The Compatta PRO free-flow series is designed for pumping municipal and industrial wastewater. Its versatility and compact dimensions 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.
Characteristics
All major components are made of GG20 cast iron. The mechanical and lip seals ensure correct product operation.
Advantages of Compatta PRO free-flow pumps
Compatta PRO pumps are a more advanced version of the domestic Compatta pumps. This version is distinguished primarily by its suitability for operation in demanding conditions, including potentially explosive atmospheres. The manufacturer has provided ATEX certification for the pumps, as well as the necessary equipment, such as a special cable with a gland and an ATEX control panel (available to order). The PRO version has only one free-flow size beneath the impeller, i.e. 50 mm, which works successfully with EASY E3.1 and EASY E3.2 coupling feet, as well as discharge pipelines from DN50 upwards.
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 free 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 specifications of the available pipeline, as the diameter of the discharge pipe or the terrain geometry may sometimes require the use of a higher-power pump.
Control
Compatta PRO is available in various versions combining single- and three-phase power supplies with control by a built-in float switch (230 V only) or an external signal. For domestic applications, we recommend the simple M121 (230 V) or M131 (400 V) controllers. For more demanding users and two-pump pumping stations, we offer professional relay- and contactor-based power and control panels: SPP and SPS.
Possible applications
With a suitable hose connection (an elbow ending in a plain end), it becomes a lightweight portable pump for drainage and for handling liquids with a high solids content (gravel, sand, waste). Compatta PRO pumps are used for drainage in 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-metre power cable.
