Explosion-proof design with ATEX certification
The Compatta PRO series with a free passage is designed for pumping municipal and industrial wastewater. Its flexibility 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 on request.
Characteristics
All major components are made of GG20 cast iron. The mechanical and lip seals ensure the proper operation of the product.
Advantages of Compatta PRO free-passage pumps
Compatta PRO series pumps are an advanced version of Compatta domestic pumps. This version is distinguished primarily by its suitability for operation in demanding conditions, including potentially explosive atmospheres. The manufacturer has provided ATEX certificates for the pumps, as well as essential 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-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 perform excellently even with fibrous wastewater content, whereas typical grinders operate like winding machines. Grinder blades that quickly become blunt in wastewater act like wedges and block the pump. Wastewater pumps with a free passage beneath the impeller are free from these drawbacks. The impeller’s thick walls are sufficient for many years of operation in untreated 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 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 (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 panels: SPP and SPS.
Possible applications
With a suitable hose connection (an elbow ending in a plain end), the pump becomes a lightweight portable pump for drainage and handling liquids with a high solids content (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-metre power cable.
