END SUCTION PUMPS SERIES - ESL

Rooted in experience

Product Application

• Range Coverage – A total of 31 pumps provide optimum coverage of dutiesfor flows beyond ISO2858 end suction pumps.

• Hydraulic Design – Extensive use has been made of proven hydraulicsfrom our established split case pumps to build this range. The hydraulicperformance is characterized by stable head-capacity curve, high efficiencyand low NPSHr.

• Mechanical Design – All high head pumps incorporate double volute designto reduce radial load and to improve seal/bearing lives. Combination ofcylindrical roller and BECB matched pair angular contact bearings ensureshigh bearing life under all load conditions.

• Clockwise rotation is standard while CCW rotation canbe provided on request.

• Customized suction branch orientation• Centerline Mounting• Oil Lubricated Bearings• Varieties of mechanical seal options• Many Material Options• Short Bearing bracket with product lubricated bush

bearing ahead of the impeller.

Acceptance TestsAcceptance test & QA documentationThe following QA documents are available onrequest for all pumps:1) Mill Test report for casing and impeller –

Physical / Chemical Certificate.2) Ultrasonic Test (ASTM-A-388) for shafts3) Dynamic Balancing report for impeller – ISO

1940 Gr.6.34) Hydrostatic Pressure test certificate5) Performance test certificate as per ISO

100% SPEED = 1500 RPMGD VALUE = 4 Kg-m 22

The above speed-torque characteristicsshows the variation of torque with speed during pump start up. The curve can be usedto estimate the starting time of the electricmotor.

SHAFT SEALINGThe pumps are offered with two basic versions:a) Packed Glandb) Mechanical Seal

Packed Gland Pumps- Usually five packing ringsare used with two rings towards the impeller endand three rings towards the gland end with a lanternring interposed between two sets of packings. Thepackings are mounted on renewable shaft sleeves.Shaft packing are offered in variety of materials de-pending on the characteristics of the liquid handled.

Mechanical Seal fitted Pumps- These are offeredwith

a) Single unbalanced sealb) Single balanced seal

The selection of mechanical seal is done based onthe pump application and a very large variety of sealoptions are available. Double mechanical seals canbe supplied on request. Additionally, variety of sealpiping as per API 684 are offered for special applications.

Shaft seal: Gland Pack
