Amerigo - Non Clog Sewage Submersible Pump

NON-CLOG SUBMERSIBLE SEWAGE PUMPS : Submersible sewage pumps offer simple, the most economical and most reliable way of solving the pumping and disposal of sewage containing suspended solids. These compactly designed pumps are easy to handle and can be installed permanently with the help of automatic couplings in a small sump from where sewage is to be pumped or can be used for portable duty. Being submersible they do not require any pump house.

Bearings :The bearing arrangements with double angular contact ball bearings with deep groove ball bearings give the best resistance to the radial and thrust load combination in a centrifugal pump. The life rating is over 40000 hrs. The bearing are lubricated for life with a high temperature grease. Dry, squirrel cage 3 phase motor : The housing is totally dust & waterproof for submersible duty. The cooling is done externally and the special insulation ofthe winding takes care o{ rises in temperature during intermittent operations. Cable Joint : Special triple protection does not permit any liquid entry into the dry motor.

Moisture detection probe : The moisture detector indicates any moisture penetration into the motor.

Thermal Motor Protection : Built-in temperature sensors enable tripping of the motor if the temperature rises above 150 deg.C and restarts at 80 deg.C, giving complete dry run protection. Maximum permissible liquid temperature is 50 deg.C. Guide Device with single / double guide rail : The guide rail system for lowering and lifting the pump is an outstanding feature. The pump slides down on to the duck foot bend and engages with it without bolting. Profile Gasket : Ensures flexible, pressure tight and automatic connection between pump and duck foot bend.

Double Mechanical Seals : The pumps have as standard equipment double mechanical seals which seal off the motor from the pump section. The seal has seal faces made from silicon carbide for long life. The design of the oil chamber ensures efficient cooling of the seals. Energy saving impellers to suit different applications depending on the liquid, impellers may be semi-open or closed, running against a wear disc or casing ring. For industrial sewage, single channel, two channel or vortex impellers, can be used. Shaft with rotor : A shaft with a die-cast rotor on the motor side and a shaft protection sleeve on the pump side, ensures better life for the shaft. The compact seal arrangement has minimised shaftover-hang and consequently minimises shaft deflection. The motor portion is isolated from the pump by an intermediate casing with double mechanical seal in the oil chamber.

Non-clog submersible sewage pumps are of close coupled compact design and, having a pump below and a motor above, sump cleaning is possible to a maximum level. These are powered by squirrel cage induction dry motors suitable for operation at 4001440 volts, 3 phase, 50 Hz, AC Supply. Being submersible, they save a lot of costs on construction compared to other conventional pumps. They also are noise free in operation.
