The 2-pole V series is used for pumping sewage containing suspended solids. Thanks to their high efficiency, they are used in various areas, such as municipal sewage systems, industrial sewage systems, agriculture and sewage treatment plants.
Characteristics
All main components are made of GG25 cast iron. Two separate mechanical seals (motor side in the oil chamber, impeller side in contact with the liquid) and high-quality parts ensure excellent performance and reliability of the product.
Advantages of the V2 sewage pump
The VT two-pole sewage pump is a professional product for use in network and industrial sewage systems, as well as in special pumping stations. Thanks to the large space under the Vortex impeller, it can easily pump raw sewage containing solid and fibrous fractions, also small stones, gravel or garbage are not a problem. The multi-blade Vortex rotor is resistant to clogging with tissues, strings or kitchen waste. By creating a water vortex under and around the impeller, a significant part of the solids does not have direct contact with the impeller, which makes the impeller wear slower than in channel impellers. The advantage of radially expanding channels is that the solid fractions falling through the inlet do not get blocked in the impeller channels, but are thrown out and travel along the wall of the pump body to the throat.
Controls
The V2 sewage pump is basically a three-phase model, but the 65/2/152 C.346 model has a 230V version, and the pumps are controlled only by an external signal. We recommend simple controllers to control the operation of V2 pumps M121 (230V) or M131 (400V <=7.5kW). For more demanding users and double-pump pumping stations, we offer professional power and control switchboards in relay-contactor or microprocessor versions. Also with notification via SMS or online viewing.
Installation
The most common way to install the V2 raw sewage pump is to install it on a coupling foot DUTY or type B. Horizontal coupling feet are used less often type A or mobile installations on a stand P type. To lower the pump along the guides to the pumping station tank, slings are used in the form of a stainless chain or stainless steel cable of appropriate strength, which 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, allowing the pump to be properly balanced when lowering. When installing the coupling foot, remember to keep the bottom of the tank flat under the pump, otherwise it may cause cavitation and faster wear of hydraulic components.
Features
• Vortex impeller with free passage,
• Humidity sensor in the oil chamber, which protects the engine against flooding with water in the event of damage to the mechanical seal behind the rotor,
• Side flange outlet allows installation on a coupling foot and easy installation of an elbow connection to a flexible hose using a clamp or quick connector,
• Built-in Float controlling the pump operation and protecting against dry running,
• T1-T2 thermal protection built into the motor winding, for connection to the appropriate control panel,
• 10m H07RNF power cable with free terminals,
• Warranty and post-warranty service,
• 24-month warranty.
On request, it is possible to produce special versions with a liquid temperature of up to 60°C with the pump fully submerged (not in continuous operation).
