The Compatta PRO series with free passage 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, as specified in 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 pumps with free passage
Compatta PRO series pumps are a more advanced version of the domestic Compatta pumps. They are primarily distinguished by their suitability for operation in harsh conditions, including potentially explosive atmospheres. The manufacturer has ensured that the pumps have ATEX certification and come with the necessary equipment, such as a special cable with a gland and an ATEX control panel (available to order). The PRO version has just one free passage size beneath the impeller, namely 50 mm, which works perfectly with EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines from DN50 upwards.
Open six-vane Vortex impellers handle even fibrous wastewater with ease, whereas conventional grinders act like winding reels. Grinder blades quickly become blunt in wastewater, acting like wedges and blocking the pump. Sewage pumps with a free passage beneath the impeller do not have these drawbacks. The impeller’s thick walls ensure 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 sometimes requires a more powerful pump.
Controls
Compatta PRO is available in various configurations combining single- and three-phase power with control by a built-in float switch (230V only) or an external signal. For domestic applications, we recommend the simple M121 controllers M121 (230V) or M131 (400V). For more demanding users and dual-pump lifting stations, we offer professional relay-contactor power and control panels SPP and SPS.
Possible applications
With the appropriate 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, debris). Compatta PRO pumps are used for drainage in mines, transferring process water at treatment plants, and in demanding industrial conditions. The Compatta PRO has sturdy feet that extend from the pump housing, providing adequate clearance beneath the housing for water intake.
Like every DRENO wastewater pump, the Compatta PRO comes with a 10-meter power cable as standard.
