The VTH 2-pole series is designed for pumping wastewater containing solids. Its high efficiency makes it ideal for use in wastewater treatment plants, industrial sewage systems, agriculture, and drainage.
Characteristics
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 wastewater pumps?
The VTH two-pole wastewater pumps are professional products for use in municipal and industrial sewage systems, as well as in special pumping stations. Thanks to the large space beneath the Vortex impeller, they can easily pump raw wastewater containing solid and fibrous particles. Small stones, gravel, and waste are also no problem. The multi-blade Vortex impeller is resistant to clogging by wipes, strings, and kitchen waste. By creating a water vortex beneath and around the impeller, a significant portion of the solids 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 particles entering through the inlet do not become lodged in the impeller channels; instead, they are expelled outward and travel along the pump casing wall to the volute.
Control
VTH wastewater pumps are models with a power rating above 10 kW and are exclusively three-phase. Therefore, the pumps are controlled solely by an external signal. For controlling VTH pump operation, we recommend and offer professional power and control panels with relay-contactor or microprocessor-based control. These can also provide fault notifications via SMS and remote monitoring over the internet.
Installation
The most common method of installing VTH pumps is mounting them on a DUTY coupling foot or a type B coupling foot in raw wastewater pumping stations. Less frequently used are horizontal type A coupling feet or mobile installations on a type P stand. To lower the pump into the pumping station tank along guide rails, stainless-steel chains or stainless-steel ropes of suitable strength are used. They are attached to the holes in the handle at the top of the pump, ensuring the pump remains properly balanced during lowering. When installing the coupling foot, remember to maintain a flat tank bottom beneath the pump. Otherwise, cavitation may occur, resulting in faster wear of the hydraulic components.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber, protecting the motor from flooding in the event of damage to the mechanical seal behind the impeller,
• Side flanged outlet enables installation on a coupling foot and easy connection of an elbow fitting to 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 terminated with free leads,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures of up to 60°C with the pump fully submerged can be manufactured on request (not for continuous operation).
