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 anywhere there is a need to pump liquids containing large solids.
Characteristics
All major 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.
What are the advantages of the V4 wastewater pump?
The four-pole V4 wastewater pump is a professional product for municipal and industrial sewer systems, as well as special pumping stations. Thanks to the large space beneath the Vortex impeller, it can easily pump raw wastewater containing solid and fibrous fractions; small stones, gravel, and debris are also no problem. The multi-vane 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 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 fractions entering through the inlet do not become blocked in the impeller channels, but are expelled outward and travel along the pump housing wall to the suction inlet.
Control
The V4 wastewater pump is exclusively a three-phase model with a power rating of up to 7.5 kW, so the pumps are controlled solely by an external signal. For controlling V4 pumps, we recommend and offer professional power and control panels with relay-contactor or microprocessor-based systems. These 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 DUTY or type B coupling foot 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 consisting of a stainless-steel chain or stainless-steel cable of suitable strength are used. They are attached to the openings in the handle at the top of the pump, ensuring proper balance while lowering it. When installing the coupling foot, remember to maintain a flat tank bottom beneath the pump; otherwise, cavitation may occur cavitation and the hydraulic components may wear more quickly.
Features
• Vortex impeller with a free passage,
• Moisture sensor in the oil chamber, protecting the motor against flooding if the mechanical seal behind the impeller is damaged,
• Side flanged outlet enables mounting on a coupling foot and easy installation of an elbow connection for a flexible hose with a hose clamp or quick coupling,
• T1-T2 thermal protection built into the motor winding, for connection to a suitable control panel,
• 10 m H07RNF power cable terminated with free leads,
• Warranty and post-warranty service,
• 24-month warranty.
By special order, special versions can be manufactured for liquid temperatures of up to 60°C with the pump fully submerged (not for continuous operation).
