The Compatta PRO series with a free passage 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 on request.
Features
All main components are made of GG20 cast iron. The mechanical and lip seals ensure correct product operation.
Advantages of Compatta PRO free-passage pumps
Compatta PRO series pumps are a more advanced version of the domestic Compatta pumps. This version is designed primarily for operation in demanding 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-passage size beneath the impeller, namely 50 mm, which works successfully with EASY E3.1 and EASY E3.2 coupling feet, as well as discharge pipelines from DN50 upward.
Open six-vane Vortex impellers handle even fibrous wastewater contents perfectly, whereas typical grinders act like winding reels. 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 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 an integrated float switch (230V only) or an external signal. For domestic applications, we recommend the simple M121 (230V) or M131 (400V) controllers. For more demanding users and dual-pump pumping stations, we offer professional relay-contactor 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 content of solids (gravel, sand, waste). Compatta PRO pumps are used for drainage in mines, transferring process water at treatment plants, and in demanding industrial conditions. Compatta PRO has sturdy feet protruding from the pump body, providing adequate clearance beneath the body for water intake.
Like every DRENO wastewater pump, Compatta PRO comes standard with a 10-metre power cable.
