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 sewage systems, and the livestock industry.
Features
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 long product life.
Advantages of DNA pumps
The DNA wastewater pump is an 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 macerators, which often clog and cause operational difficulties. The large free passage beneath the impeller handles solids ranging from 45 to 80 mm (depending on the model), ensuring long-term operation without intervention. The open, six-vane Vortex impellers handle even fibrous wastewater content with ease, while macerators act like winding mechanisms. 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 do not have these drawbacks. The impeller’s thick walls are built to withstand years of pumping 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 the terrain geometry may sometimes require more power.
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 dual-pump pumping stations, we offer professional relay-contactor control panels: 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. When fitted with a suitable hose connection (an elbow with a plain end), they become portable drainage pumps suitable for liquids with a high solids content (gravel, sand, debris). A 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 sturdy feet extending from the pump housing, allowing them to stand on a level surface with adequate clearance beneath the housing for water intake.
Like all DRENO sewage pumps, 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.
