CSC – Compact Split Case Pumps

CSC – Design Features

This range has been designed as the new generation of split case pumps for meeting the reliability and energy optimization needs of the expanding industrial, municipal and building services markets. Three major objectives for



Optimum Efficiency – Hydraulic Institute Standards & Europump Norms have been used as bench marks for acceptable minimum efficiency for this range.



Proven Hydraulic Designs – Established hydraulics have been used wherever the above benchmark has been met or exceeded.



Optimized Selection – A large number of frames help to find a pump operating close to “best efficiency point” for any duty cluster.



Double Volute Casing – This has been used as standard for all pumps with 100 mm NB delivery branch and above. Double volute construction eliminates radial loading and enhances seal, bearing and shaft lives when pumps are run at part flow condition.



Maximum Working Pressure – CI FG260 casing with PN16 flanges are used for working pressures up to 12 bar. Ductile Iron GGG50 casing with PN25 flanges are used for working pressures up to 20 bar. The design permits standard pre-engineered pumps to be used for both normal and high suction pressure applications.



Product Variants – Four Pre-engineered product variants are available:

building this new range have been: 

Optimum Efficiency



Highest Reliability



Smallest foot-print

CSC – Relative Advantages over conventional split case pumps 

Simple Design – Easy to dismantle and assemble.



Short Shaft Span – Reduces shaft deflection. Increases Bearing and Seal lives.



Simple Machining – Casing machining is simpler, faster and eliminates chances of errors.



Lesser Installation Space – Smaller foot-print releases expensive floor space for productive use.

CSC – Application Areas CSC pumps are ideal in installations where pumps are required for long, uninterrupted service with minimum of maintenance and where mechanical seal fitted pumps are a natural choice:

MS – Standard Pump – 12 bar working pressure HP – High Pressure – 20 bar working pressure



Industrial & Urban Water Supply

VE – Vertical Execution – 12 or 20 bar.



Air Conditioning

PG – Packed Gland Stuffing Box instead of mechanical seals.



Process Industry

These pumps will particularly benefit those pumping plants where energy costs constitute a significant part of the life cycle cost of the plant.



Low Shaft Stress & Shaft Deflection – Shafts have been designed to ensure low shear stress across the range and deflection of less than 0.05 mm at the stuffing boxes. This ensures vibration free operation and long seal / bearing life.

Pre-engineered Product Variants Δ MS - Standard Pump - 12 bar working pressure Δ HP - High Pressure - 20 bar working pressure Δ VE - Vertical Execution - 12 or 20 bar working pressure Δ PG - Packed Gland Stuffing Box instead of mechanical seals

Product Highlights Double entry impeller balances the axial thrust & ensures longer bearing & seal lives; low noise & vibration & greater reliability Easily renewable casing wear rings for maintaining proper running clearances for optimum pump efficiency. They are positively locked in place in the lower case to prevent rotation during operation Casing designed to withstand high working pressure & pressure surges with minimum of distortion. All casings are hydrostatically tested at 150% of maximum working pressure. True axial split case design for pressure boundary integrity. HP Version for high working pressure application

Large diameter shaft with shortest possible bearing span designed for minimum deflection for longer seal & bearing lives in the toughest service conditions. Precision machined & dowelled for accuracy during re-assembly after maintenance & parts replacement

Axially split case design allows easy removal of rotating assembly & inspection of components by removing top-half without disturbing pipe-work & alignment with the prime mover

Smooth water ways & fully machined exterior surfaces of impeller ensure high pump efficiency

Robust foot mounted design with suction & delivery flanges close to the pump feet provides protection against external forces & moments

Wide variety of mechanical seals are offered to suit specific application. Packed gland pumps are also available as option

Dust tight sealed for life deep groove ball bearings with average L10 life exceeding 100,000 hours for maintenance free pump operation .Option for external grease lubrication is also available

Double suction impeller enhances suction capability & reduces NPSH requirement of the pump Suction & discharge flanges are integrally cast into lower half casing ensuring high structural integrity when connected to the piping system & greater resistance to moments induced by nozzle loading Large diameter shaft with minimum possible bearing span ensures minimum shaft deflection & ensures long seal & bearing lives.

Double volute design has been adopted (for 100NB delivery branch & above) to reduce the radial thrust and is ideal when the pump is subjected to off-peak opearating conditions. Double volute construction ensures longer bearing & seal lives.

Compact Design 

Smaller footprint saves expensive floor space



Through bore arrangement reduces machining time and improves machining accuracy



Lesser number of parts makes maintainence easy in terms of dismantling & reassembly and management of spare parts
