## Long description

The WILO IPH-W 20/160-1,1/2 inline pump is a compact centrifugal circulation pump designed for integration into heating, cooling and hot-water systems. Its in-line casing enables direct installation into pipe runs, saving space and simplifying plumbing work. The pump is intended for building services and industrial circulation tasks that require reliable liquid transport in a small footprint.
Advantages
The inline design reduces installation complexity by aligning with existing pipework and minimizes required installation space. The centrifugal impeller provides steady flow and stable hydraulic performance across typical operating ranges for heating and cooling circuits. Durable construction materials and an engineered motor ensure continuous operation and reduced maintenance intervals. Its compact dimensions and standardized flanged/union connections make it suitable for retrofit jobs as well as new installations.

Key specifications
 Pump type: inline centrifugal circulation pump
 Nominal connection: inline pipe connection suitable for standard heating systems
 Application: heating, cooling and hot-water circulation
 Design: compact, space-saving in-line casing for direct installation into pipe runs
 Performance characteristics: designed for continuous circulation duties with stable flow and head within typical hydronic ranges

How to use
Install the pump in-line with the system piping following the flow direction marked on the casing and ensuring proper alignment to avoid pipe strain. Provide appropriate isolation valves and a service bypass to allow maintenance without draining the entire system. Observe recommended electrical connections and protection for the motor as specified by a qualified electrician. Prior to commissioning, flush the circuit to remove debris, vent trapped air, and check for correct rotation and leak-tight joints. Adjust operating parameters such as flow rate and control settings according to system design requirements.
Usage recommendations
Use corrosion-inhibited, water-based heat transfer media and keep fluid temperature and pressure within the pump's rated operating range. Schedule periodic inspections for leaks, bearing noise and electrical connections. During long shutdowns, protect the pump from freezing and purge if required. For replacements or retrofits, verify pipe dimensions and connection compatibility to ensure straightforward installation.
