Inline Metallic Coupled Type

Description 

The IL-1150 Centrifugal Vertical In-Line Metallic Coupled Pump is a space-saving, end-suction style vertical in-line centrifugal pump engineered for clean-water and utility-water circulation duties where compact footprint, stable hydraulic performance, and direct pipeline installation are required. Its metallic volute casing, flanged suction/discharge connections, and close-coupled motor arrangement provide a rigid, low-maintenance pumping package suitable for mechanical rooms, plant rooms, process utility skids, and marine auxiliary systems. 

 

Designed for continuous circulation and pressure boosting, the IL-1150 supports HVAC chilled-water loops, condenser-water circuits, heating and boiler-feed circulation support, washdown systems, and commercial/industrial water distribution. The vertical in-line configuration reduces floor-space demand compared with base-mounted horizontal pumps while maintaining service access to the motor, coupling area, mechanical seal, and rotating assembly. 

 

 

Technical Key Features 

• Vertical in-line configuration for direct pipe mounting and reduced plant-room footprint. 

• Coupled pump construction enables efficient power transmission and easier motor serviceability. 

• Metallic hydraulic casing suitable for clean water, treated water, glycol-water mixtures, and utility water services. 

• Suitable for continuous-duty circulation in commercial buildings, industrial facilities, and marine auxiliary systems. 

• Mechanical seal compatibility supports clean-water operation with optional elastomer and face-material upgrades. 

• Flanged suction and discharge ports provide rigid installation for HVAC, fire support, and industrial circulation networks. 

• Back pull-out service concept allows inspection of rotating components with minimal pipe disturbance, where design clearance is provided.

Verification Note 

The operating limits and material options above are inferred from standard vertical in-line centrifugal pump practice for clean-water HVAC, utility, and marine auxiliary services. Final values should be verified against the IL-1150 manufacturer curve, GA drawing, motor rating, flange standard, and project duty point before procurement or publication.
