The following are care and maintenance instructions for the GulpTM PRO hand pump series.
The 36” and 21” GulpTM PRO as well as the Syringe models can be completely disassembled and
cleaned after each use particularly when used in excessively muddy, gravely water.
Cleaning and Care Instructions
The top and bottom portions of the hand-pumps can be loosened in counter-clockwise manner

hands are wet, dry them before attempting this task.

Verify the wiper seal is in good condition and is not worn. Replace as needed. Lastly before
threading the bottom cap onto the cylinder, verify the flapper-valve is flat and not curled.
Re-assemble both ends and hand-tighten only. Your GulpTM PRO is now ready to work as hard as
you.
