CHAPEL seal kit JP20SDA, for hand pump P20SDA1
CHAPEL seal kit for single-acting double-stroke hand pumps of the SDA1 version. The kit restores a leaking pump without replacing it.
The complete type designation is decisive, not just the size: there is a separate kit for the double-acting DDA1 version of size 25. Depressurise the hydraulic circuit before opening and check the piston and sealing surfaces for scoring.
