The VT 4-tribal series is used to press particularly heavy sewage liquids. High performance and large flights mean that this series is suitable for use in industry, zootechnics, in sludge transport, in tannery and wherever there is a need to pump liquid containing large solid bodies.
Characteristic
All main elements are made of gg25 cast iron. Two separate mechanical seals (engine page in the oil chamber, the rotor page in contact with liquid) and high quality parts ensure excellent operation and reliability of the product.
What are the v4 sewage pump
The four -speed V4 sewage pump is a professional product for applications in network and industrial sewage system, as well as in special pumping stations. Thanks to the large space under the Vortex rotor, it can easily pump raw sewage containing solid and fibrous fractions, also small stones, gravel or garbage are not a problem. The multi -colored Vortex rotor is resistant to clogging with handkerchiefs, strings or waste from the kitchen. By the formation of a water vortex under and around the rotor, a significant part of the solids does not have direct contact with the rotor, which makes the rotor wear slower than in channel rotors. The advantage of radially expanding channels is that the permanent fractions falling through the inlet do not block in the rotor channels, but are thrown out and wander the wall of the body of the pump to the throat.
Control
The V4 sewage pump is mainly a three -phase model with a capacity of up to 7.5kW, but also single -phase pumps with up to 1.5kW, which is why three -phase pump control is carried out only by an external signal and a single -phase pumps of an external signal or built -in control swimmer. We recommend and offer professional power switchgears in the transmission - contactor or microprocessor performance for the operation of V4 pumps.
Installation
The most commonly used method of installation of V4 pumps is the installation on the coupling foot Long or type B in raw sewage pumping stations. Horizontal coupling feet are less commonly used type AND or mobile installations on the stand type P. For leaving the guides into the pumping station, a suspension in the form of a stainless chain or a stainless stainless stand with appropriate strength is used, which are attached to the holes in the handle on the pump mountain, allowing for the correct pump balance when leaving. When installing the coupling foot, remember to keep the flat bottom of the tank under the pump, otherwise there may be a phenomenon cavitation and faster wear of hydraulic components.
Characteristics
• Vortex rotor with free flight,
• moisture sensor in the oil chamber, which protects the engine against flooding with water in the event of damage to the mechanical seal behind the rotor,
• Side flange outlet allows you to install on the coupling foot and easy installation of a knee connection to a flexible hose for a clamping band or a quick coupling,
• built -in Float pump controls and protecting against dry work,
• T1-T2 thermal protection built into the engine winding, for connecting to the appropriate control panel,
• 10m H07RNF power cable ended with a start box,
• Warranty and post -warranty service,
• 24 months warranty.
On order, it is possible to make special versions with a liquid temperature up to 60 ° C with a completely immersed pump (not in continuous operation).
