Accumulators 7250 psi max

• Extremely compact accumulator, ideal
for workholding applications
• Can also store fluid potential energy
between working cycles
• Operates comfortably at up to 7250 psi
• Choice of large or compact size
**Do not use NPT fittings
SPECIFICATIONS: Nitrogen-filled diaphragm
type accumulator. Allowable operating
temperature 15 to 175° F. Install in any
position, horizontal or vertical.
DESIGN CONSIDERATIONS:
1. Use only with Roemheld components
because all system components should be
leakfree.
2. Since a fixture’s fluid lines are sealed after
Compact Large disconnection from the power source, fluid
pressure will actually increase if fixture
temperature increases. This increase can
be quite substantial: about 80 psi per 1°F.
Be careful not to exceed 7250 psi at any
time during the machining cycle. Always
install a pressure gauge in the closed
system.
3. If the possibility of exceeding 7250 psi
exists, install a Relief Valve (see valves
section) in the system.
4. Shield accumulator if the possibility of
accidental damage exists.
