The DNA series is used to pump 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 main components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, housed in an oil chamber, ensures a long product life.
Advantages of DNA pumps
The DNA wastewater pump is the ideal solution for anyone looking for a professional product for use at home or in a small business. The DNA wastewater pump’s free passage is the best alternative to pumps with a macerator, which often clogs and can cause operational problems. The large free passage beneath the impeller for solids measuring 45 to 80 mm (depending on the model) ensures long-lasting operation without the need for intervention. Open six-vane Vortex impellers handle even fibrous wastewater exceptionally well, while macerators act like winders. Macerator blades quickly become blunt in wastewater, acting like wedges and blocking the pump. Wastewater 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 wastewater. 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 site layout may sometimes require a more powerful pump.
Control
The DNA sewage pump is available in four versions, combining single- and three-phase power supplies with control by an integrated float switch or an external signal. To control DNA pumps (except versions with an integrated 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 relay-contactor power and control panels: SPP and SPS.
Installation Methods
Thanks to their DN flange, DNA pumps are often installed on coupling feet in domestic, municipal, network and stormwater sewage pumping stations. With a suitable hose connection (an elbow with a plain end), they become portable drainage pumps suitable for handling liquids with a high solids content (gravel, sand, waste). A 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 extend from the pump body, allowing them to stand on a level surface with sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the DNA also comes standard with a 10-meter power cable. They work perfectly with DRENO coupling feet: DUTY50, DUTY 65, DUTY 80 and B5.
