Explosion-proof design with ATEX certification
The DNA-EX series is used to pump biological liquids and sewage. Its large free passage for solids makes it ideal for treatment plants, public and private sewer systems, and the livestock industry.
Pumps in this series can be used in all hazardous areas, in accordance with the certificate available on request.
Features
All major components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, housed in an oil chamber, guarantees long product life.
Advantages of DNA-EX pumps
The DNA-EX sewage pump is an ideal solution for anyone looking for a professional product for use at home or in a small business. The DNA-EX sewage pump’s large free passage is the best alternative to pumps with a macerator, which often clogs and can cause operational problems. The large free passage beneath the impeller allows solids measuring 45 to 80 mm (depending on the model) to pass through, ensuring long-term operation without the need for intervention. The open, six-vane Vortex impellers handle even fibrous sewage with ease, while macerators act like winders. 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 years of operation in raw domestic wastewater. The connection flanges allow installation with any coupling feet with holes to DN50-80 PN10.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or the terrain geometry may sometimes require more power.
Controls
The DNA-EX sewage pump is available in two power supply versions: single-phase and three-phase. Float switches are available as separate accessories and connect to the special EMX-EX barrier (a relay in the control cabinet). To control DNA-EX pumps (except models with a built-in float switch), we recommend the simple M121 controllers M121 (230 V). Suitable control cabinets that meet ATEX requirements can also be used.
Installation methods
Thanks to the DN flange, DNA-EX pumps are often installed on coupling feet in domestic, municipal, network and stormwater pumping stations. When fitted with a suitable hose connection (an elbow with a plain end), they become portable pumps for drainage and for handling liquids with a high solids content (gravel, sand, waste). The DNA-EX 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-EX pumps have sturdy feet that protrude from the pump housing, allowing them to stand on level ground with sufficient clearance beneath the housing for water intake.
Like all DRENO sewage pumps, the DNA models also come with a 10-meter power cable as standard. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
