Explosion-proof pump
The Alpha V PRO-EX series, thanks to its small size and excellent mechanical properties, is ideal for pumping domestic sewage.
The pumps can be used in all potentially explosive atmospheres, in accordance with the CE0477 EPT 17 ATEX 2701
Characteristics
All main components are made of GG20 cast iron. Mechanical and lip seals guarantee proper operation of the product.
Advantages of Alpha V PRO-EX free passage septic tank pumps
Alpha V PRO-EX series pumps are a more advanced version of home pumps Alpha V. This version is distinguished primarily by its intended use in difficult conditions, including potentially explosive atmospheres. The manufacturer took care of ATEX certificates for the pumps and the necessary equipment, such as a special cable with a gland and an ATEX control panel (available on request). The PRO version has only one size of free passage under the impeller, i.e. 50 mm, which successfully works with pressure pipelines from DN50 upwards.
Open six-blade Vortex impellers cope perfectly even with fibrous wastewater contents, while typical shredders act as winders. Shredder blades, which quickly become blunt in sewage, act like wedges and block the pump. Sewage pumps with free passage under the impeller are free from such disadvantages. The thick walls of the rotor are sufficient for many years of operation in raw sewage of domestic origin.
When selecting a septic tank pump, we always check the parameters of the available pipeline because sometimes the diameter of the discharge pipe or the geometry of the area requires the use of higher power.
Controls
Alpha V PRO septic tank pumps have various versions that are a combination of single- and three-phase power supply and built-in control float switch (only 230V) and an external signal. For home use, we recommend simple controllers M121 (230V) or M131 (400V). For more demanding users and double-pump pumping stations, we offer professional power and control switchboards in relay-contactor design SPP i SPS.
Possible uses
Using the appropriate hose connection, we obtain a light, portable pump for drainage and working with liquids with a high solids content (gravel, sand, garbage). The Alpha V PRO pump is used for drainage in mines, transfer of process water at treatment plants and in difficult industrial conditions. Alpha V PRO has stable legs protruding from the pump body, which provide adequate clearance under the body for water supply.
Like any sewage pump DRENO, Alpha V PRO has a 10-meter power cord as standard.
