The DNA series is designed 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.
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 long product life.
Advantages of DNA pumps
The DNA sewage pump is an ideal solution for anyone looking for a professional product for use at home or in a small business. The DNA sewage pump’s large free passage makes it the best alternative to pumps with macerators, which often clog and cause operating problems. The large free passage beneath the impeller allows contaminants 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 with ease, while macerators can wind up such material. 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 not subject to these problems. The impeller’s thick walls ensure many years of operation in untreated domestic sewage. The connection flanges allow installation with any guide rail 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 layout may sometimes require a more powerful pump.
Control
The DNA sewage pump is available in four versions, combining single- 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 (230 V), as well as M131 (400 V). For more demanding users and twin-pump stations, we offer professional relay-contactor power and control panels, models SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are often installed on guide rail couplings in domestic, municipal, network and stormwater pumping stations. With a suitable hose connection (an elbow with a plain end), they become portable dewatering pumps for liquids with a high solids content (gravel, sand, debris). The DNA wastewater pump can easily 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 sturdy feet that protrude from the pump body, allowing them to stand on a level surface with sufficient clearance beneath the body for water intake.
Like every DRENO wastewater 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.
