Wita HE - 180 mm solar pump

Product description

The Wita HE 180 mm solar pump is a reliable and efficient solution for replacing existing solar and heating systems. Without integrated speed control, this pump is ideal for conventional operation of an older system with an adapted solar controller configuration.

With a clear focus on smooth operation, the pump offers practical features that facilitate installation in older systems and ensure reliable supply.

Technical details

The pump has a length of 180 mm and is suitable for pipe diameters of DN 25 and threads G 1½ ". This ensures easy integration into existing installations.

With the ability to switch between two performance levels for different delivery heads—4 or 6 meters—the solar pump adapts flexibly to individual requirements. At a height of 4 meters, it achieves a flow rate of up to 2800 l/h with a power consumption of 3 to 25 watts, while at 6 meters, a flow rate of 3600 l/h is achieved with a power consumption of 3 to 45 watts.

Energy efficiency and operation

The stated energy efficiency index is a maximum of 0.20, demonstrating optimized energy utilization. This enables economical operation, which is particularly important in the solar sector.

The adjustment of the solar controller is particularly important: If the solar pump is used as a replacement solution, it is important to set the controller to 100% power to ensure proper operation. In addition, the night-time setback function ensures energy-saving operation during setback times.

Characteristic curves and operating modes

The Wita HE solar pump offers a total of three constant curves, two constant-pressure curves, and two proportional curves. These diverse operating modes allow for demand-based control of performance and adaptation to different system types.

With this range of control options, the pump is versatile and can operate consistently reliably under varying operating conditions.

Design and quality

The pump housing is coated with a protective cataphoresis treatment, which improves corrosion protection and supports the longevity of the device. The motor head, finished in RAL 9006 white and made of aluminum, underscores the pump's modern, high-quality design.

Additional quality features such as the integrated LED display with the WITA logo, two seals in the 1"-area as well as specially designed socket connectors round off the overall package and offer safety and ease of use.

Installation and accessories

Installation of the pump is straightforward thanks to the included MB instructions and pre-installed insulation. This ensures quick and efficient installation in existing systems.

The versatile accessories and sophisticated design of the Wita HE 180 mm solar pump make it an attractive solution for users who value reliability and easy integration.
