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 certificate available on request.
Specifications
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
The Compatta PRO series pumps are a more advanced version of the Compatta domestic pumps. Above all, this version is designed for operation in demanding conditions, including potentially explosive atmospheres. The manufacturer has ensured the pumps are ATEX-certified and equipped them with the necessary accessories, such as a special cable with a cable gland and an ATEX control panel (available to order). The PRO version has only one free passage size beneath the impeller, namely 50 mm, and works successfully with EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines from DN50 upwards.
Open six-blade Vortex impellers handle wastewater containing fibrous material with ease, while conventional macerators act like winding machines. Macerator blades quickly become blunt in wastewater and act like wedges, blocking the pump. Wastewater pumps with a free passage beneath the impeller do not have these drawbacks. The impeller’s thick walls are durable enough for years of pumping untreated domestic wastewater.
When selecting a pump, we always check the parameters of the available pipeline, as the discharge pipe diameter or terrain geometry sometimes requires a more powerful pump.
Controls
Compatta PRO is available in various versions combining single- and three-phase power supplies with control by a built-in float (230V only) or an external signal. For domestic applications, we recommend simple controllers M121 (230V) or M131 (400V). For more demanding users and two-pump pumping stations, we offer professional relay-contactor power and control panels SPP and SPS.
Possible applications
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 extending from the pump casing, providing sufficient clearance beneath the casing for water intake.
Like every DRENO wastewater pump, the Compatta PRO comes standard with a 10-meter power cable.
