The DNA series is used for pumping biological liquids and sewage. Its large free passage for solids makes it ideal for wastewater treatment plants, public and private sewage systems, and the livestock industry.
Specifications
All main components are made of GG20 cast iron. Double mechanical seals in a back-to-back configuration, housed in an oil chamber, guarantee 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 a grinder, which often gets clogged, causing operating problems. The large free passage below the impeller, for solids ranging from 45 to 80 mm (depending on the model), ensures long-lasting operation without the need for intervention. Open six-vane Vortex impellers handle fibrous sewage content with ease, while grinders act like winding reels. Grinder blades quickly become blunt in sewage, acting like wedges and blocking the pump. Sewage pumps with such a large free passage below the impeller are free from 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 geometry may sometimes require a more powerful pump.
Control
The DNA wastewater pump is available in four versions combining single-phase 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 the simple M121 controllers M121 (230 V), as well as M131 (400 V). For more demanding users and two-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 often installed on coupling feet 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 can be used as portable pumps for drainage and 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 sturdy feet that extend from the pump housing, allowing them to stand on level ground with enough clearance beneath the housing for water intake.
Like every DRENO sewage pump, the DNA also comes standard with a 10-meter power cable. It works perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
