The VTH two-pole series is designed for pumping sewage containing solid matter. Its high capacity 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), along 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 ample clearance beneath the Vortex impeller, they 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. 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 ejected and travels along the pump casing wall to the outlet.
Control
VTH sewage pumps with outputs above 10 kW are three-phase only, so they are controlled exclusively by external signals. To control VTH pumps, we recommend and offer professional power and control panels with relay-contactor or microprocessor control. They can also notify you of faults by SMS and provide monitoring over the internet.
Installation
The most common way to install VTH pumps is on a DUTY coupling foot or a type B coupling elbow in raw sewage pumping stations. Horizontal coupling feet of 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 suspension in the form of a stainless steel chain or stainless steel cable of suitable strength, attached to the holes in the handle at the top of the pump, allowing the pump to remain properly balanced while being lowered. When installing a coupling foot, remember to keep the tank floor flat beneath the pump; otherwise, cavitation may occur, accelerating wear on the hydraulic components.
Features
• Vortex impeller with a free passage,
• Moisture sensor in the oil chamber, which protects the motor from water ingress if the mechanical seal behind the impeller is damaged,
• Side flanged outlet allows installation on a coupling foot and easy installation of an elbow connection for a flexible hose using 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 terminals,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions with liquid temperatures up to 60°C can be made to order when the pump is fully submerged (not for continuous operation).
