The DNA series is used for pumping biological liquids 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. Double mechanical seals in a back-to-back configuration, housed in an oil chamber, ensure a long product life.
Advantages of DNA Pumps
The DNA sewage pump is an ideal solution for anyone looking for a professional-grade 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 operating problems. The large free passage beneath the impeller accommodates solids measuring 45 to 80 mm (depending on the model), ensuring long-lasting operation without the need for intervention. The open six-vane Vortex impellers handle even fibrous sewage contents with ease, while macerators act like winders. Macerator blades quickly become blunt in sewage, 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 ensure years of operation in raw domestic sewage. Connection flanges allow installation with any coupling feet with DN-sized openings.
When selecting a pump, check the specifications of the available pipeline, as sometimes the diameter of the discharge pipe or the terrain geometry requires a more powerful pump.
Control
The DNA sewage pump is available in four versions, combining single-phase and three-phase power supplies 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 residential, municipal and network sewage pumping stations, as well as stormwater pumping stations. When fitted with a suitable hose connection (an elbow with a plain end), they become portable drainage pumps for liquids with a high solids content (gravel, sand, debris). A 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 that protrude from the pump body, allowing them to stand on a level surface with enough clearance beneath the body for water intake.
Like all DRENO sewage pumps, DNA pumps also come with a 10-meter power cable as standard. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
