Mechanism
BT and BTH series pumps are gear pumps low speed displacement fluid for medium and high viscosity fluids are used, provided that at least a certain amount of the lubrication properties , the terms of without any solids material is used in the manufacture of chemical substances is consistent .
Standard material of construction of pump chamber , the chamber cover lid and sealed bearings are gray cast iron . The steel shafts and gears with hardened and grinding , surface hardness increase is made . Shfty on bearing beds ( Sajmh s) is located , is made of bronze . Sintered bronze instead of iron can be used as an alternative option .
Shaft sealing cap sealing a wall that is made of PTFE coated fiber aramind .
Static seal between the stationary components , by adhesive or sealant or sealing is done by the washers . All materials are asbestos -free sealing .
Permissible external axial loads but no radial loads can be limited depending on the size and direction of the load is Jzbnd .
This pump flexible couplings ( compared to other couplings ) to transmit power from the engine to the pump is preferred .
Where the pumped fluid flow required to increase the temperature (such as bitumen , waxes ( beeswax ) , etc.), BTH series pumps should be used . In this model, the pump body is double walled chamber temperature is between these two .
Transmission fluid in the pump chamber through the fluid circulating in the chamber, heat or steam heater , is heated .
The area covered by the specific type of model can be specified are described below .
BT2 other pumps with structure and acid corrosion resistant ( stainless steel body and gears ) , with Carbon Bush for the bearings is presented. Working pressure of the pump is limited to Bar 5 .
BT1 to BT4 model pump casing can be made of bronze , while the possibility of gears and shafts are made of stainless steel .
The use of these pumps in case of pump fluid nature Sayndgy or corrosive high impact ( including resins, paints and oils, such as certain types of adhesives ) , a special structure is proposed under the Code No./04 the pumps are available in the size BT1 and BT7 .
In this way all pump parts that are in contact with the fluid displaced by the binding of a substrate made of Ni / Sic chemical method fragments deposited on the face of erosion and corrosion are protected . This operation longevity in comparison with the case of the standard model to be used for such fluids increases .
