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.
Features
All major components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, housed in an oil chamber, guarantees a 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 macerators, which often clog and cause operating difficulties. The large free passage beneath the impeller handles solids measuring 45 to 80 mm (depending on the model), ensuring long-term operation without intervention. The open, six-vane Vortex impellers handle even fibrous sewage contents with ease, whereas macerators act like winding reels. Their blades quickly become blunt 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 ensure 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 specifications of the available pipeline, as the diameter of the discharge pipe or the terrain may sometimes require a more powerful pump.
Controls
The DNA sewage pump is available in four versions, combining single- or 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 simple controllers M121 (230 V), as well as M131 (400 V). For more demanding users and dual-pump pumping stations, we offer professional relay-contactor power and control panels: SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are frequently installed on guide rail couplings in domestic, 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 pumps for drainage and pumping 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, and pump water from a pond or ditch into another tank. DNA pumps have stable feet that protrude from the pump body and allow them to stand on level ground, providing sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA also comes standard with a 10-meter power cable. They work perfectly with DRENO guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
