In-line twin-head pump with two single-stage glanded centrifugal pumps in the same housing with switchover valve, for pipe installation or installation on a base. Housing blind flange and mounting brackets available at additional charge. Low-vibration and low-noise monobloc design with lantern and rigidly connected standard flange motor (standard motor). With forced-flow circulation, bidirectional bellows mechanical seal and cavitation-reducing impeller. Flanges with pressure measuring connections R 1/8. The pump housing and lantern are cataphoretic-coated.
Motors in IE3 technology as standard. Pump with motor ≥ 5.5 kW are equipped as standard with a PTC thermistor sensor for motor protection.
The motor terminal box ≤ 7.5 kW can be made of metal or plastic. If a metal terminal box is absolutely necessary, please order the appropriate special variant. The motor terminal boxes > 7.5 kW are always made of metal.

High performance is our strength. Entrust the Wilo commissioning-service with ensuring a smooth process when implementing new systems in your installations. We will happily accompany you throughout the commissioning process of our products and support you step-by-step. You will benefit directly from the advantages of our products and their performance in operation. Our qualified service technicians will familiarise you with all strengths to guarantee a safe and optimal start. Why you should take advantage of our commissioning expertise: The pump is part of a complex supply system, that is why the focus of professional installers during commissioning is primarily on the higher-level system technology. However, the optimal pump settings – as a part of the overall system – are crucial for energy consumption and therefore for the efficiency and operational reliability of the entire system. The advantage of using professional installers is that they hand over a system to the customer which is energy efficient from the start and they do not have to acquire detailed knowledge of each control and pump series for this. This significantly reduces both energy costs and pump wear. The commissioning service provided by the Wilo service also includes instruction of the responsible building service engineer. | |||
