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 sewage systems, and the livestock industry.
Specifications
All main components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, located in an oil chamber, guarantees a 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 free passage is the best alternative to pumps with a macerator, which often clogs and causes operating difficulties. The large free passage beneath the impeller, allowing solids from 45 to 80 mm in size (depending on the model) to pass through, ensures long-lasting operation without intervention. The open, six-vane Vortex impellers handle even fibrous sewage content with ease, whereas macerators act like winding devices. 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 do not have these drawbacks. The impeller’s thick walls ensure many 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 discharge pipe diameter or terrain geometry may sometimes require a higher-power pump.
Control
The DNA sewage 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 the simple M121 (230 V) and M131 (400 V) controllers. 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 their DN flange, DNA pumps are commonly installed on coupling feet in domestic, municipal, network and stormwater pumping stations. 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, 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 sturdy feet that extend from the pump housing, allowing them to stand on level ground while providing adequate clearance beneath the housing for water intake.
Like every DRENO sewage pump, the DNA also comes standard with a 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
