Product Information

Construction :

MBH Polder pumps are portable pumping units which have pump below and motor above construction. These are powered by squirrel cage induction motors suitable for 400/440 volts, 3 phase, 50 Hz AC supply, totally enclosed. The motor windings are water and oil resistant and ingress of water or moisture inside the motor due to seal failure or other reason will not render the pump inoperative. The pump motor unit is of close coupled construction and the double casing design provides on effective water cooling of the motor by water flowing around the motor casing the motor is sealed by special mechanical seal so that the pumping media like River water, screened storm water, muddy and sandy water does not enter the motor chamber and damage the motor. All parts are made from specially selected material and processed to ensure long life under arduous operation conditions.

MBH polder pump sets are available in water filled, cooled & lubricated designs.

Advantages :

MBH Polder pumps are of simple and robust design and can withstand rough handling at construction sites and any other heavy duty applications. After installation, the MBH pump helps itself. Under normal conditions, these pumps require much less attendance before service in other words cost of labour is reduced to a minimum pumps have high overall efficiency and that means low power costs. MBH Polder pumps can be operated in series to achieve higher heads.

Application :

MBH polder pumps are particularly suitable for nonclog operation to handle muddy as well as sandy water. They are used to pump out water from the lowest levels such as Dewatering of building construction sites, dam sites, narrow trenches, pits and shafts, mines, difficult to approach sumps, for flood control, firefighting and other purposes, where waste water disposal is necessary. These also find use for pumping work in ship building yards, Dewatering ash laden water in thermal power plants and tube mills.

Accessories :

The following accessories are normally supplied as extra with pumps.

  1. Cable synthetic rubber oil and water proof.
  2. 3 core - 4 core of suitable size, as per requirement.
  3. Delivery hose pipe, flexible of suitable size as requirement.
  4. Coupling pump flange to hose pipe.
  5. Control Panel.
  6. Water Level Guard
