Explosion-proof pump
Thanks to their compact size and excellent mechanical properties, Alpha V PRO-EX series pumps are ideal for pumping domestic wastewater.
Pumps can be used in all hazardous areas, in accordance with CE0477 certificate EPT 17 ATEX 2701 X, Ex II 2G [Ex db IIB T4 Gb, Ex h IIB T4 Gb, 0°≤Ta≤40°, available on request.
Specifications
All main components are made of GG20 cast iron. The mechanical and lip seals ensure the product operates correctly.
Advantages of Alpha V PRO-EX septic tank pumps with free passage
Alpha V PRO-EX series pumps are a more advanced version of domestic Alpha V pumps. This version is distinguished primarily by its suitability for operation in harsh conditions, including hazardous areas. The manufacturer has ensured that the pumps have ATEX certification and the necessary equipment, such as a special cable with a gland and an ATEX control panel (available to order). The PRO version has just one free passage size beneath the impeller, namely 50 mm, and works reliably with discharge pipelines from DN50 upwards.
Open six-vane Vortex impellers handle even wastewater containing fibrous materials with ease, whereas conventional macerators act like winding machines. Macerator blades, which 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 drawbacks. The impeller’s thick walls are built to withstand years of pumping raw domestic wastewater.
When selecting a septic tank pump, we always check the specifications of the available pipeline, as the discharge pipe diameter or the terrain geometry may sometimes require a more powerful pump.
Controls
Alpha V PRO sewage pumps are available in various versions, combining single- and three-phase power supplies with control by a built-in float (230V only) or an external signal. For domestic applications, we recommend the simple controllers M121 (230V) or M131 (400V). For more demanding users and two-pump lift stations, we offer professional relay-contactor power and control panels SPP and SPS.
Possible applications
With the right hose connection, it becomes a lightweight, portable pump for drainage and handling liquids with a high solids content (gravel, sand, debris). 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 sturdy feet extending from the pump body, providing sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the Alpha V PRO comes standard with a 10-meter power cable.
