The Compatta PRO free-passage series is designed for pumping municipal and industrial wastewater. Its versatile use and compact size make it particularly suitable for pumping domestic and residential wastewater. Pumps in this series can be used in all potentially explosive areas, in accordance with the certificate available on request.
Specifications
All main components are made of GG20 cast iron. The mechanical and lip seals ensure the product operates correctly.
Advantages of Compatta PRO free-passage pumps
Compatta PRO series pumps are a more advanced version of Compatta domestic pumps. Above all, this version is designed to operate in demanding conditions, including potentially explosive areas. The manufacturer has ensured that the pumps are ATEX-certified and supplied with the necessary equipment, such as a special cable with a gland and an ATEX control panel (available to order). The PRO version has a single free-passage size beneath the impeller, namely 50 mm, which works perfectly with the EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines from DN50 upwards.
Open six-blade Vortex impellers handle even fibrous wastewater with ease, while conventional shredders tend to act like winders. Shredder blades quickly become blunt in wastewater, acting like wedges and blocking the pump. Wastewater pumps with a free passage beneath the impeller are not affected by these problems. 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.
Control
The 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 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, debris). Compatta PRO pumps are used for dewatering mines, transferring process water at treatment plants, and in demanding industrial conditions. The Compatta PRO has stable feet projecting from the pump body, providing sufficient clearance beneath it for water intake.
Like every DRENO sewage pump, the Compatta PRO comes standard with a 10-meter power cable.
