The Grundfos HS horizontal split case Centrifugal Pump is a single-stage, non-self-priming, between bearing, Centrifugal volute Pump. The axially split design allows easy removal of the top casing and access to the pump components (bearings, wear rings, impeller, and shaft seal) without disturbing the motor or pipework.
The HS Centrifugal Pump is ideal for custom applications and is available in a wide range of variants. The high efficiency and low life cycle costs make the HS ideal for any commercial building, water utility or industrial project.
The Grundfos HS is available in 3 configurations:
Pump with motor and base frame
Pump with base frame
bare shaft Pump only.
Features
Suction and discharge flanges are PN 16 according to EN 1092-2 (DIN2501)
Long-coupled with a totally enclosed fan cooled standard motor with main dimensions to IEC and DIN standards and mounting designation B3 (IM 1001)
The mechanical shaft seal has dimensions according to EN 12756
The rotating assembly is dynamically balanced according to ISO 1940 class G6.3
Impellers are double suction providing long operating, corrosion free life. Impellers are constructed in ASTM B584 bronze and are hydraulically balanced
The split-case construction enables removal and dismantling of the internal pump parts, e.g. bearings, wear rings, impeller and shaft seal, without disturbing the motor and pipework
Replaceable case wear rings protect the pump casing while reducing maintenance costs and maintaining high operating efficiencies
Pump and motor are mounted on a common base frame in the form of a welded, steel C-channel profile
Bronze shaft sleeves protect the shaft and help with fixation of the impeller.
Applications:
The Grundfos HS horizontal split case Centrifugal Pump is used in these applications:
Air-conditioning and chilled water system
Water condensing systems and cooling towers
District heating plants and heating systems
Process cooling and chilled water systems
Industrial heating systems
Wash down and cleaning systems
Public waterworks
Non-potable water systems
Field irrigation (flooding)
Sprinkler irrigation.
Benefits:
Easy to service: split case design
Many product variants available
High energy efficiency
Low life-cycle costs
Double volute reduces radial forces and minimizes noise and vibration
Independent bearing housing design allows access to the pump components without removing the top half of the casing
Double suction minimizes axial load, which extends the life of the wear rings, shaft seals and bearings.
