Circulation pump unit Hewalex ALEX HX10 (DWZ) — compact pump assembly for domestic heating and hot water

Hewalex ALEX HX10 (DWZ) is a compact circulation pump unit designed for domestic heating and hot water systems. Supplied as a preassembled pump module, the unit integrates pump, flange fittings and connection points to simplify installation and commissioning. The assembly is intended for continuous circulation of heating water in boiler plants, heat exchangers and solar thermal loops where a ready-made pump solution reduces installation time and potential piping errors.

Advantages

The compact design of the ALEX HX10 (DWZ) reduces footprint and facilitates fitting in tight plant rooms or equipment cabinets. Factory assembly ensures correct alignment of hydraulic connections and minimizes on-site assembly work. The pump unit offers stable hydraulic performance for domestic circulation tasks and is compatible with standard pipework and control systems commonly used in residential heating and hot water installations.

Suitable for

• Domestic central heating circulation
• Domestic hot water recirculation loops
• Integration in small boiler plants and heat exchangers
• Solar thermal circuit circulation where a compact preassembled pump is required

Key specifications

• Compact pump assembly in a single preassembled module
• Designed for circulation of heating and domestic hot water
• Standard connection fittings for easy integration with existing pipework
• Suitable for continuous operation in residential systems
• Constructed for compatibility with common control and safety devices

How to use

Install the Hewalex ALEX HX10 (DWZ) in the circulation circuit following applicable local plumbing and heating regulations. Position the unit with correct flow direction and connect to the system pipework using the matching flange or threaded connections. Ensure electrical connections are made by a qualified electrician and that any control interfaces are integrated with the heating controller or differential temperature controller as required. Fill and vent the system according to standard commissioning procedures, then verify flow, pressure and temperature parameters before regular operation.

Usage recommendations

Use corrosion-inhibited water or heat-transfer fluid compatible with the pump materials, and implement routine maintenance checks including leak inspection, air bleeding and verification of electrical connections. For optimal lifetime and efficiency, follow manufacturer guidance for system water quality and scheduled servicing intervals.
