The Compatta PRO free-passage series 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 potentially explosive areas, in accordance with the certificate available on request.
Specifications
All major components are made of GG20 cast iron. 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 the Compatta household pumps. They are designed primarily for heavy-duty applications, including potentially explosive areas. The manufacturer has provided ATEX certification for the pumps, along with 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, 50 mm, which works well with EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines DN50 and larger.
Open six-vane Vortex impellers handle even fibrous wastewater with ease, whereas conventional grinders tend to wind material around themselves. Grinder blades quickly become blunt in wastewater, acting like wedges and blocking the pump. Sewage 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 discharge pipe diameter or terrain can sometimes require greater power.
Control
The Compatta PRO comes in various versions combining single- and three-phase power supplies with control by a built-in float switch (230 V only) or an external signal. For domestic applications, we recommend the simple M121 controllers M121 (230 V) or M131 (400 V). For more demanding users and dual-pump stations, we offer professional relay-contactor power and control panels SPP and SPS.
Possible applications
When used with a suitable hose connector (an elbow with a plain end), it becomes a lightweight, portable drainage pump for 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 sturdy feet extending from the pump housing, providing sufficient clearance beneath the housing for water intake.
Like every DRENO wastewater pump, the Compatta PRO comes standard with a 10-meter power cable.
