Drainage cell (drain pump) DVP
Drainage cells DVP are used primarily for automatic watering easily soiled and moderately aggressive wastewater, including storm water and groundwater.
Pumped liquid may contain up to 5% of particulate matter other than a long fiber.
Drainage cells was performed as a complete unit mounted on a square steel plate, which is placed directly on collecting a well with an opening 500 x 500 mm.
The basic components of cells are single stage pump, motor and control panel.
Electric motor mounted on a steel plate and a pump submerged in the pumped liquid are connected by an extended shaft and bearing pipes.
Control panel contains elements of automation, protection and signaling. Control panel may be installed on the steel plate (as shown), but it is recommended to be placed on the wall of the room near the pump.
The pump is designed to work in manual and automatic mode.
The automated drain station is controlled by level switch, which signals for starting and stopping of electric motors get through the level probei.
In case of danger from the occasional massive influx of waste water, it is possible to supply the pump with two-speed motor (1400 / 2800 rpm). When the water level reaches the critical point automatically triggers greater speed and sound and light alarm. At a speed of 2800 rpm the flow is increased about 2 times.
The material used for making pumps are cast iron SL 250, stainless steel C 4171, galvanized steel pipes and polyacetal of whom made bearing cartridge.
