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 certificate CE0477 EPT 17 ATEX 2701 X, 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
Alpha V PRO-EX series pumps are a more advanced version of the domestic Alpha V pumps. This version is distinguished primarily by its suitability for operation under harsh conditions, including explosion-hazardous areas. The manufacturer has provided ATEX certification 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 upward.
Open six-blade Vortex impellers handle even fibrous wastewater contents extremely well, whereas conventional macerators act like winding machines. Macerator blades, which quickly become dull 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 are sufficient for many years of operation in raw domestic wastewater.
When selecting a septic tank pump, we always check the parameters of the available pipeline, as the diameter of the discharge pipe or the terrain geometry sometimes requires the use of a higher-power pump.
Control
Alpha V PRO septic tank pumps are available in various versions combining single- and three-phase power supplies with control by an integrated 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 lifting stations, we offer professional relay- and contactor-based power and control panels: SPP and SPS.
Possible applications
With a suitable hose connection, the pump becomes a lightweight, portable dewatering pump for working with liquids containing large amounts of solids (gravel, sand, and debris). The Alpha V PRO pump is used for dewatering mines, transferring process water at wastewater treatment plants, and operating under 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.
