What does the model designation code mean for the ABT series?
The model designation code represents structural specifications including pump series, flow rates for both the shaft end and cover end pumps, shaft type, rotation direction, port positions, design number, and sealing levels.
What sealing level options are available for the ABT Series?
There are two main sealing levels: Sealing Level 1 uses S1 (Buna) NBR Nitrile rubber, and Sealing Level 2 utilizes S2 HNBR (Hydrogenated Nitrile Butadiene Rubber) for demanding industrial environments.
How is the rotation direction determined for these vane pumps?
The rotation is viewed directly from the shaft end of the pump. It is designated as "R" for right-hand (clockwise) rotation and "L" for left-hand (counter-clockwise) rotation.
What models are covered under the ABT double pump series installation dimensions?
Installation dimensions and port position details are provided for ABT11T, ABT21T, and ABT22T models to ensure accurate mounting and integration into industrial systems.
Where can I find the precise shaft extension parameters?
Shaft extension dimensions (such as L1-L5 lengths, DIA, and K1xK2 keyway sizes) are detailed in the Shaft Extension table for models ABT1T, ABT2T, ABT3, ABT11T, ABT21T, and ABT22T.
