They can be single - threaded and two - threaded devices with a constant flow of working fluid. They have their own characteristics in the characteristics and symbols.
Marking of this series HHBG12 - 2X (A) M:
XX - if there is, then the pump is dual - flow.
BG12 - 2 - vane pump (name).
X (A) - pump size and supply of mineral oil.
M - a modernized mechanism.
Such devices are used in regions with a temperate and cool climate.
Designed to supply hydraulic fluid to the hydraulic drive. To be made with the right rotation of the shaft. It also has its own characteristics not only in the characteristics, but also in the marking.
Explanation of the symbol XXH12 - XX (A) M:
XX - double - threaded (if there is a figure in the marking).
G12 - vane pump.
XX (A) - the consumption of mineral oil.
M - modernized.
These pumps can be with a nominal inlet pressure of 6.3 MPa and 16 MPa. In pumps where 1 + 1 is written, it means that the pump is dual - flow.
Marking NPL - X / X:
NPL - vane pump (type).
X is the working volume (measured in cm3).
X - Inlet Pressure (MPa).
They are placed and used in such a climatic modification as UHL4.
