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 (motor side in the oil chamber, impeller side in contact with the liquid), together with high-quality parts, 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 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 means that much of the solid matter does 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 ejected 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 by an external signal. To control V4 pumps, we recommend and offer professional power and control panels with relay-contactor or microprocessor control.
Installation
The most common installation method for V4 pumps is mounting on a DUTY or type B coupling foot in raw sewage pumping stations. Horizontal type A coupling feet or mobile installations on a type P stand are used less often. To lower the pump along guide rails into the pumping station tank, a suspension in the form of a stainless steel chain or stainless steel cable with suitable strength is used. It is attached to the holes in the bracket at the top of the pump, ensuring the pump remains properly balanced while being lowered. When installing the coupling foot, remember to keep the bottom of the tank flat beneath the pump; 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 flooding 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 terminals,
• 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).
