The DNA series is used to pump biological liquids 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 major components are made of GG20 cast iron. Double mechanical seals in a back-to-back configuration, housed in an oil chamber, ensure a long service 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 the best alternative to pumps with a grinder, which often clog and cause operating difficulties. The large free passage beneath the impeller allows solids measuring 45 to 80 mm (depending on the model) to pass through, ensuring long-term operation without intervention. The open six-vane Vortex impellers handle even fibrous sewage content with ease, while grinders act like winders. Grinder 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 residential sewage. Connection flanges allow installation with any coupling feet with DN bolt patterns.
When selecting a pump, check the specifications of the available pipeline, as the discharge pipe diameter or the terrain layout may sometimes require a more powerful pump.
Control
The DNA sewage pump is available in four versions, combining single-phase or three-phase power with control via 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 controllers M121 (230V), as well as M131 (400V). For more demanding users and dual-pump lift stations, we offer professional relay-contactor power and control panels SPP and SPS.
Installation methods
Thanks to the 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 pumps for drainage and handling 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, and pump water from a pond or ditch to another tank. DNA pumps have stable feet that protrude from the pump body, allowing them to stand on level ground 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.
