ROEMHELD F 9.601 Hydraulic Accumulators used in hydraulic power workholding applications

• Nominal volume 13 - 750 cm³
• Maximum operating pressure 250 - 500 bar
• Hydraulic fluid: hydraulic oil
• Nominal volume: 13 - 750 cm³
• Oil volume at pmax and 22°C: 45 - 625 cm³
• Standard gas-preload pressure 40 - 160 bar
• Connections: G1/4 - G1/2
• Adm. operating temperature [°C]: -10 - +80

Liquids are more or less incompressible and therefore are not in the position to store pressure energy. For hydraulic accumulators the compressibility of nitrogen is used to store liquids. A gas-tight diaphragm separates the liquid zone from the gas zone. In the bottom of the diaphragm there is a valve disk that avoids a damage of the diaphragm if the hydraulic accumulator will be completely discharged. Nitrogen is filled in at the screw plug and provided with the required preload. For this purpose an appropriate filling and testing fixture is required.

ROEMHELD B1.590 Hydraulic Block Cylinders: block cylinder, design with tube, double acting

OBSOLETE ITEM - CONTACT HYQUIP

• Operating pressure 500 bar maximum
• Piston diameter ranges from 25 to 80 mm
• Rod diameter ranges from 16 to 50 mm
• Maximum push force ranges from 12.3 to 125.7 kN
• Strokes in mm steps: 60 - 1200 mm

The two cylinder heads in block form are connected by a HP tube, in which the piston is guided. The HP tube and the chromium-plated piston rod material are cut goods, which allows manufacturing of any piston strokes in a very short time.

ROEMHELD M8.301 Modulog Clamping Modules workpieces for manual assembly operations.

• Functioning: single acting
• Max. clamping force: 2.5 kN
• Max. clamping stroke: 5 mm
• Max. operating pressure: 500 bar
• Hose nominal diameter: ND 4

ROEMHELD D8.800 Manually Operated Hydraulic Pump with Foot Lever, Base and Pressure Gauge

• Displacement per stroke: 2 .. 8 cm³
• Oil volume: 300 .. 970 cm³
• Usable oil volume: 150 .. 750 cm³
• Hydraulic connection: G 1/4
• Pump supplied is filled with oil

Type with foot lever, base and pressure gauge In connection with our clamping elements, workpieces can be clamped economically with this clamping pump. Furthermore, this pump can be used for lifting loads, adjusting and clamping tables, as well as for other operating processes.

ROEMHELD F9.361 Hydraulic High-pressure Hoses, assembled ready for connection

• Maximum operating pressure 250/500 bar
• Nominal diameter: ND4 - ND6.3
• Port size: 8L / 8S
• Union nut: m8L / m8S
• Preferred lengths: 500 - 2500 mm

High-pressure hoses are used for energy and signal transmission in hydraulic systems. Especially when connecting movable elements, but also for the connection of hydraulic subassemblies which are not fixed on a common base, e.g. power units and clamping fixtures.

ROEMHELD D8.756 Hydraulic Intensifiers for single and double acting cylinders

• Intensification ratio 1.5 to 7.5
• Maximum operating pressure up to 500 bar
• Double acting Intensification ratio: 1:1.5 - 7.5
• Maximum flow rate: 8 - 14 l/min (low-pressure side)
• Maximum operating pressure 67 - 200 bar (low-pressure side)

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 D8.753 Single and Double acting Hydraulic Intensifiers

• Intensification ratio 1:4
• Maximum operating pressure 500/125 bar
• Single and double acting
• Intensification ration: 1:4
• Intensification volume: 21 cm³
• Maximum flow rate: 8 l/min (low-pressure side)
• Maximum operating pressure 125 - 130 bar (low-pressure side)

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 D8.010 energy-saving intermittent cycling

• Flow rate: 0.52 l/min
• Operating pressure: 30 / 200 bar bar
• Reservoir volume: approx. 3.5 l
• Usable oil volume: approx. 1.5 l
• Continuous duty: up to 60 s
• Motor rating: 0.15 kW
• Motor voltage: 400 VAC 50 Hz

ROEMHELD D8.0115 Hydraulic Power Units, ready for connection and energy-saving intermittent cycling

• Flow rate: 0.82 .. 3.51 l/min
• Operating pressure: 160/250/500 bar
• Reservoir volume: approx. 5 l
• Usable oil volume: approx. 3.2 l
• Continuous duty: up to 120 s
• Motor rating: 0.75 .. 1.1 kW
• Motor voltage: 400 VAC 50 Hz

A special feature is the mounting of pump and electric motor in the reservoir. Thus hydraulic and electric control can be arranged in a space saving way and easily accessible on the reservoir cover. The modular design enables a multitude of control variants. The radial piston pump is available with three different flow rates and operating pressures. To allow an energy-saving intermittent cycling only leakage-free poppet valves are used.
