The 4-pole VT series is designed to pump particularly challenging sewage. 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.
Specifications
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), 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 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 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 the impeller 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, but is thrown outward and travels along the pump casing wall to the outlet.
Control
The V4 sewage pump is a three-phase-only model with a power rating of up to 7.5 kW, so the pumps are controlled exclusively via an external signal. To monitor V4 pump operation, we recommend and offer professional power and control panels with relay-contactor or microprocessor control. These can also send fault notifications by SMS or provide online monitoring.
Installation
The most common installation method for V4 pumps is mounting on a DUTY or type B coupling foot in raw wastewater pumping stations. Horizontal coupling feet type A or mobile installations on a type P stand are used less frequently. To lower the pump along guide rails into the pumping station tank, use a stainless steel chain or stainless steel cable of adequate strength, attached to the holes in the bracket at the top of the pump to ensure the pump remains properly balanced while being lowered. When installing the coupling foot, ensure that the bottom of the tank beneath the pump is flat; otherwise, cavitation may occur and hydraulic components may wear out faster.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber, which protects the motor against 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 connector,
• 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.
On request, special versions can be made for liquid temperatures up to 60°C with the pump fully submerged (not for continuous operation).
