The Alpha V PRO sewage pump is designed for pumping liquids from municipal wastewater. Its flexible operation and compact size make it particularly suitable for pumping domestic and household wastewater.
Characteristics
All main components are made of GG20 cast iron. The mechanical and lip seals ensure the product operates correctly.
Advantages of Alpha V PRO sewage pumps with a free passage
The Alpha V PRO series pumps are a more advanced version of the domestic Alpha V pumps. This version is primarily distinguished by its suitability for operation in harsh conditions, including potentially explosive atmospheres. The manufacturer has provided ATEX certification for the pumps, along with the necessary equipment, such as a special cable with a cable gland and an ATEX control panel (available to order). The PRO version has only one free-passage size beneath the impeller—50 mm—which works successfully with discharge pipelines from DN50 upward.
Open six-blade Vortex impellers handle even fibrous wastewater content excellently, whereas typical grinders act like winding reels. Grinder blades that quickly become blunt in wastewater act like wedges and block the pump. Sewage pumps with a free passage beneath the impeller do not have these disadvantages. The impeller's thick walls are sufficient for many years of operation in raw domestic and household wastewater.
When selecting a sewage pump, we always check the parameters of the available pipeline, as the diameter of the discharge pipe or the terrain's geometry may sometimes require a higher power rating.
Control
Alpha V PRO sewage pumps are available in various versions combining single- and three-phase power supplies with control by a built-in float switch (230V only) or an external signal. For domestic applications, we recommend the simple M121 (230V) or M131 (400V) controllers. For more demanding users and two-pump pumping stations, we offer professional relay-contactor power and control cabinets: SPP and SPS.
Possible applications
With a suitable hose connection, it becomes a lightweight portable pump for drainage and for handling liquids with a high content of solids (gravel, sand, and waste). The Alpha V PRO pump is used for drainage in mines, transferring process water at wastewater treatment plants, and in demanding industrial conditions. The Alpha V PRO has stable feet extending from the pump body, providing sufficient clearance beneath the body for water inflow.
Like every DRENO sewage pump, the Alpha V PRO comes standard with a 10-meter power cable.
