The DNA series is designed for pumping biological liquids and sewage. Its large free passage for solids makes it ideal for treatment plants, public and private sewer systems, and the livestock industry.
Specifications
All major components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, located in the oil chamber, guarantees a long product life.
Advantages of DNA pumps
The DNA sewage pump is an ideal choice for anyone looking for a professional-grade product for use at home or in a small business. The DNA sewage pump’s large free passage makes it an excellent alternative to grinder pumps, which often become clogged and cause operating problems. Its large free passage beneath the impeller allows solids measuring 45 to 80 mm (depending on the model) to pass through, ensuring long-lasting operation without the need for intervention. The open six-vane Vortex impellers handle even fibrous sewage with ease, whereas grinder pumps tend to wind fibers around their cutters. The 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 thick impeller walls are built to provide years of service in raw domestic wastewater. The connection flanges allow installation with any coupling foot with DN-sized bolt holes.
When selecting a pump, check the specifications of the available piping, as the discharge pipe diameter or terrain layout may sometimes require a higher-powered pump.
Control
The DNA sewage pump is available in four versions, combining single- and three-phase power with control by 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 (230V) and M131 (400V) controllers. For more demanding users and two-pump pumping stations, we offer professional relay-and-contactor power 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 fitted with a suitable hose connection (an elbow with a plain end), they can be used as portable pumps for drainage and for handling liquids with a high solids content (gravel, sand, waste). 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 body, allowing them to stand on level ground while providing 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 guide rail couplings: DUTY50, DUTY 65, DUTY 80 and B5.
