Wilo-Star-Z Pumps - Glandless Circulation Pumps

Wilo-Star-Z pumps are reliable, glandless circulating pumps with threaded connections for domestic water circulation systems in technice construction and industry. Thanks to their modern design and robust materials, such as bronze body, impeller plastic and ceramic shaft, they guarantee long-lasting and efficient operation under demanding conditions.

Key Applications

Wilo-Star-Z pumps are ideal for:

• Domestic water circulation systems in residential and commercial buildings,
• Industrial installations,
• Heating and cooling systems where constant water circulation is required.

Features and Equipment

The main features of Wilo-Star-Z pumps include:

• Operating modes: switchable speed steps (available in Star-Z...-3 versions) and manual setting of 1 or 3 speed steps.
• Equipment: keyed casting on the body (applies to Star-Z 25 models), ability to feed the power cord from both sides, and quick-connection with spring clamps.
• Safety: the motor is resistant to current when blocked, which increases the reliability of operation.

Technical Specifications

Typical designation e.g. Wilo-Star-Z 20/1 explains:

• Star: standard pump,
• Z: circulating pump,
• 20/: nominal diameter of the connection,
• 1: nominal head in meters (or other values depending on the model, such as "-3" for three-stage speed control).

Additional technical data:

• Operation with domestic water up to +65°C (short term up to +70°C),
• Supply voltage: 1~230 V, 50 Hz,
• Degree of protection: IP44,
• Maximum working pressure: 10 bar.

Materials and Scope of Delivery

Wilo-Star-Z are made of high quality materials for durability and reliability:

• Body: bronze,
• Impeller: plastic,
• Shaft: ceramic sinter,
• Bearing: sintered carbon, impregnated with resin.

The standard set includes a pump, gaskets (for threaded connection), installation and operation instructions. Accessories are also available, such as screw connectors, compensating elements, thermal insulation covers, as well as time control modules (e.g. Wilo-S1R-h, Wilo-SK 601N, Wilo-SK 602N) for time-dependent switching on and off of the pump.

Advanced Control

With optional control modules, Wilo-Star-Z pumps can be integrated into building management systems for precise control of unit operation and optimization of energy consumption. Versions with plug-in timer control modules are ideal for applications requiring precise operating schedules.
