curo centrifugal multi-stage pumps -...
TRANSCRIPT
These locally manufactured pumps have been designed and are constructed from materials suitable for most high pressure applications.
The range consists of the LTF and LTS models, all of Which are available in different sizes of inlet and outlet branches with varying number of stages.
Generally the LTF models are used when direct coupling is required to three phase motors running at 2 pole motor speed (approximately 2960 RPM) and the LTS models are used when direct coupling is required to three phase motors running at 4 pole motor speed (approximately 1480 RPM).
However, both models are suitable for operation at various other shaft speeds e.g. when direct coupled to diesel engines or when driven via speed reduction gearboxes.
The LTP and LTS models are designed to cover heads varying from approximately 40 meters to 600 meters, flows from 2 litre/sec to 250 litre/sec.
These horizontal, high pressure centrifugal pumps are of the multi-ring section design. All pumps are built up from any number of stages held between the Suction Cover and Delivery Cover by Body Bolts. Sealing of casing components is by means of '0' Rings. Pump rotation is clockwise when viewed from the drive end.
The LTF and LTS pumps are either fitted with grease lubricated ball bearings or roller bearings and thrust discs.
Standard materials of construction for the LTF and LTS pumps are cast iron casing components, cast iron or bronze impellers, cast iron diffusers and return channels and high tensile steel shafts.
