“MBH” Submerged Centrifugal Pumps offer simple, the most economical and most reliable way of solving the pumping water. “MBH”s rich experience over several years in the field of designing and manufacturing of varieties of pump sets has built up technical know-how and expertise in designing of reliable and efficient pumps which need practically no maintenance. These compactly designed pumps are easy to handle and can be installed permanently with the help of horizontal standard / automatic couplings in a small sump from where water is to be pumped or can be used for portable duty. Being submersible they do not require any pump house. Pump is designed to handle clear & raw water in the canal, river or dam site.

PUMPSET FEATURES :

• • The motor is submersible squirrel cage, induction type and dry type with class ‘F’ or ‘H’ insulation and IP 68 enclosure fitted with ball bearing & mechanical sealing to ensure in high depth submergence condition. It is rated for 415 ± 10% V, 3ph 50 ± 5% C/S A.C. supply.
  • Winding with ‘H’ class insulation*(withstanding winding hot spot temperature upto 185°C respectively) while the nominal  temperature rise of winding hot spot will not exceed of class ‘B’.
  • Common shaft of pump and motor is fitted with angular contact ball or roller bearing gives the best result. (Minimum life of ball bearing is 75000 hours in accordance with BS 5512.)
  • The pump casing is volute casing which is suitable both horizontal / vertical installation. The impeller is mounted directly to the extended motor shaft.
  • The impeller has narrow passage with multi channel enclosed type (except specific speed ≥4500 USCS – where semi open
    impellers are used) and designed for high efficiency.
  • The motor’s Rotor is dual cage copper bar brazed type/aluminium die cast.
  • Thermal overload protectors (bimetallic over load relays) is embedded in each phase of stator windings to detect overheating and trip the motor, from control panel while temperature exceeds above 130° C.
  • Moisture sensor also provides to detect primary mechanical seal’s leakage.
  • Oil chamber is provided for cooling and lubrication of mechanical seal (tandem). The primary (inboard) seal is of silicon carbide or tungsten carbide  faces to withstand  erosive wear due to any  silt particles. The secondary (outboard) seal of carbon v/s cast chrome molybdenum steel or silicon carbide or tungsten carbide
