Portable centrifugal monoblock submersible pumps Dwarf

Portable centrifugal monoblock submersible pumps DWARF
The purpose and design submersible drainage pump DWARF:

The pump DWARF submersible drainage is a portable monoblock consisting of electric motor and pump (centrifugal pump). Drive pumps is a three-phase induction motor or a single-phase capacitor induction motor. The pump part is separated from the motor system seal with oil chamber. Pumps in single-phase version ( 220V) are manufactured with built-in level sensor (float switch) and without level sensor.

The pump GNOME is designed for pumping dirty water temperature up to 35 °C (Tr - 60 °C) and a density of 1100 kg/m3, when the solid content of mechanical impurities up to 10% by weight with a density of solid particles not more than 2500 kg/m3 and a maximum size of up to 5 mm

The pumps are not designed for operation in explosion hazard areas.
Applications submersible drainage pump DWARF:

* pumping water out of basements and areas when flooding
* pumping of groundwater and flood waters from excavations in construction
* irrigation and drainage in agriculture
* wastewater from washing machines and installations for washing machines
* in treatment facilities
* in technological processes

The advantages of submersible drainage pump DWARF:

1. Easily removable for cleaning the filter.
2. High reliability and long service life.
3. Excellent quality of materials used.
4. Easy maintenance and operation.
5. A high efficiency.
6. Allow operation over the entire range of pressure characteristics.
7. Instanoe open impeller provides a stable parameters.


Installation of submersible drainage pump DWARF:

Working position of pump vertical, it must be entirely in the water for reliable cooling of the motor Immersing the pump in the water must be made by means of the cable to eliminate tension on the power cable. Installation of the pump on the object can be produced as a stationary, rigid pipe with flexible and mobile.
Legend submersible drainage pump DWARF:

For example,

The pump Dwarf 10 - 10 Tr 380 THAT 3631 - 025-05747979-2003,
where Gnome is the trading name;
10 - rated flow, m3/h;
10 - nominal head, m,
4 - no symbol for water temperatures up to 35 0C,
Tr-for water temperature up to 60°C, if the Tr is not necessary for water temperatures up to 35°C;
380V - rated voltage, V.

The symbol of the pump in single-phase execution if the order should be:

The pump Dwarf 10 - 10 D, 220 THAT 3631 - 025-05747979-2003,
where Gnome is the trading name;
10 - rated flow, m3/h;
10 - nominal head, m,
E - with a level sensor (float switch), if D is not without level sensor;
220 - rated voltage, V.
