Explosion-proof pump
Thanks to their compact size and excellent mechanical properties, the Alpha V PRO-EX series is ideal for pumping domestic wastewater.
The pumps can be used in all hazardous areas, in accordance with CE0477 EPT 17 ATEX 2701 X certification, 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 the domestic Alpha V pumps. This version is distinguished above all by its suitability for operation in harsh conditions, including hazardous areas. The manufacturer has ensured that the pumps are ATEX-certified and supplied with the necessary equipment, such as a special cable with a gland and an ATEX control panel (available to order). The PRO version has a single free-passage size beneath the impeller, namely 50 mm, which works reliably with discharge pipes DN50 and larger.
Open six-blade Vortex impellers handle even fibrous wastewater with ease, whereas conventional grinders act like winding reels. Grinder blades, which quickly become dull in wastewater, act like wedges and block the pump. Wastewater pumps with a free passage beneath the impeller do not have these drawbacks. The impeller’s thick walls ensure years of operation in raw domestic wastewater.
When selecting a septic tank pump, we always check the specifications of the available pipeline, as the discharge pipe diameter or terrain layout may sometimes require a more powerful pump.
Control
Alpha V PRO sewage pumps are available in various configurations combining single- and three-phase power with control via a built-in float (230V only) or an external signal. For domestic applications, we recommend the simple M121 controllers M121 (230V) or M131 (400V). For more demanding users and two-pump pumping stations, we offer professional relay-contactor power and control panels SPP and SPS.
Possible applications
With a suitable hose connector, 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 stable 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.
