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 main 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 large free passage makes it an excellent alternative to pumps with macerators, which often become clogged and cause operating problems for users. The large free passage beneath the impeller allows solids ranging in size from 45 to 80 mm (depending on the model) to pass through, ensuring long-term operation without intervention. Open six-vane Vortex impellers handle even fibrous wastewater content with ease, while macerators act like winding devices. Macerator blades, which quickly become blunt in wastewater, act like wedges and block the pump. Wastewater pumps with such a large free passage beneath the impeller are not subject to these problems. The impeller’s thick walls ensure years of operation in raw domestic wastewater. 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 the terrain layout 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) and M131 (400 V). For more demanding users and two-pump pumping stations, we offer professional power and control panels with relay-contactor control SPP and SPS.
Installation methods
Thanks to their DN flange, DNA pumps are often installed on coupling feet in domestic, municipal and network wastewater pumping stations, as well as 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, rubbish). A DNA wastewater pump can be used 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 extending from the pump housing, allowing them to stand on level ground with sufficient clearance beneath the housing for water intake.
Like every DRENO wastewater pump, the DNA also comes with a standard 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
