Hydraulic and pneumatic-hydraulic intensifiers for single and double acting cylinders, with fixed intensification volume or continuous redelivery.
ROEMHELD D8.751 Compact Intensifieirs that convert the hydraulic pressure input into a higher pressure output.
ROEMHELD D8.753 Single and Double acting Hydraulic Intensifiers
This ROEMHELD Hydraulic Intensifier convert a hydraulic pressure on the primary side (input) into a higher pressure on the secondary side (output). This enables the use of the comparatively low pressure of machine tool hydraulics to pressurise a hydraulic cylinder with quadruple pressure.
ROEMHELD D8.756 Hydraulic Intensifiers for single and double acting cylinders
An oscillating pump piston, that will be automatically reversed in the end positions by a hydraulically-operated valve, is installed in the intensifier. The ratio of the piston areas corresponds to the intensification ratio. For unhindered flow in the low-pressure range, the pump piston will be bypassed by means of a bypass-line. A pilot-controlled check valve shuts off the high pressure.
ROEMHELD D8.757 Hydraulic intensifiers convert a low input pressure into a higher output pressure according to the intensification ratio
An oscillating pump piston, that will be automatically reversed in the end positions by a hydraulically-operated valve, is installed in the intensifier. The ratio of the piston areas corresponds to the intensification ratio. For unhindered flow in the low-pressure range, the pump piston will be bypassed by means of a bypass-line. A pilot-controlled check valve shuts off the high pressure.
ROEMHELD D8.770 Pneumatic-hydraulic intensifier cna be used as a pressure generator where live cables are not possible or suitable.
ROEMHELD Pneumatic-Hydraulic Intensifier can be used as a pressure generator where live cables are not possible or suitable. Only single-acting cylinders can be connected. The cylinder volume should utilise the working only up to 60-70% so as to have some reserve left.
