Advantages of the Alpha V PRO-EX explosion-proof wastewater pumps
The Alpha V PRO-EX 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 hazardous areas. The manufacturer has provided ATEX certificates for the pumps, as well as 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 under the impeller, namely 50 mm, which works successfully with discharge pipelines from DN50 upward.
Open six-vane Vortex impellers handle even fibrous wastewater contents perfectly, while typical macerators work like winding reels. Macerator blades, which quickly become blunt in wastewater, act like wedges and block the pump. Wastewater pumps with a free passage under the impeller are free from these disadvantages. The impeller's thick walls ensure many years of operation in raw domestic and municipal 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 the use of greater power.
Control
Alpha V PRO-Ex wastewater pumps are offered without a built-in float switch. When operating in an explosion-hazardous environment, the EX GEX - ATEX float switch EX GEX - ATEX float switch in an explosion-proof version must be used. It may require protection in the control system (not supplied by Dambat) in the form of an EMS protective relay/barrier EMS - EXI / 2 relay (Ex protective barrier) for ATEX float switches
Possible applications
With a suitable hose connection, we obtain a lightweight portable pump for drainage and handling liquids with a high content of solids (gravel, sand, 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 intake.
Like every DRENO wastewater pump, the Alpha V PRO comes standard with a 10-meter power cable.
