magnet motor, this high-efficiency circulation pump reduces energy loss by utilizing electronic commutation technology. Max. flow rate 50 l/min, head 4 m, while ensuring lower electricity costs and high heating efficiency. The 38-mm threaded connection allows for easy replacement of existing pumps in water heating systems. (Energy efficiency class: A)

Intelligent control modes: Equipped with five smart modes—automatic, constant speed, constant pressure, proportional pressure, and night mode. The cast-iron circulation pump automatically adjusts its operation to meet your needs, optimizing the heating system’s performance, increasing comfort, and reducing energy consumption.

Low noise level: Equipped with a permanent magnet motor with a copper core, the hot water recirculation pump operates exceptionally quietly—the noise level does not exceed 45 dB. The absence of carbon brushes and slip rings reduces mechanical wear, ensuring a quiet environment even near underfloor heating zones.

Durable construction: A high-efficiency circulation pump with a durable cast iron housing is designed to operate in a water temperature range of 2 to 110 °C. The pump housing’s insulating jacket reduces heat loss in the circulation system, increasing overall efficiency. High-quality materials ensure reliable and long-lasting operation, reducing maintenance frequency and costs.

Versatile accessories: The set includes two cast iron adapters (38 mm × 25 mm) and rubber O-rings, ensuring the pump’s compatibility with the most commonly used pipe diameters. Suitable for both new installations and replacement of existing equipment, ensuring convenient and flexible use.

Equipped with an ECM permanent magnet motor, our pump utilizes electronic commutation and high-efficiency magnetic materials, ensuring consistently high efficiency and significant energy savings. Five intelligent control modes and a built-in check valve allow this pump to fully meet the needs of a heating system.

The integrated smart control system with an ECM motor ensures automatic adjustment and optimized performance. It allows for convenient control and monitoring of the high-efficiency circulation pump’s operation, ensuring a higher level of automation and ease of use.

Equipped with a permanent magnet motor, this cast-iron circulation pump provides precise speed control and excellent flow regulation, making it ideal for applications that require high precision and performance.

Equipped with two durable rubber O-rings, this hot water recirculation pump prevents leaks at connection points, protecting the heating system from water damage and helping to avoid unnecessary repairs or water loss.

Ensure that the circulation pump is installed in a dry environment with an effective drainage system. This prevents potential property damage caused by water leaks and helps maintain optimal performance.
