The four-pole VT series is designed for pumping particularly heavy wastewater. Its high capacity and large free passage make it suitable for use in industry, animal husbandry, sludge transport, tanneries, and anywhere liquids containing large solids need to be pumped.
Features
All main components are made of GG25 cast iron. Two separate mechanical seals (on the motor side in the oil chamber and on 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 sewage pump?
The four-pole V4 sewage pump is a professional product for use in municipal and industrial sewer systems, as well as in special pumping stations. Thanks to the large space beneath its Vortex impeller, it can easily pump raw sewage containing solid and fibrous matter; small stones, gravel, and trash are no problem either. The multi-vane Vortex impeller resists clogging from wipes, strings, and kitchen waste. The water vortex formed beneath and around the impeller means that most solids do not come into direct contact with it, so the impeller wears more slowly than channel impellers. The advantage of the radially widening channels is that solid matter entering through the inlet does not get stuck in the impeller channels, but is ejected and travels along the pump casing wall to the throat.
Control
The V4 sewage pump is a three-phase-only model with power up to 7.5 kW, 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 control.
Installation
The most common way to install V4 pumps is on a DUTY or B type coupling foot in raw wastewater pumping stations. Less commonly used are horizontal type A coupling feet or mobile stand-mounted type P installations. To lower the pump into the pumping station tank along guide rails, use a stainless steel chain or cable of suitable strength, attached to the holes in the bracket at the top of the pump to ensure that it remains properly balanced while being lowered. When installing the coupling foot, ensure that the tank floor beneath the pump is level; otherwise, cavitation may occur and the hydraulic components may wear out faster.
Features
• Vortex impeller with unobstructed passage,
• Moisture sensor in the oil chamber protects the motor from flooding if the mechanical seal behind the impeller fails,
• Side flange outlet allows installation on a coupling foot and easy installation of an elbow connector 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 bare wire ends,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures up to 60°C with the pump fully submerged (not for continuous operation) can be made to order.
