The DNA series is used for pumping biological fluids 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 major components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, housed in an oil chamber, ensures 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 large free passage makes it the best alternative to pumps with a macerator, which often clogs and can cause operating problems. The large free passage beneath the impeller allows solids measuring 45 to 80 mm to pass through (depending on the model), ensuring long-lasting operation without intervention. Open six-vane Vortex impellers handle even fibrous sewage content with ease, while macerators can wind up fibers. 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 do not have these drawbacks. The impeller’s thick walls are durable enough for many years of pumping raw domestic wastewater. The connection flanges allow installation with any coupling feet with DN-sized openings.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or site layout may sometimes require a more powerful pump.
Control
The DNA sewage pump is available in four versions, combining single-phase or three-phase power supply with control via 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), as well as the M131 (400 V). For more demanding users and dual-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 a popular choice for installation on guide rail couplings in domestic, municipal, and network wastewater pumping stations, as well as stormwater pumping stations. With a suitable hose connection (an elbow ending in a plain end), they become portable drainage pumps for liquids with a high solids content (gravel, sand, debris). 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 stable feet that protrude from the pump casing, allowing them to stand on level ground with sufficient clearance beneath the casing for water intake.
Like every DRENO wastewater pump, the DNA also comes with a 10-meter power cable as standard. They work perfectly with DRENO guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
