MAINTENANCE INSTRUCTIONS
1. After usage, flush the pump with clean water.
2. Hypro diaphragm pumps come with oil in the crankcase.
Hypro recommends changing oil after 40 hours of break-in
operation and every three months or 500 hours, whichever
comes first. Use Hypro oil (part number 2160-0038). Hypro
oil is a specially formulated, high-grade, non-detergent,
SAE 30 weight oil formulated to prolong pump life.
To drain the oil:
1. Remove the drain plug and the oil sight glass covers, and
rotate shaft until the oil stops flowing out. Re-install the
drain plug.
2. For DP252 and DP302 Series, Remove the oil fill cap, turn
the pump upside down and rotate the shaft until oil stops
flowing out
3. To fill the pump with oil, slowly pour oil into sight tube while
turning the pump shaft. Turning the pump shaft purges
all the air out of the crankcase. Always change oil when
replacing diaphragms.
4. For winter storage or if a freezing condition will been
countered, flush the pump with a 50/50 mixture of water
and antifreeze.
