The DNA series is used to pump 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.
Characteristics
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 a long product 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 DNA sewage pump’s free passage is the best alternative to pumps with macerators, which often become clogged and cause operational problems. The large free passage beneath the impeller allows solids measuring 45 to 80 mm (depending on the model) to pass through, ensuring long-term operation without intervention. Open six-vane Vortex impellers handle even fibrous sewage contents with ease, whereas 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 wastewater. The connection flanges allow installation with any coupling feet with DN-sized openings.
When selecting a pump, check the specifications 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 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 the M131 (400 V). For more demanding users and dual-pump pumping stations, we offer professional power and control panels with relay-contactor controls, the SPP and SPS.
Installation methods
Thanks to their DN flange, DNA pumps are popular choices for installation on guide rail couplings in domestic, municipal and network sewage pumping stations, as well as stormwater pumping stations. With a suitable hose connection (an elbow with a plain end), they become portable drainage pumps for handling liquids with a high solids content (gravel, sand, debris). The DNA sewage pump can be used to water the garden with rainwater, drain a flooded garage or basement, and pump water from a pond or ditch into another tank. DNA pumps have stable feet that extend from the pump body, allowing them to stand on a level surface with sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA also comes with a standard 10-meter power cable. They work perfectly with DRENO guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
