The V 2-pole series is designed for pumping wastewater containing suspended solids. Thanks to their high efficiency, these pumps are used in various areas, such as municipal sewage systems, industrial sewage systems, agriculture, and wastewater treatment plants.
Characteristics
All main components are made of GG25 cast iron. Two separate mechanical seals (the motor side in the oil chamber and the impeller side in contact with the liquid), together with high-quality components, ensure excellent performance and product reliability.
Advantages of the V2 wastewater pump
The VT two-pole wastewater pump is a professional product for use in municipal and industrial sewage systems, as well as in special pumping stations. Thanks to the large clearance beneath the Vortex impeller, it can pump raw wastewater containing solid and fibrous particles without difficulty; small stones, gravel, and debris are also not a problem. The multi-blade Vortex impeller is resistant to clogging by wipes, strings, and kitchen waste. By creating a water vortex beneath and around the impeller, a significant proportion of solids does not come into direct contact with the impeller, so it wears more slowly than channel impellers. The advantage of the radially expanding channels is that solids entering through the inlet do not become blocked in the impeller channels, but are expelled outward and travel along the pump casing wall to the volute.
Control
The V2 wastewater pump is essentially a three-phase model, but model 65/2/152 C.346 is also available in a 230V version. Pump control is carried out exclusively via an external signal. For controlling V2 pumps, we recommend simple M121 (230V) or M131 (400V <=7,5kW) controllers. For more demanding users and two-pump pumping stations, we offer professional power and control panels with relay-contactor or microprocessor control. They can also provide SMS notifications and internet monitoring.
Installation
The most commonly used method of installing the V2 raw wastewater pump is mounting it on a DUTY coupling foot or a type B coupling elbow. Horizontal type A coupling feet or mobile installations on a type P stand are used less frequently. To lower the pump into the pumping station tank along guide rails, a stainless-steel chain or stainless-steel cable of suitable strength is used, attached to the holes in the handle on top of the pump. The manufacturer offers a special stainless-steel handle as an accessory, allowing the pump to remain properly balanced during lowering. When installing the coupling foot, remember to maintain a flat tank bottom beneath the pump; otherwise, cavitation may occur, leading to faster wear of the hydraulic components.
Features
• Free-passage Vortex impeller,
• Moisture sensor in the oil chamber, protecting the motor against flooding if the mechanical seal behind the impeller is damaged,
• Side flanged outlet enables installation on a coupling foot and easy connection of an elbow fitting to a flexible hose using a hose 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 free terminals,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures of up to 60°C with the pump fully submerged can be manufactured to order (not for continuous operation).
