Explosion-proof design with ATEX certification
The Compatta PRO series with free passage is designed for pumping municipal and industrial wastewater. Its versatility and compact size make it especially suitable for pumping domestic and residential wastewater. Pumps in this series can be used in all areas at risk of explosion, in accordance with 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 Compatta domestic pumps. They are distinguished above all by their suitability for heavy-duty operation, including in areas at risk of explosion. The manufacturer has provided ATEX certificates 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 just one free passage size beneath the impeller, namely 50 mm, which works perfectly with EASY E3.1 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 tend to wind fibers around themselves. Grinder blades quickly become blunt in sewage, acting like wedges and blocking the pump. Sewage pumps with free passage beneath the impeller do not have these drawbacks. The impeller’s thick walls are built to withstand years of pumping raw domestic wastewater.
When selecting a pump, we always check the specifications of the available pipeline, as the discharge pipe diameter or terrain layout may sometimes require a more powerful pump.
Control
Compatta PRO is available in various configurations combining single-phase and three-phase power supplies with control via a built-in float (230V only) or an external signal. For domestic applications, we recommend the simple controllers M121 (230V) or M131 (400V). For more demanding users and dual-pump pumping stations, we offer professional relay-contactor power and control panels in SPP and SPS versions.
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 drainage in mines, transferring process water at treatment plants, and in demanding industrial environments. 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 standard with a 10-meter power cable.
