■ Benefits
■ Application
ARPEX series ARP-6 couplings have been specially developed
for pump drives and specifically for centrifugal pump drives.
Special care was taken to meet the requirements of API 610 and
API 671 (API = American Petroleum Institute). Power is transmitted
via close-fitting bolts and nuts from size 310-6 with conical
screw connection and plate packs in hexagonal design. Torques
of between 100 and 17000 Nm can be transmitted at a permitted
angular misalignment of 0.7°. The closed flange shape and a
compact construction permit high peripheral speeds and high
speeds. The intermediate spacer can be fitted radially without
moving the connected units.
ARPEX couplings of the ARP-6 series are outstanding for their
application-optimized construction. The two types NAN and
MCECM have been specially designed for drives with uniform to
medium loads and at the same time meet the requirements of
API 610. The type MCECM with preassembled CEC intermediate
unit can also be optionally designed to API 671. A special
catcher device serves to secure the intermediate spacer in the
event of plate breakage. Their use in potentially explosive environments
in accordance with Directive 94/9/EC is possible.
