The A4-A6 4 and 6-Potne sewage pumps are used for pumping and pressing clear liquids and sewage. The wide range and excellent hydraulic performance make these series work especially in: sewage treatment plants, sewage, animal breeding and industrial pipelines, such as at airports, in the subway, hospitals and hotels.
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.
Advantages of the pump for the A4-A6 sewage system
Four and six polar pumps DRENO For raw sewage, they are professional products for applications in network and industrial sewage systems, as well as in special pumping stations. Thanks to the large space in the rotor channel, they can easily pump raw sewage containing solid and fibrous fractions, also small stones, litter or garbage are not a problem. A single -lock closed rotor is resistant to clogging with handkerchiefs, strings or waste from the kitchen. The advantage of pumps for the sewage system with a rotor with one channel is that the permanent fractions falling through the inlet do not separate the stream in the rotor, only all content is thrown out and wanders on the wall of the body of the pump to the throat.
Control
A4 and A6 raw sewage pumps are high -power models from 10 to 60kW only three -phase, which is why pump control is carried out. We recommend and offer professional power switchgears in the relay and university or microprocessor performance to control the operation of A4 and A6 pumps. Also with notification of failure through text messages or an internet view.
Installation
The most common method of installing pumps in the sewage system is the installation on the coupling knee type AND or type B in pumping stations of raw or rainwater. Mobile installations on the rack are less often used 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.
Characteristics
• single -channel single -channel rotor with high efficiency,
• 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,
• T1-T2 thermal protection built into the engine winding, for connecting to the appropriate control panel,
• 10m h07RNF power cable ended with free clamps,
• 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).
