The DNA series is used for pumping biological fluids and sewage. Its large free passage for solids makes it ideal for wastewater treatment plants, public and private sewer systems, and the livestock industry.
Specifications
All main components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, located in an oil chamber, ensures long product 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 DNA sewage pump’s free passage is the best alternative to pumps with a macerator, which often clogs and causes operational difficulties for users. The large free passage beneath the impeller, for solids measuring 45 to 80 mm (depending on the model), ensures long-term operation without intervention. Open six-vane Vortex impellers handle even fibrous sewage contents with ease, while macerators act like winding reels. Macerator blades, which 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 drawbacks. The impeller’s thick walls are suitable for years of operation in raw domestic sewage. The connection flanges allow installation with any guide rail coupling bases with DN-pattern holes.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or terrain geometry may sometimes require a higher-powered pump.
Control
The DNA sewage pump comes in four versions, combining single- and three-phase power with control by an integrated float switch or an external signal. To control DNA pumps (except versions with an integrated float switch), we recommend the simple M121 controllers M121 (230 V) and M131 (400 V). For more demanding users and two-pump pumping stations, we offer professional power and control panels with relay-contactor control SPP and SPS.
Installation methods
Thanks to their DN flange, DNA pumps are often installed on guide rail couplings in residential, municipal and network sewage pumping stations, as well as stormwater pumping stations. With a suitable hose connection (an elbow with a plain end), they can be used as portable drainage pumps and to handle 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 into another tank. DNA pumps have stable feet that protrude 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 models come standard with a 10-meter power cable. They work perfectly with DRENO guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
