The 4-pole VT series is designed for pumping particularly heavy wastewater. Its high capacity and large free passages make this series suitable for use in industry, animal husbandry, sludge transport, tanneries, and wherever there is a need to pump liquids containing large solids.
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), along with high-quality components, ensure excellent performance and product reliability.
What are the advantages of the V4 wastewater pump?
The four-pole V4 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 space beneath the Vortex impeller, it can easily pump raw sewage containing solid and fibrous particles; small stones, gravel, and waste 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 portion of the 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 solid particles entering through the inlet do not become blocked in the impeller channels; instead, they are expelled outward and travel along the pump housing wall to the volute.
Control
The V4 wastewater pump is exclusively a three-phase model with a power rating of up to 7.5kW, so the pumps are controlled exclusively by an external signal. For controlling V4 pumps, we recommend and offer professional power and control panels with relay-contactor or microprocessor-based construction. They can also provide fault notifications via SMS and remote monitoring over the internet.
Installation
The most common method of installing V4 pumps is mounting them on a coupling foot DUTY or type B in raw wastewater pumping stations. Less commonly used are horizontal coupling feet type A or mobile installations on a stand type P. To lower the pump along guide rails into the pumping station tank, slings in the form of a stainless steel chain or stainless steel cable of suitable strength are used. They are attached to the holes in the handle at the top of the pump, ensuring that the pump remains properly balanced during lowering. When installing the coupling foot, remember to maintain a flat tank bottom beneath the pump; otherwise, cavitation cavitation may occur, leading to faster wear of the hydraulic components.
Features
• Vortex impeller with a free passage,
• Moisture sensor in the oil chamber, protecting the motor from flooding if the mechanical seal behind the impeller is damaged,
• Side flanged outlet enables installation on a coupling foot and easy installation of an elbow connection for 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 terminated with free leads,
• 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 made to order (not for continuous operation).
