The Compatta PRO series with a free-flow passage 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, in accordance with the certificate available upon request.
Features
All major components are made of GG20 cast iron. The mechanical and lip seals ensure proper product operation.
Advantages of Compatta PRO free-flow pumps
Compatta PRO series pumps are a more advanced version of the domestic Compatta pumps. This version is primarily distinguished by its suitability for operation in harsh conditions, including potentially explosive atmospheres. The manufacturer has provided ATEX certification for the pumps and 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-flow passage size beneath the impeller, namely 50 mm, which works successfully with EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines from DN50 upward.
Open six-blade Vortex impellers handle even fibrous wastewater contents perfectly, whereas typical grinders act like winding machines. Grinder blades that quickly become blunt in wastewater act like wedges and block the pump. Wastewater pumps with a free-flow passage beneath the impeller are free from these disadvantages. The impeller’s thick walls ensure many years of operation in raw domestic wastewater.
When selecting a 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 greater power.
Control
Compatta PRO is available in various versions combining single- and three-phase power supplies with control by means of a built-in 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 two-pump pumping stations, we offer professional relay-and-contactor power and control switchboards: SPP and SPS.
Possible applications
With a suitable hose connection (an elbow ending in a plain end), it becomes a lightweight portable pump for dewatering and handling liquids with a high content of solid particles (gravel, sand, waste). Compatta PRO pumps are used for dewatering mines, transferring process water at wastewater treatment plants, and in demanding industrial conditions. Compatta PRO has stable feet extending from the pump body, providing sufficient clearance beneath the body for water intake.
Like every DRENO wastewater pump, Compatta PRO comes standard with a 10-meter power cable.
