The 2-pole V series is designed for pumping sewage containing suspended solids. Thanks to their high efficiency, these pumps are used in a range of applications, including municipal sewer systems, industrial sewer systems, agriculture, and wastewater treatment plants.
Specifications
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 fluid), 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 clearance beneath its Vortex impeller, it can easily pump raw sewage containing solid and fibrous matter. Small stones, gravel, and trash 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 keeps many solid objects from coming into direct contact with it, so the impeller wears more slowly than channel impellers. The radially expanding channels ensure that solid matter entering through the inlet does not get stuck in the impeller channels, but is expelled and carried along the pump casing wall to the throat.
Control
The V2 sewage pump is basically a three-phase model, but model 65/2/152 C.346 is also available in a 230V version. However, the pumps can only be controlled by an external signal. To control V2 pumps, we recommend simple controllers M121 (230V) or M131 (400V <=7.5kW). 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 internet access for monitoring.
Installation
The most common installation method for the V2 raw sewage pump is mounting it on a DUTY coupling foot or a type B. Horizontal type A coupling feet are used less frequently, as are mobile installations on a type P stand. Stainless steel chain or stainless steel cable slings of suitable strength are used to lower the pump along guide rails into the pumping station tank; they are attached to the holes in the handle at the top of the pump. The manufacturer offers a special stainless steel handle as an accessory to ensure the pump remains properly balanced while being lowered. When installing the coupling foot, remember to keep the bottom of the tank beneath the pump flat; otherwise, cavitation may occur, causing hydraulic components to wear faster.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber, which protects the motor from water ingress if the mechanical seal behind the impeller fails,
• The side flanged outlet allows installation on a coupling foot and easy connection of an elbow fitting to a flexible hose using a clamp or quick connector,
• T1-T2 thermal protection built into the motor winding, for connection to a suitable control panel,
• 10 m 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).
