LBH Series

The LBH series are High Speed monoblock pumps.

  • Pumps shall be designed to withstand voltage drops to 320 volts.
  • Better insulating materials are used so that monoblock can withstand high temperature rise.
  • High operating efficiencies of the monoblock result into greater water discharge rate and lower power bills.
  • The “back pullout” facility enables the monoblock to be serviced without disturbing the pipe work. 
  • All components are manufactured from materials as per standard specification. They are precisely machined on modern machine tools to give you years of reliable operation.
  • All Monoblock windings are vacuum impregnated with sybthetic varnish for bettermoisture resistance.
  • All rotating components and assemblies are dynamically balanced to ensure long bearing life and vibration free smooth operation.
  •  All monoblock are fully tested as per the specification prior to dispatch.

 

MDH Series

The MDH series are Centrifugal Monoblock Pumpset. 

  • The laminations are non-oriented silicon steel & confirms to IS-648.
  • Volute, Impeller, Adaptor, Stator body, Endshield shall be made of close grained cast iron of high tensile strength and has a very smooth surface finish resulting in low friction losses.
  • Motor windings shall be vacuum impregnated with synthetic varnish for better moisture resistance.
  • Superior mechanical shaft seal for longer life and effective sealing against water leakage.
  • The electric rotor is pressure die cast & uses electric grade aluminium.
  • Grease Lubricated anti-friction ball bearings shall be fitted at both ends to withstand radial and axial loads.
  • They are precisely machined on modern machine tools to give you years of reliable operation.

 

LBI Series

The LBI series are cost competitive, non-self-priming, horizontal, single-stage, end-suction, compact centrifugal pumps with predominantly cast iron construction.

  • The pump casing shall have material of construction of Cast Iron FG 260 (standard supply), Bronze LTB2, CF8, CF8M, axial suction and radial discharge port, dynamically balanced impeller, steel shaft, stainless steel shaft sleeve.
  •  The Pump shaft sealing shall be by mechanical shaft seal of Carbon/Ceramic/NBR/AISI 304 construction suitable for 10 bar pressure rating and water temperature from 0 to +90 deg. C.
  •  The pump shall be close coupled with a totally enclosed fan cooled type (TEFC) Induction motor, with F class insulation, S1 duty and IP55 protection, suitable for 3 phase 415 volts, 1 phase, 230 volts power supply.
  •  The pump shall have back pull out design so as to enable the rotating parts to be removed and serviced without dismantling the suction and discharge pipe work.
  •  All cast iron parts shall be CED (cathode electrode deposition) coated for corrosion resistance with uniform coating and controlled deposition thickness of 20-30 microns.
