The Compatta PRO free-passage series is designed for pumping municipal and industrial wastewater. Its flexibility and compact size make it particularly suitable for pumping domestic and residential wastewater. Pumps in this series can be used in all potentially explosive atmospheres, as specified in the certificate 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 Compatta PRO free-passage pumps
Compatta PRO series pumps are a more advanced version of Compatta domestic pumps. Above all, this version is designed for operation in demanding conditions, including potentially explosive atmospheres. 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 just one free passage size beneath the impeller, i.e. 50 mm, which works perfectly with EASY E3.1 and EASY E3.2 coupling feet, as well as discharge pipelines from DN50 upwards.
Open six-vane Vortex impellers handle even fibrous sewage perfectly, while conventional grinders act like winding machines. Grinder blades, which quickly become blunt in sewage, act like wedges and block the pump. Sewage 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 sewage.
When selecting a pump, we always check the specifications of the available pipeline, as the diameter of the discharge pipe or the terrain layout may sometimes require more power.
Controls
Compatta PRO is available in various versions combining single- and three-phase power supplies with control by a built-in float switch (230V only) or an external signal. For domestic applications, we recommend simple controllers M121 (230V) or M131 (400V). For more demanding users and dual-pump pumping stations, we offer professional relay-contactor power and control panels: SPP and SPS.
Possible applications
With a suitable hose connector (an elbow with a plain end), this lightweight, portable pump can be used for drainage and for pumping liquids with a high solids content (gravel, sand, debris). Compatta PRO pumps are used for drainage in mines, transferring process water at wastewater treatment plants, and in demanding industrial environments. Compatta PRO has sturdy feet that extend from the pump housing, providing sufficient clearance beneath the housing for water intake.
Like every DRENO wastewater pump, Compatta PRO comes standard with a 10-meter power cable.
