Armstrong Fluid Technology 516860-020 Pump Accessory
The Armstrong Fluid Technology 516860-020 is a high-performance centrifugal pump suction guide designed for seamless integration into commercial HVAC and industrial piping systems. This SG-43 suction guide serves as a multi-functional fitting, performing the duties of a 90-degree elbow, a strainer, and a flow stabilizer all in one compact unit. Featuring a 4" flanged system side and a 3" flanged pump side, it effectively reduces the footprint of your mechanical room by eliminating the need for long straight pipe runs before the pump inlet. The rugged cast iron body and cast iron guide vanes ensure maximum durability and laminar flow, protecting the impeller from turbulence and debris. Rated for a 175 PSI working pressure and an operating temperature of 230 degrees F, this component includes a fine mesh galvanized steel start-up strainer to remove construction slag and particulates during initial system operation, ensuring long-term reliability for your hydronic pumping system.
- Space-Saving Design: Combines multiple fittings into one, significantly reducing installation space and material costs.
- Enhanced Pump Protection: The integrated suction strainer prevents damaging debris from entering the pump casing.
- Optimal Flow Dynamics: Internal guide vanes straighten fluid flow, improving pump efficiency and reducing vibration.
- Robust Construction: Built with heavy-duty cast iron to withstand high-pressure commercial plumbing environments.
- Maintenance Friendly: Features a removable cover for easy access to the strainer element without disturbing piping.
Common Questions
How do I install the SG-43 suction guide?
The unit should be bolted directly to the pump suction flange. Ensure the guide vanes are aligned correctly to stabilize the flow before it enters the impeller.
What is the purpose of the start-up strainer mesh?
The fine mesh captures small particles during the initial system flush. It is typically removed after the system has been cleaned to prevent excessive pressure drop during normal operation.
Can this unit be mounted in any orientation?
It is designed for horizontal or vertical installation, provided the blow-down port or drain plug is accessible for cleaning and maintenance.
