The DNA series is used for pumping biological fluids 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 main 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 wide free passage is the best alternative to pumps with macerators, which often clog and cause operating problems. The large free passage beneath the impeller, which handles solids measuring 45 to 80 mm (depending on the model), ensures long-lasting operation without the need for intervention. The open, six-vane Vortex impellers handle even fibrous sewage exceptionally well, while 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 years of operation in raw domestic sewage. The connection flanges allow installation with any guide rail coupling feet with DN-pattern holes.
When selecting a pump, check the specifications of the available piping, as the diameter of the discharge pipe or the terrain’s layout may sometimes require a more powerful pump.
Control
The DNA sewage pump is available in four versions, combining single- or three-phase power 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 (230 V) and M131 (400 V) controllers. For more demanding users and two-pump pumping stations, we offer professional relay-contactor control panels: SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are often installed on guide rail couplings 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 pumping liquids with a high solids content (gravel, sand, debris). The DNA sewage 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 extend from the pump casing, allowing them to stand on level ground with enough clearance beneath the casing for water intake.
Like all DRENO sewage pumps, DNA pumps also come standard with a 10-meter power cable. They work perfectly with DRENO guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
