The DNA series is used for pumping biological liquids and sewage. The large free passage for solids makes it ideal for wastewater treatment plants, public and private sewage systems, as well as in the animal husbandry industry.
Features
All main components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, placed in an oil chamber, ensures long product durability.
Advantages of DNA Pumps
The DNA sewage pump is an ideal solution for those looking for a professional product for home or small business applications. The free passage of the DNA sewage pump is the best alternative to pumps with a macerator device, which often gets clogged, exposing the user to operational difficulties. Large free passage Under the impeller, contaminants ranging in size from 45 to 80 mm (depending on the model) ensure long-lasting operation without the need for intervention. Open six-blade Vortex-type impellers handle even fibrous sewage contents excellently, whereas grinders act like spools. Rapidly dulling grinder blades in sewage act like wedges and block the pump. Sewage pumps with such a large free passage under the impeller are free from such flaws. Thick impeller walls are sufficient for many years of operation in raw residential sewage. Connection flanges allow installation with any coupling bases that have holes according to DN.
When selecting a pump, the parameters of the available pipeline should be checked, as sometimes the diameter of the discharge pipe or the terrain geometry requires the use of higher power.
Control
The DNA sewage pump has four versions, which are a combination of single-phase and three-phase power supply and built-in control float switch and an external signal. For controlling the operation of DNA pumps (except versions with built-in float switch) we recommend simple controllers M121 (230 V), as well as M131 (400 V). For more demanding users and two-pump pumping stations, we offer professional power and control switchboards in relay-contactor design SPP and SPS.
Installation methods
Thanks to the DN flange, DNA pumps are often installed on coupling feet in domestic, municipal, network and rainwater sewage pumping stations. By using an appropriate hose connection (elbow with a bare end), we obtain a portable pump for drainage and working with liquids with a high solids content (gravel, sand, garbage). With a DNA sewage pump, we can easily water a garden with rainwater, drain a flooded garage or basement, or pump water from a pond or ditch to another tank. DNA pumps have stable legs sticking out of the pump body, on which they can stand on a level surface that provides adequate clearance under the body for water supply.
Like any sewage pump DRENO, DNA also has a 10-meter power cord as standard. They work perfectly with coupling feet DRENO: DUTY50, DUTY 65, DUTY 80 i B5.
