The 2-pole V series is designed for pumping sewage containing suspended solids. Thanks to their high capacity, these pumps are used in various fields, including municipal sewer systems, industrial sewer systems, agriculture and wastewater treatment plants.
Characteristics
All major components are made of GG25 cast iron. Two separate mechanical seals (on the motor side in the oil chamber and on the impeller side in contact with the liquid), together with high-quality components, ensure excellent performance and product reliability.
Advantages of the V2 sewage pump
The two-pole VT sewage pump is a professional product for use in municipal and industrial sewer systems, as well as in specialized pumping stations. Thanks to the large space beneath its Vortex impeller, it can easily pump raw sewage containing solid and fibrous matter. Small stones, gravel and rubbish are no problem either. The multi-vane Vortex impeller resists clogging from wipes, strings and kitchen waste. The water vortex that forms beneath and around the impeller prevents much of the solid matter from coming into direct contact with it, so the impeller wears more slowly than channel impellers. The advantage of the radially expanding channels is that solid matter entering through the inlet does not get stuck in the impeller channels, but is thrown outward and travels along the pump casing wall to the throat.
Control
The V2 sewage pump is generally a three-phase model, but the 65/2/152 C.346 model is also available in a 230 V version. The pumps can only be controlled by an external signal. To control V2 pumps, we recommend the simple M121 controllers M121 (230 V) or M131 (400 V <=7.5 kW). For more demanding users and dual-pump pumping stations, we offer professional power and control panels with relay-contactor or microprocessor control. They can also send SMS notifications and provide online monitoring.
Installation
The most common way to install a V2 raw sewage pump is on a DUTY coupling foot or a type B coupling. Horizontal coupling feet, type A, or mobile installations on a type P stand are used less often. A stainless steel chain or stainless steel cable with suitable strength is used to lower the pump along the guide rails into the pumping station tank; these are attached to the holes in the bracket at the top of the pump. The manufacturer offers a special stainless steel bracket as an accessory, allowing the pump to remain properly balanced while being lowered. When installing the coupling foot, ensure that the bottom of the tank beneath the pump is flat; otherwise, cavitation may occur, causing hydraulic components to wear out faster.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber, which protects the motor from flooding if the mechanical seal behind the impeller is damaged,
• Side flange outlet allows installation on a coupling foot and easy installation of an elbow connection for a flexible hose with a clamp or quick coupling,
• T1-T2 thermal protection built into the motor winding, for connection to a suitable control panel,
• 10m H07RNF power cable with bare wire ends,
• Warranty and post-warranty service,
• 24-month warranty.
On request, special versions can be made for liquid temperatures up to 60°C with the pump fully submerged (not for continuous operation).
