The DNA series is used for pumping biological liquids and sewage. The large free passage for solids makes it ideal for wastewater treatment plants, public and private sewage systems, and the livestock industry.
Characteristics
All main components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, located in an oil chamber, guarantees a long product service life.
Advantages of DNA pumps
The DNA sewage pump is an ideal solution for those looking for a professional product for use at home or in a small business. The free passage of the DNA sewage pump is the best alternative to pumps equipped with a macerator, which often becomes clogged, exposing the user to operational difficulties. The large free passage under the impeller for solids measuring from 45 to 80 mm (depending on the model) ensures long-term operation without the need for intervention. Open, six-blade Vortex impellers handle even fibrous sewage content perfectly, whereas macerators act like winding devices. Macerator blades quickly become blunt in sewage, act like wedges, and block the pump. Sewage pumps with such a large free passage beneath the impeller do not have these disadvantages. The impeller’s thick walls are sufficient for many years of operation in raw domestic sewage. The connection flanges allow installation with any coupling feet featuring holes according to DN standards.
When selecting a pump, check the parameters of the available pipeline, as the discharge pipe diameter or the terrain geometry may sometimes require the use of a higher power rating.
Control
The DNA sewage pump is available in four versions, combining single- and three-phase power supplies with control by an integrated float or an external signal. To control DNA pumps (except versions with an integrated float), we recommend the simple M121 (230V) controllers, as well as the M131 (400V). For more demanding users and two-pump pumping stations, we offer professional relay-and-contactor power and control panels in the SPP and SPS versions.
Installation methods
Thanks to the DN flange, DNA pumps are commonly installed on coupling feet in household, municipal, network, and stormwater sewage pumping stations. When the appropriate hose connection is used (an elbow ending in a plain end), they become portable drainage pumps for working with liquids containing large amounts of solids (gravel, sand, and waste). The DNA sewage pump can be used without difficulty to water a garden with rainwater, drain a flooded garage or basement, or pump water from a pond or ditch into another tank. DNA pumps have stable feet protruding from the pump body, allowing them to stand on level ground with sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA also comes standard with a 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
