Explosion-proof design with ATEX certification
The Compatta PRO free-passage series is designed for pumping municipal and industrial wastewater. Its versatility 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, in accordance with the certification available upon request.
Features
All major 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 the Compatta domestic pumps. Their main distinguishing feature is that they are designed to operate in harsh conditions, including potentially explosive atmospheres. The manufacturer has ensured that the pumps have ATEX certification and come with the necessary equipment, such as a special cable with a cable gland and an ATEX control panel (available to order). The PRO version has just one free-passage size beneath the impeller, namely 50 mm, which works seamlessly with EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines from DN50 upwards.
Open six-blade Vortex impellers handle even fibrous sewage exceptionally well, while conventional shredders act like winding mechanisms. Shredder blades quickly become blunt in sewage, acting like wedges and blocking the pump. Sewage pumps with free passage beneath the impeller do not have these drawbacks. The impeller’s thick walls ensure years of service in raw domestic sewage.
When selecting a pump, we always check the specifications of the available pipeline, as the discharge pipe diameter or site topography may sometimes require a more powerful pump.
Control
Compatta PRO is available in various versions combining single- and three-phase power with control by a built-in float (230V only) or an external signal. For domestic applications, we recommend the simple controllers M121 (230V) or M131 (400V). For more demanding users and dual-pump pumping stations, we offer professional power and control panels with relay-contactor control SPP and SPS.
Possible applications
When used with a suitable hose connection (an elbow with a plain end), it becomes a lightweight, portable pump for drainage and handling liquids with a high solids content (gravel, sand, waste). Compatta PRO pumps are used for drainage in mines, transferring process water at treatment plants, and in demanding industrial conditions. The Compatta PRO has stable feet protruding from the pump body, providing sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the Compatta PRO comes with a 10-meter power cable as standard.
