The DNA series is used for pumping biological liquids and wastewater. 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. 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 wastewater pump is an ideal solution for anyone looking for a professional product for use at home or in a small business. The DNA wastewater pump’s unobstructed passage is the best alternative to pumps with macerators, which often clog and cause operating difficulties. The large free passage beneath the impeller accommodates solids measuring 45 to 80 mm (depending on the model), ensuring long-term operation without intervention. Open six-vane Vortex impellers handle even fibrous wastewater with ease, while macerators act like winding reels. Macerator blades quickly become blunt in wastewater, acting like wedges and blocking the pump. Wastewater pumps with such a large free passage beneath the impeller avoid these problems. The impeller’s thick walls are built to withstand years of pumping raw domestic wastewater. The connection flanges allow installation with any guide rail coupling foot with DN-pattern holes.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or terrain layout may sometimes require a more powerful pump.
Control
The DNA wastewater 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 simple M121 controllers (230 V) and M131 controllers (400 V). For more demanding users and dual-pump stations, we offer professional relay-and-contactor power and control panels: SPP and SPS.
Installation methods
Thanks to their DN flange, DNA pumps are often installed on coupling feet in domestic, municipal, network wastewater and stormwater pumping stations. When used with a suitable hose connection (an elbow with a plain end), they become portable pumps for drainage and handling liquids with a high solids content (gravel, sand, debris). A DNA wastewater pump can be used without any difficulty 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 level ground with enough clearance beneath the body for water intake.
Like every DRENO wastewater pump, the DNA also comes with a 10-meter power cable as standard. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
