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 sewer 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 the oil chamber, ensures a long product life.
Advantages of DNA pumps
The DNA sewage pump is the 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 macerators, which often clog and cause operating difficulties. The large free passage beneath the impeller allows solids measuring 45 to 80 mm (depending on the model) to pass through, ensuring long-lasting operation without intervention. The open, six-vane Vortex impellers handle even fibrous sewage with ease, while macerators act like winders. Macerator blades quickly become dull in sewage, acting like wedges and blocking the pump. Sewage pumps with such a large free passage beneath 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-sized holes.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or terrain layout may sometimes require a more powerful 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 controllers M121 (230V), as well as M131 (400V). For more demanding users and two-pump pumping stations, we offer professional relay-contactor power and control panels, models SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are often installed on coupling feet in domestic, municipal, network and stormwater pumping stations. When used 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 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 stable feet that protrude from the pump body, allowing them to stand on level ground while providing sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA also comes with a 10-meter power cable as standard. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
