The VTH 2-pole series is designed for pumping sewage containing solid matter. Its high efficiency makes it ideal for use in wastewater treatment plants, industrial sewer systems, agriculture, and drainage.
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 VTH sewage pumps?
VTH two-pole sewage pumps are professional products for use in municipal and industrial sewer systems, as well as in specialized pumping stations. Thanks to the large space beneath the Vortex impeller, they can easily pump raw sewage containing solid and fibrous matter. Small stones, gravel, and trash are no problem either. The multi-vane Vortex impeller is resistant to clogging from tissues, string, and kitchen waste. As a water vortex forms beneath and around the impeller, 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 expelled and travels along the pump casing wall to the volute.
Control
VTH sewage pumps are models with a power output above 10 kW and are exclusively three-phase, so they are controlled only by an external signal. To monitor the operation of VTH pumps, we recommend and offer professional power and control panels with relay-contactor or microprocessor control. They can also send fault notifications via SMS or provide online monitoring.
Installation
The most common way to install VTH pumps is on a DUTY coupling foot or a type B coupling foot in raw wastewater pumping stations. Horizontal type A coupling feet are used less often, as are mobile type P stand installations. To lower the pump along guide rails into the pumping station tank, a stainless steel chain or stainless steel cable of suitable strength is used. It is attached to the holes in the bracket at the top of the pump, allowing the pump to remain properly balanced while being lowered. When installing the coupling foot, make sure the tank floor beneath the pump is flat; otherwise, cavitation may occur and hydraulic components may wear out more quickly.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber protects the motor from 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 unterminated 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.
