• Very high efficiency in the operating range
• Good suction performance and low NPSH
• Stable characteristics
• Minimum maintenance required
• Vibration free performance
• Highest reliability
• High degree of interchangeability of components
Pump Casing :
Horizontal axially split volute type, suction and discharge nozzles and supporting feet are cast integral with lower half casing.
Impeller:
Double or single suction type accurately balanced. In the case of double suction impellers, the hydraulic thrust is balanced automatically because of pressure equalization on both sides of the impeller.
Shafts:
The high tensile steel shaft accurately machined and ground is supported by antifriction bearings. The shaft is protected by shaft sleeves from wear in stuffing box area.
Stuffing Box :
Can be sealed by gland packing or by mechanical seal and is suitable for liquids having temperature from (-) 8°C to 90°C. In special cases packing or mechanical seal can be offered upto 120°C.
Bearings:
Deep groove ball bearings are provided. Standard lubrication is grease.
Direction Of Rotation :
Standard: Clockwise viewed from driving end. Optional: Anticlockwise viewed from driving end.
Drive:
Suitable for coupling with electric motors, l.C. engines or steam turbines either directly or through belt drives.
Flanges:
Standard: Drilled to BS: 4504 PN 16 F. F.
Optional: DIN 2533, ND16, BS 4504, PN 25ASA 125/150
