Explosion-proof pump
The Alpha V PRO-EX series, thanks to its compact size and excellent mechanical properties, 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.
Characteristics
All major components are made of GG20 cast iron. The mechanical and lip seals ensure proper product operation.
Advantages of Alpha V PRO-EX septic tank pumps with free passage
The 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 demanding conditions, including explosion-hazard zones. The manufacturer has provided ATEX certificates for the pumps, as well as the necessary equipment, such as a special cable with a gland and an ATEX control panel (available to order). The PRO version has only one free-passage size beneath the impeller, namely 50 mm, which works successfully with discharge pipelines from DN50 and larger.
Open six-blade Vortex impellers handle even fibrous wastewater contents perfectly, whereas typical macerators act like winders. Macerator blades that quickly become blunt in wastewater act like wedges and block the pump. Wastewater pumps with free passage beneath the impeller are free from these disadvantages. The impeller's thick walls ensure many years of operation in raw domestic wastewater.
When selecting a septic tank pump, we always check the parameters of the available pipeline, as sometimes the diameter of the discharge pipe or the terrain geometry requires greater power.
Control
Alpha V PRO septic tank 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 M121 (230V) or M131 (400V) controllers. For more demanding users and dual-pump pumping stations, we offer professional relay-and-contactor-type power and control cabinets: SPP and SPS.
Possible applications
With a suitable hose connection, it becomes a lightweight portable pump for drainage and operation with liquids containing large amounts of solids (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 wastewater pump, the Alpha V PRO comes standard with a 10-meter power cable.
