The DNB series is used to pump and drain clear liquids and gray sewage. The special geometry of S-FLOW rotors allows you to press the liquid with the content of suspended solids with short fibers and are perfect for sewage treatment plants.
Characteristic
All main components are made of gg20 cast iron. The double mechanical seal in the Back to Back configuration, placed in the oil chamber, guarantees long product durability.
Advantages of pumps for DNB dirty water
Dirty water like rainwater or gray sewage For example, from a shower, washing machine or sinks (without solid fractions and faeces) do not require rotors with free flights because they do not contain elements that can block the flow or wrapped on it. Therefore, we can use much more efficient rotors than Vortex or open channel for their pressing. DNB dirt pumps have been designed specifically for high efficiency with a large flight through the S-FLOW rotor channels, but at the same time using the relatively low power of electric motors.
Use of DNB pumps
Highly efficient S-FLOW rotors find a number of applications in pumping stations rainwater, light sewage (gray), mechanically cleaned sewage, technological waters, slurry, leakage and sewage treatment plant. Electric pumps for dirty DNB water have legs on which they can stand freely on the ground and the collar for attaching the connection or clutching hook DRENO type: AND, B Whether Long. The DNB model offers one and three -phase models with or without a built -in swimmer depending on the control method preferred by the recipient.
Control
DNA sewage pump has four versions that are a combination of single and three -phase power supply and a built -in swimmer and an external signal. We recommend simple drivers to control DNA pumps (except for versions with a built -in swimmer) M121 (230V) and also M131 (400V). For more demanding users and two pumping pumping stations, we offer professional power supply switchgears in the relay and unit. SPP and SPS.
Installation methods
Thanks to the DN collar, the DNB pumps are eagerly installed on coupling feet in rain pumping stations as well as precipitated sewage and technological water. When using a suitable hose connection (knee finished with a barefoot end), we get a portable pump for dehydration and work with liquids with a high content of solids (gravel, sand, garbage). We can water the garden with rainwater with a dnb sewage pump, dehydrate the flooded garage or basement, and pump water from the pond or ditch to another tank. DNB type pumps have stable legs protruding from the pump body, on which they can stand on an even ground ensuring the adequate ground clearance under the body for water supply.
Like any sewage pump DRENO, DNB also has a 10 -meter power cord as standard. They work perfectly with coupling feet DRENO: Duty 65, and B4 pn10.
