The DNA series is used for pumping biological liquids and wastewater. The large free passage for solids makes it ideal for wastewater treatment plants, public and private sewer systems, and the livestock industry.
Characteristics
All major 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 the ideal solution for anyone 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 with a macerator, which often becomes clogged, exposing the user to operational difficulties. The large free passage beneath the impeller for solids measuring 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 wastewater contents perfectly, whereas macerators act like winding devices. Macerator blades quickly become blunt in wastewater, acting like wedges and blocking the pump. Sewage pumps with such a large free passage beneath the impeller are free from these drawbacks. The impeller’s thick walls are sufficient for many years of operation in raw domestic wastewater. Connection flanges allow installation with any coupling feet featuring DN-pattern holes.
When selecting a pump, check the parameters of the available pipeline, as the diameter of the discharge pipe or the terrain geometry may sometimes require the use of greater power.
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 (230 V) controllers, as well as the M131 (400 V). For more demanding users and dual-pump pumping stations, we offer professional relay- and contactor-based power and control switchboards, SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are commonly installed on coupling feet in domestic, municipal, network, and stormwater pumping stations. With a suitable hose connection (an elbow ending in a plain end), they become portable pumps for drainage and for handling liquids with a high solids content (gravel, sand, 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 to another tank. DNA pumps have stable feet extending from the pump body, allowing them to stand on level ground while providing sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA comes standard with a 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
