The four-pole VT series is designed to pump particularly heavy wastewater. Its high capacity and large free passages make it suitable for use in industry, animal husbandry, sludge transport, tanneries and anywhere liquids containing large solids need to be pumped.
Specifications
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 use in municipal and industrial sewer systems, as well as in specialized pumping stations. Thanks to the generous space beneath its Vortex impeller, it can easily pump raw sewage containing solid and fibrous matter. Small stones, gravel and debris are no problem either. The multi-vane Vortex impeller resists clogging from tissues, strings and kitchen waste. The water vortex that forms beneath and around the impeller means that most solids do not come into direct contact with it, so it wears more slowly than channel impellers. The advantage of the radially expanding channels is that solid matter entering through the inlet does not get stuck in the impeller channels. Instead, it is thrown outward and travels along the pump casing wall to the volute.
Control
The V4 wastewater pump is a three-phase-only model with a power rating of up to 7.5 kW, so the pumps are controlled exclusively by an external signal. To control V4 pumps, we recommend and offer professional power and control panels with relay-contactor or microprocessor control. They can also send fault notifications by SMS and provide online monitoring.
Installation
The most common method of installing V4 pumps is mounting them on a DUTY coupling foot or a type B coupling foot in raw wastewater pumping stations. Less common are horizontal type A coupling feet or mobile installations on a type P stand. To lower the pump into the pumping station tank along guide rails, slings made of stainless steel chain or stainless steel cable of suitable strength are used. They attach to the holes in the bracket at the top of the pump, allowing it to remain properly balanced while being lowered. When installing the coupling foot, make sure the tank bottom beneath the pump is flat; otherwise, cavitation may occur, causing the hydraulic components to wear out 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 is damaged,
• Side flange outlet allows installation on a coupling foot and easy installation of an elbow connection for a flexible hose with a 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 with free ends,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures up to 60°C with the pump fully submerged can be made to order (not for continuous operation).
