The VTH 2-pole series is designed for pumping sewage containing solids. Its high efficiency makes it suitable for use in wastewater treatment plants, industrial sewage systems, agriculture, and drainage.
Specifications
All main components are made of GG25 cast iron. Two separate mechanical seals (on the motor side in the oil chamber and on 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 sewage systems, as well as in specialized pumping stations. Thanks to the large 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 tissues, strings, and kitchen waste. The water vortex that forms beneath and around the impeller keeps many solids from coming into direct contact with it, so the impeller wears more slowly than channel impellers. The radially widening channels ensure that solids entering through the inlet do not get stuck in the impeller channels, but are expelled and travel along the pump casing wall to the outlet.
Control
VTH sewage pumps are models with a power output above 10 kW and are three-phase only, so they are controlled exclusively by external signals. To control VTH 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 and provide remote monitoring over the internet.
Installation
The most common way to install VTH pumps is mounting them on a DUTY coupling foot or a type B coupling elbow in raw wastewater pumping stations. Horizontal type A coupling feet or mobile installations on a type P stand are used less frequently. To lower the pump along guide rails into the pumping station tank, a stainless steel chain or wire rope of suitable strength is used, attached to the holes in the holder at the top of the pump to ensure it remains properly balanced as it is lowered. When installing the coupling foot, remember to keep the tank floor beneath the pump flat; otherwise, cavitation may occur and hydraulic components may wear out faster.
Features
• Vortex impeller with free passage,
• Moisture sensor in the oil chamber protects the motor from water ingress if the mechanical seal behind the impeller is damaged,
• Side flange outlet enables 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 ends,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures up to 60°C with the pump fully submerged are available to order (not for continuous operation).
