Materials
|
Casing |
.In-line axially split design which permits removal of the complete rotor without moving the pipe and motor. .Short distance between bearings. .Leak-tight due to compact joint flange with long, prestressed bolts. .Counter-rotation possible with similar parts. .Double volute casing reduces radial forces on the impeller and consequently the bearing loads. .Easy mounting self-aligning upper casing. .Flange drilled to ISO, DIN, BS or ANSI. .Smooth surface inside and epoxy coating as required. .Replaceable wear rings protect the casing at the impeller running clearances. .Heavy duty casing design for high working pressure. |
|
Impeller |
.Computer- Optimized double entry impellers. .Minimal axial thrust due to double-entry impeller. .Impeller is statically and dynamically balanced according to ISO1940. .Optional impeller wear rings. |
|
Seal |
.Asbestos-free, potable water quality softpacked stuffing boxes. .Unbalanced mechanical seal, according to DIN 24960. .Balance mechanical seal for operating pressure＞16 bar on required. .Cartridge-type mechanical seal on required. |
|
Bearing |
.SKF covered, sealed for life grease lubricated antifriction bearings for long service life. .Open gland, enough space for service activities. .Optional: oil lubrication with constant level oiler. .Horizontal: grease lubricated ball bearings on both side, oil lubrication is optional.For the big size, sliding bearing is available. .Vertical: grease lubricated ball bearing. |
|
Shaft |
.Heavy duty shaft completely sealed and dry for zero corrosion. .Short and rigid with negligible vibrations. .No threads exposed to pumped medium, long operating life and no corrosion. .Adjustment-free assembly. .Quick and easy assembly/dismantling of the rotor components due to elastically prestressed mountings. .Maximum interchangeability shafts design entire series for 2900 rpm and 1450 rpm model just six shafts and six bearings assemblies. |
Key Components and Operating Principle
Between-the-bearings pumps are characterized by their robust construction and dual-bearing setup, which supports the impeller at both ends. Key components include:
Impeller: The impeller, central to the pump’s operation, is mounted between bearings on either side. This design ensures balance and minimizes axial loads.
Shaft and Bearings: The shaft is supported by bearings at both ends, providing stability, reducing wear, and enhancing the pump’s longevity.
Volute: The volute (casing) can be either axially split (splitting horizontally, parallel to the shaft axis) or radially split (splitting vertically, perpendicular to the shaft axis and parallel to the impeller). The choice depends on pressure requirements and maintenance considerations.
Shaft Seals: Shaft seals are located where the rotating shaft passes through the pump casing. Their primary function is to minimize fluid leakage and prevent air from entering the pump. Depending on the application, seals may range from simple packing glands to advanced mechanical seals.
Suction and Discharge Ports: These ports allow fluid to enter and exit the pump at the appropriate pressure and flow rate. Positioned on either side of the bottom half of the casing, they allow the top half to be removed easily, providing access to the impeller for maintenance.
