CHAPEL hand pump P1230SV1, integrated pressure relief valve, single-acting, 5/25 cm³, 320/50 bar
CHAPEL two-stage single-acting hand pump P1230SV1 with integrated pressure relief valve. The first stage delivers a large volume while the cylinder extends without heavy load; the second stage then provides the high final pressure.
The pressure relief valve is located in the housing, so no external valve is needed. The cylinder retracts under load or spring force. When replacing, compare the connection thread and installation position with the existing unit.
