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.
Characteristics
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
The Compatta PRO series pumps are a more advanced version of the domestic Compatta pumps. Above all, this version is designed for operation in harsh conditions, including potentially explosive atmospheres. 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 just one free passage size beneath the impeller, namely 50mm, which works perfectly with EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines from DN50 upwards.
Open six-blade Vortex impellers handle even fibrous sewage exceptionally well, whereas conventional grinders act like winding devices. Grinder blades that quickly become blunt in sewage act like wedges and block the pump. Sewage pumps with free passage beneath the impeller do not have these drawbacks. The impeller's thick walls are sufficient for years of operation in raw domestic wastewater.
When selecting a pump, we always check the specifications of the available pipeline, as the discharge pipe diameter or the terrain sometimes requires more power.
Control
Compatta PRO is available in various versions, combining single- and three-phase power with control via a built-in float switch (230V only) or an external signal. For domestic applications, we recommend simple controllers M121 (230V) or M131 (400V). For more demanding users and dual-pump pumping stations, we offer professional relay-contactor 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 harsh industrial environments. The Compatta PRO has sturdy feet that protrude from the pump body, providing sufficient clearance beneath the body for water intake.
Like every DRENO sewage pump, the Compatta PRO comes standard with a 10-meter power cable.
