The DNA series is designed for pumping biological liquids and wastewater. The large free passage for solids makes it ideal for wastewater treatment plants, public and private sewage 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, guarantees a long product life.
Advantages of DNA pumps
The DNA sewage pump is the ideal solution for those looking for a professional product for use at home or in a small business. The free passage of the DNA sewage pump is the best alternative to pumps with macerators, which often become clogged, exposing the user to operational difficulties. The large free passage under the impeller for contaminants measuring from 45 to 80 mm, depending on the model, ensures long-term operation without the need for intervention. Open six-blade Vortex impellers handle even fibrous sewage contents exceptionally well, whereas macerators act like winding devices. The blades of macerators quickly become blunt in sewage, acting like wedges and blocking the pump. Sewage pumps with such a large free passage under the impeller are free from these disadvantages. The impeller’s thick walls are suitable for many years of operation in raw domestic sewage. Connection flanges allow installation with any coupling feet featuring holes according to DN.
When selecting a pump, check the parameters of the available pipeline, as the diameter of the discharge pipe or the terrain geometry may sometimes require the use of a higher-powered pump.
Control
The DNA sewage pump is available in four versions combining single- and three-phase power supplies with control by an integrated float or an external signal. To control DNA pumps, except for versions with an integrated float, we recommend the simple M121 (230V) and M131 (400V) controllers. For more demanding users and two-pump pumping stations, we offer professional relay-and-contactor power and control panels: SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are commonly installed on coupling feet in household, municipal, network, and stormwater pumping stations. With a suitable hose connection (an elbow terminating in a plain end), they become portable pumps for drainage and for handling liquids with a high solids content, such as gravel, sand, and waste. The DNA sewage pump can be used without difficulty to water a 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 extending from the pump body, allowing them to stand on level ground with sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA comes standard with a 10-metre power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
