Pump fitting, 1" x 6/4"

Product detailed description

This pump fitting is designed for installation with circulation pumps in central heating and water supply systems. It provides secure and leak-free connection between standard piping and pump inlets, typically found in residential and commercial buildings. The fitting is commonly used during pump replacement or system expansion to ensure correct alignment and sealing.

The 1 inch x 6/4 inch size allows transition between different pipe configurations. The internal thread ensures compatibility with standard pump connections. The CW617N brass construction offers corrosion resistance and mechanical strength for long-term operation under thermal stress.

The operating temperature limit of +110°C makes this fitting suitable for high-temperature heating circuits. The PN16 rating indicates it can handle pressures up to 16 bar at normal operating temperatures. These values are critical when selecting components for systems with elevated thermal or hydraulic loads.

Installation and connection

To connect the pump fitting, align the internal thread with the pump inlet and secure using a tightening nut. Ensure the mating surface is clean and free from debris before tightening. Use a wrench to apply even torque until the connection is firm. Check the alignment with adjacent piping to avoid stress on the joint. Common installation errors include over-tightening, which can damage the sealing surface, and using incorrect thread sealant, leading to leakage or corrosion.

Compatibility and accessories

This fitting is specifically intended for use with Avansa circulation pumps. When replacing or servicing the pump, it is recommended to order two pieces of the fitting to cover both inlet and outlet connections. Additional components such as pipe unions, sealing rings or pipe clamps may be required depending on the system configuration and installation method.

Technical background for designers

CW617N brass is a lead-free alloy known for its machinability and resistance to dezincification in hot water environments. The fitting operates as a transitional element between pipe and pump, ensuring fluid continuity and minimizing flow restrictions. The internal thread design allows for accurate positioning and minimises misalignment risks. System performance depends on correct sizing and compatibility with the pump’s inlet requirements. Prolonged exposure beyond the specified operating temperature can affect material integrity and sealing effectiveness.

Service and operation

Periodic inspection is recommended to detect signs of wear or leakage. Check the tightness of the connection and look for corrosion around the threads. Replace the fitting if any damage or deformation is observed. No specific service interval is defined in the technical documentation.

Frequently asked questions

Can this fitting be used with non-Avanza pumps?
If the pump inlet matches the 6/4 inch thread specification, the fitting is compatible regardless of the pump brand.

Is sealing compound required for the connection?
A thin layer of thread sealant is optional but not mandatory. Avoid using aggressive compounds that could react with the brass material.

What is the maximum allowable working temperature?
The fitting is rated for continuous operation at up to 110°C. Exceeding this temperature may compromise sealing and structural integrity.

Can this fitting be used in open-loop systems?
Yes, provided the system does not exceed the specified pressure and temperature limits and the medium is compatible with brass CW617N.
