Business Profile
Pleuger submersible pump units are one- or multistage centrifugal units which operate below water level and are driven by waterfilled three-phase asynchronous induction submersible motors*. Pumps and motors form a single enclosed unit. The units are installed below the water level in deep wells, caissons, tanks etc. The pumps are equipped with a non-return valve to guarantee optimal functional safety (water hammer).
Pleuger submersible pump units are vertically connected to a discharge pipe at the nonreturn valve or discharge casing. Pleuger submersible pump units can be offered for a wide range of applications. Pumps are available with capacities up to
6000 m3/h (26000 gpm) and heads up to 800 m (2600 ft).
Pleuger submersible pump units are designed and manufactured to the highest quality with high pump efficiencies and long working life under the most adverse conditions. They are extensively tested and inspected to ensure operational safety. Pleuger submersible pump units are designed on the principle of a modular structure to ensure an economical manufacturing process. In addition to this, different tailor-made units can be offered. Pleuger submersible pump units provide
economic solutions for almost every user requirement.
高质量的潜水泵和motorproductionrequires both, specialized know-how and continually evolving
manufacturing processes. All submersible pump products are produced using the most advanced manufacturing techniques – from initial CAD development to quality-controlled
CNC production. It is not by chance that among experts Pleuger has been a byword for excellence since
decades.
PLEUGER submersible motors provide successful and reliable service since 1929. The three-phase AC squirrel cage induction motors1 are water / glycol filled (65 volume % potable water and 35 volume % glycol). The water / glycol motor filling provides lubrication of motor bearings and motor cooling. The mixture is environmentally safe and prevents freezing of the motor filling liquid, while mitigating corrosion. The motor windings consist of fully waterproof / high di-electric strength windings (PVC, PE2+PA or special insulating material for special applications). The insulation class of the motor winding is Y (90°C) according to IEC. The motors can be rewound. The electrical power supply is provided by a submersible cable, directly connected to the winding. The power and signal cable(s) are sealed at the motor with special designed cable glands. The dynamically balanced rotor is guided in oversized twin bearings in each bearing housing (top and bottom of motor). An internal breather diaphragm in the lower motor housing provides pressure & volume compensation and ensures, that the motor is operating without differential pressure. A high-quality mechanical seal prevents the ingress of ambient liquid into the motor, fully protecting the motor against contamination. A high-quality selfaligning thrust bearing allows high thrust and a long bearing life, even under the heaviest pump duty conditions. PLEUGER submersible motor designs are available for vertical or horizontal installations. In maintaining our reputation as a leading supplier of pumping systems for the water industry, PLEUGER Industries continues improve PLEUGER submersible motors.
