CHEMICAL PUMP

The only repairs which the chemical pump may
require is the replacement of the diaphragm or
check valves. To replace the diaphragm, unscrew
the cover from the body. When replacing the
diaphragm, lubricate the outer edges of the
diaphragm with o-ring lubricant Part #05-008035 and
reassemble. To replace the check valves, unscrew
the check valve caps. Replace the check valves and
reassemble, using new o-rings.
DO NOT attempt to re-use o-rings once the check
valves have been removed. See the Illustrated
Parts Listing for a parts breakdown on the chemical
pump.
