The DNA series is used for pumping biological fluids and sewage. Its large free passage for solids makes it ideal for treatment plants, public and private sewer systems, and the livestock industry.
Specifications
All major components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, housed in an oil chamber, ensures long product life.
Advantages of DNA pumps
The DNA sewage pump is the ideal solution for anyone looking for a professional product for home or small business use. The DNA sewage pump’s free passage is the best alternative to pumps with a macerator, which often clogs and causes problems during operation. The large free passage beneath the impeller, for solids measuring 45 to 80 mm (depending on the model), ensures long-lasting operation without the need for intervention. Open six-vane Vortex impellers handle even fibrous sewage exceptionally well, while macerators act like winding mechanisms. Macerator blades quickly become dull in sewage, acting like wedges and blocking the pump. Sewage pumps with such a large free passage beneath the impeller do not have these drawbacks. The impeller’s thick walls are built for years of operation in raw domestic sewage. The connection flanges allow installation with any guide rail coupling feet with 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 a more powerful pump.
Control
The DNA sewage pump is available in four versions, combining single- and three-phase power supply with control by a built-in float switch or an external signal. To control DNA pumps (except versions with a built-in float switch), we recommend the simple M121 controllers M121 (230 V), as well as M131 (400 V). For more demanding users and dual-pump pumping stations, we offer professional power and control panels with relay-contactor control: SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are commonly installed on coupling feet in domestic, municipal, network and stormwater sewage pumping stations. When used with a suitable hose connection (an elbow with 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 to water the 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 housing, allowing them to stand on level ground with sufficient clearance beneath the housing for water intake.
Like every DRENO sewage pump, the DNA also comes with a 10-meter power cable as standard. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
