TYPE 1C SEAL
A fitting for 1/4 inch O.D. plastic tubing is
supplied for directing a flow of water onto the
backplate/seal area. Use cool and filtered
water.
(If product solidifies at cool
temperature, use warm or hot water.)
Required flow is approximately 5 U.S. gallons
per hour. Insert plastic hose through a hole in
top of seal guard and into water cascade
block and tighten socket head cap screws.
(Figure 13)
NOTE: Length of plastic hose between the
water cascade block and first fitting must be
enough to allow removal of impeller and
backplate assembly with hose attached.
The water cascade block must be above the
seal on the assembled backplate to flow
water onto the seal face.
NOTE: To prevent hose contact with rotating
shaft and seal parts during operation, pull
excess hose to outside of seal guard.
TYPE 4 SEAL
(Double mechanical with flush)
Attach seal flush supply to the bottom
1/4-inch pipe threaded hole in the flush
housing. Drain tubing attached to the top hole
allows moderate pressure to be supplied to
the seals and continuous flooding.
