The four-pole VT series is designed for pumping 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 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), along 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 municipal and industrial sewer systems, as well as specialized 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 debris are no problem either. The multi-vane Vortex impeller resists clogging from wipes, strings and kitchen waste. The water vortex that forms beneath and around the impeller keeps many solids from coming into direct contact with it, so the impeller wears more slowly than channel impellers. The radially widening channels mean that solids entering through the inlet do not get stuck in the impeller channels; instead, they are expelled and travel along the pump housing wall to the outlet.
Controls
The V4 sewage pump is a three-phase-only model with a power rating of up to 7.5 kW, so it can only be controlled using an external signal. For controlling V4 pumps, we recommend and offer professional power and control panels with relay-contactor or microprocessor-based controls. They can also send fault notifications by SMS and provide online monitoring.
Installation
The most common way to install V4 pumps is on a DUTY coupling foot or a type B coupling elbow in raw wastewater pumping stations. Less commonly used are horizontal type A coupling feet or mobile type P installations on a stand. To lower the pump along guide rails into the pumping station tank, use a suitably strong stainless steel chain or cable, attached to the holes in the bracket at the top of the pump to ensure it remains 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 faster wear of the hydraulic components.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber 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 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 designed for liquid temperatures up to 60°C with the pump fully submerged are available to order (not for continuous operation).
