FOREWORD
“SV INDUSTRIES” rotary pump type “SVX” is a self priming bi-directional positive displacement gear pump in simple two priece cast iron construction with single helical modified profile carbon steel gears shrunk fitted on alloy steel hardened & ground shaft as gear firmly supported on 4 nos of self-lubricated sintered bronzebush bearing. The pump can be run in either direction with change in inlet-outlet port position. The relief valve operations can be reversed by simply changing theR.V. parts on opposite side.
MATERIAL OF CONSTRUCTION
- Body & covers : IS 210 FG 220 C.I.Grade
- Drive & shafts : EN-19 Hardened & ground
- Gears : EN-8
- Bush-Bearing : Sintered bronze
- Seals : Oil seal
- Key for coupling : Mild steel
SPECIAL NOTES
- For calculating power requirement, multiply unit HP per kg pressure with duty point pressure & add no load viscous HP of appropriate viscosity, adequate margin may be provided to this Higher /lower rating motor can be employed based on duty point power requirement than what is specified as above Bracket in different height available to match the height of electric motor.
- “SVX” series pumps are designed to run at 1440 RPM up to viscosity of 500 CST, or higher viscosity it is desirable to reduce for size above11/4”. Performance at low speed is always advantageous as it improves efficiency reduces noise level & NPSH & enhances operational life, capacity willreduce in proportion to the speed.
USES
Due to simple, compact design & with availability of mono-block version these pumps are ideal for OE application of engine lubrication, pumping & heating units,oil filtration, cleaning & cooling system. The pump can also be used for general pump application to handle viscous liquid such as fuel oil, lube oil, LSHS,mineral oil, transformer oil, LDO, paints, varnish, glue, glycerine, soap solutior, sugar solution & molasses.
