Specifications (contd.)
Mounting
For mounting clips, rings and flanges, please see the Mounting Accessories and Options specification sheet.
Two mounting holes in the body permit bottom mounting in the 120SP series pumps. Please see the dimensional
diagrams on the following pages for further information.
The pumps should be installed with the solenoid portion of the pump pointing upwards, downwards, or in a horizon-
tal position with the outlet on top. The horizontal position with the outlet on the bottom could affect the output
accuracy.
Adjustable pumps
In cases where the dispense volume for the application is
unknown, Bio-Chem Valve offers an adjustable pump
designed to be used as an R&D tool by the instrument
design engineer to help determine the optimal dispense
setting. By turning the shell on the pump, the engineer
can compensate for the instrument’s friction losses or
pressure imbalances. Once the correct pump setting and
dispense volume have been determined, the engineer can
provide the dispense volume to the factory. This informa-
tion will be used to manufacture a factory-set (non-adjust-
able) pump specific to the application.
Aside from the adjustability of these pumps, all other specifications are identical with those stated in this product
data sheet for the same pump series.
For part numbers of the adjustable pump versions, please contact Bio-Chem Valve and Omnifit.
