MULTI-CHANNEL MOUNTING
I/P EASY-LOAD Pump Heads can be mounted in
tandem depending upon the torque capabilities of
the drive. A standard short shaft pump head is
required for the add-on head along with special
mounting hardware. (See Figure #5.)
See REPLACEMENT PARTS AND ACCESSORIES for
mounting hardware.
CAUTION: DO NOT OVERTIGHTEN
SCREWS OR WING NUTS.
NOTE: The I/P EASY-LOAD Pump Head can be used
in any combination with other 7019-series
Pump Heads.
NOTE: The tubing on the inside EASY-LOAD Pump
Head can be changed without removing the
outside pump head.
