CSC – Compact Split Case Pumps

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

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:

Industrial & Urban Water Supply

Air Conditioning

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.

CSC – Design Features

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:

MS – Standard Pump – 12 bar working pressure

HP – High Pressure – 20 bar working pressure

VE – Vertical Execution – 12 or 20 bar.

PG – Packed Gland Stuffing Box instead of mechanical seals.

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.

Casing designed to withstand highworking pressure & pressure surgeswith minimum of distortion. All casingsare hydrostatically tested at 150% ofmaximum working pressure. True axialsplit case design for pressure boundaryintegrity. HP Version for high workingpressure application

Easily renewable casing wear rings formaintaining proper running clearancesfor optimum pump efficiency. They arepositively locked in place in the lowercase to prevent rotation duringoperation

Double entry impeller balances theaxial thrust & ensures longer bearing& seal lives; low noise & vibration &greater reliability

Wide variety of mechanical seals areoffered to suit specific application.Packed gland pumps are alsoavailable as option

Dust tight sealed for life deep grooveball bearings with average L10 lifeexceeding 100,000 hours formaintenance free pump operation .Optionfor external grease lubrication is alsoavailable

Double suction impeller enhancessuction capability & reduces NPSHrequirement of the pump

Suction & discharge flanges areintegrally cast into lower half casingensuring high structural integrity whenconnected to the piping system &greater resistance to momentsinduced by nozzle loading

Large diameter shaft with minimumpossible bearing span ensuresminimum shaft deflection & ensureslong seal & bearing lives.

Double volute design has beenadopted (for 100NB delivery branch &above) to reduce the radial thrust andis ideal when the pump is subjected tooff-peak opearating conditions. Doublevolute construction ensures longerbearing & seal lives.

Large diameter shaft with shortestpossible bearing span designed forminimum deflection for longer seal &bearing lives in the toughest serviceconditions.

Axially split case design allows easyremoval of rotating assembly &inspection of components by removingtop-half without disturbing pipe-work &alignment with the prime mover

Precision machined & dowelled foraccuracy during re-assembly aftermaintenance & parts replacement

Smooth water ways & fully machinedexterior surfaces of impeller ensure highpump efficiency

Robust foot mounted design withsuction & delivery flanges close to thepump feet provides protection againstexternal forces & moments
