Strainer for suction basket - for BRA.T5.000 - 2 in; L=85 mm BRA.51.000

Product detailed description

This strainer is used in industrial and commercial heating, plumbing, and pump systems to filter debris from the fluid before it reaches the check valve. It is commonly installed in systems where the suction basket is part of the return line, such as in circulation pumps, boiler feed systems, and condensate return lines. The device ensures that particulate matter is prevented from entering the check valve mechanism, which could otherwise cause wear, blockage, or failure. The strainer is designed for use in closed-loop systems where the media is typically water or condensate, and the operating conditions are moderate in terms of temperature and pressure.

Installers and technicians working on heating or pump systems will find this component essential in maintaining the integrity of the check valve. It is typically installed at the inlet of the check valve, where it captures solid particles before they reach the internal components. The device is suitable for use in systems with internal thread sizes from 2 in to 4 in F, and its compact length of 85 mm allows for installation in tight spaces. The strainer is designed to be durable and resistant to corrosion, making it suitable for long-term use in industrial environments.

Technical parameters

Material	Stainless steel AISI 316
Weight	0.066 kg
Code	51000200
Brand	IVAR

The material used, AISI 316 stainless steel, is selected for its resistance to corrosion and its ability to maintain structural integrity in aggressive environments. The mesh size of 1.2 mm ensures that fine particles are filtered out while allowing the fluid to pass through with minimal resistance. The connection size of 2 in to 4 in F allows for compatibility with a range of pipe sizes and fittings. These parameters are important for ensuring that the strainer is correctly sized for the system and that it can handle the expected flow rates and particulate load.

Installation and connection

Installation of the strainer involves connecting it to the internal F thread of the suction basket or pipe. The device is designed for screw-on installation, and the nylon thread helps to prevent leaks and ensure a secure connection. The installer should verify that the internal thread size matches the strainer's connection size (2 in to 4 in F) before installation. A common mistake is to install the strainer without checking the thread compatibility, which can lead to leaks or improper sealing. The device should be tightened evenly to avoid damaging the nylon thread or the stainless steel body. Once installed, the strainer should be checked for any signs of leakage or misalignment.

Compatibility and accessories

This strainer is specifically designed for use with the BRA.T5.000 and BRA.51.000 check valves. It is compatible with internal F threads in the size range of 2 in to 4 in. No additional accessories are required for installation, as the device is self-contained and does not require gaskets or seals. However, it is important to ensure that the check valve and suction basket are compatible with the strainer's dimensions and material. There are no related products listed for this item.

Technical background for designers

The strainer operates by allowing fluid to pass through the mesh while retaining solid particles. The mesh is made from a fine stainless steel grid with 1.2 mm openings, which is sufficient to capture most particulate matter without significantly restricting flow. The AISI 316 stainless steel material is selected for its resistance to corrosion and its ability to maintain structural integrity in aggressive environments. The device is integrated into the system as part of the suction line, where it acts as a first line of defense against particulate contamination. The service life of the strainer is influenced by the quality of the fluid and the frequency of maintenance. In systems with high particulate load, the strainer may need to be cleaned more frequently to maintain efficiency.

Service and operation

Regular inspection and cleaning of the strainer are necessary to maintain its effectiveness. The mesh should be checked for blockage and cleaned if necessary. No specific service intervals are provided, but it is recommended to inspect the device during routine system maintenance. The nylon thread should also be inspected for wear or damage, as this can affect the seal. If the strainer becomes clogged or damaged, it should be replaced to prevent particulate matter from entering the check valve. There are no specific service procedures outlined in the brief.

Frequently asked questions

Can this strainer be used with internal F threads larger than 4 in?
No, the device is designed for internal F threads ranging from 2 in to 4 in. Larger threads are not supported.

Is the nylon thread sufficient for high-pressure applications?
The nylon thread is suitable for standard pressure conditions. For high-pressure applications, additional sealing measures may be required.

Can the mesh be replaced separately?
There is no information provided on whether the mesh can be replaced separately. The device is likely designed as a single unit.

Is the strainer suitable for use with condensate?
Yes, the strainer is suitable for use with condensate, as the material and design are appropriate for this type of fluid.
