Design Features
- Horizontal or vertical manufacturing option. Axial split case, single stage, double suction centrifugal pumps.
- Suction and discharge flanges are on the same axis on the bottom casing. Split case design permits easy disassembly of the rotor group for maintenance or repair without distorting pump alignment and suction / discharge piping.
- Suction and Discharge Flanges are comform to EN 1092-2/PN 16 or PN25. (EN 1092-1 / PN 16 or PN 25 for steel or stainless steel casing)
Pump Designation
- All impellers are balanced dynamically or statically according to ISO 1940 class 6.3.
- Impeller is of double suction design. This feature increases pump suction performance in addition with providing the balance of hydraulic axial forces resulting higher bearing lifes and higher reliability.
- In standard construction, the direction of rotation is clockwise when it is looked from drive end. In this case, suction flange is on right and discharge flange is on left.
- Upon request the direction of rotation can be reversed. This time the position of the suction and discharge flanges are also reversed.
- Grease lubricated ball bearings are used in horizontal installation. In case of vertical installation, pumping liquid lubricated journal bearings on top and grease lubricated ball bearings on bottom are used.
Shaft sealing
- Depending on request or requirement, pumps with soft packing or single, double and cartridge type mechanical seals can be supplied.
