The DNA series is used for pumping 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.
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, guarantees a long product life.
Advantages of DNA pumps
The DNA sewage pump is an 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 an excellent alternative to pumps with a macerator, which often gets clogged and causes operational problems for users. The large free passage beneath the impeller allows particles 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 contents with ease, while macerators tend to wind them up. 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 sewage. The connection flanges allow installation with any guide rail coupling feet with DN-sized openings.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or the terrain geometry may sometimes require a higher-powered pump.
Control
The DNA sewage pump is available in four versions combining single-phase and three-phase power supplies 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 controller (230V), as well as the M131 controller (400V). For more demanding users and dual-pump pumping stations, we offer professional relay-contactor power and control panels, models SPP and SPS.
Installation methods
Thanks to their DN flange, DNA pumps are commonly installed on coupling feet 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 drainage pumps 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 sturdy feet extending from the pump body, allowing them to stand on a level surface with sufficient clearance beneath the body for water intake.
Like all DRENO sewage pumps, the DNA models also come standard with a 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
