Drainage submersible pump Pedrollo TOP 3

Drainage submersible pump Pedrollo TOP 3

Brief technical characteristics

• maximum application depth up to 3 m, below water level
• maximum liquid temperature up to +40 °С (liquid temperature up to +90 °С for up to 3 minutes)
• maximum passage of suspended solids up to 10 mm
• maximum emptying level up to 14 mm from the bottom

Principle of operation

The TOP series includes submersible drainage electric pumps, centrifugal type with an open impeller, designed to operate in automatic mode. The impeller, oscillating on the drive shaft, consists of a rear disc and blades. Through the suction grate, the liquid enters the rotating blade channel; here the fluid acquires a radial movement from the center to the periphery, during which it acquires energy both in the form of pressure and in the form of an increase in flow velocity. At the outlet of the impeller, the liquid rushes into a spiral, after converting part of the kinetic energy into pressure energy, it leaves the pump through a vertically mounted supply pipe provided in the discharge casing. Proper engine cooling is provided by the pumped liquid.

Scope and installation

TOR series pumps are recommended for lifting clean water without abrasive particles. The design solutions used ensure ease of operation and safety even in continuous operation (eg in fountains), thanks to the complete cooling of the engine, which is provided with a good power reserve and a double mechanical seal. Easy dismantling of the motor and pump makes maintenance and repair simple and convenient. These pumps are especially suitable for dehumidification of flooded rooms of small volume, in emergency situations, such as (rooms, cellars, boxes), for emptying swimming pools, bathtubs and aquariums, for the treatment of domestic wastewater, (washing machines and dishwashers), for supplying water to garden fountains, for irrigating small gardens and orchards and "storage tanks, for draining small sewage pits.

Structural features
