The DNA series is used for pumping biological fluids and sewage. Its large free passage for solids makes it ideal for 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 an oil chamber, guarantees a long product lifespan.
Advantages of DNA pumps
The DNA sewage pump is an ideal solution for anyone looking for a professional-grade 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 the need for intervention. The open, six-vane Vortex impellers handle even fibrous sewage contents with ease, whereas 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 are designed for many years of operation in raw domestic sewage. The connection flanges allow installation with any 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 higher-powered pump.
Control
The DNA sewage pump is available in four versions, combining single- 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 (230V), as well as M131 (400V). For more demanding users and dual-pump pumping stations, we offer professional relay-contactor control panels: SPP and SPS.
Installation methods
Thanks to their DN flanges, DNA pumps are commonly installed on guide rail couplings in domestic, municipal, and network sewage pumping stations, as well as stormwater pumping stations. 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, debris). A DNA sewage pump can easily 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 stable feet that extend from the pump casing, allowing them to stand on a level surface with sufficient clearance beneath the casing for water intake.
Like every DRENO sewage pump, the DNA also comes standard with a 10-meter power cable. They work perfectly with DRENO guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
