Troubleshooting
Probable Cause(s)
One or more valves are seating
improperly.
Suction line is plugged or
collapsed. Clogged strainer.
The charge in the pulsation
damper is incorrect.
One or more valves are seating
improperly.
Corrective Action
Remove valve and check
for debris.
Examine suction line.
Clean strainer.
Check pressure in pulsation
dampener (20% working pressure).
Remove valve and check for
debris. Examine the valve seatings
and clean them.
Output drops and the pump is noisy.
Oil comes out of the discharge port
or oil is a milky color.
1. Always drain and flush pump before servicing or
disassembling for any reason (see instructions).
2. Always drain and flush pumps prior to returning unit
for repair.
3. Never store pumps containing hazardous chemicals.
Oil level is too low.
One or more diaphragms split.
Hazardous Substance Alert
4. Before returning pump for service/repair, drain out all
liquids and flush unit with neutralizing liquid. Then, drain
the pump. Attach tag or include written notice certifying
that this has been done. Please note that it is illegal to
ship or transport any hazardous chemicals without United
States Environmental Protection Agency Licensing.
3
Add oil to correct level (halfway up
the sight tube).
Remove manifold and heads. Drain
oil and clean crankcase of water.
Replace diaphragms, heads and
manifold. Refill with Hypro Oil
(Part No. 2160-0038).
Maintenance Instructions for All Models
Maintenance
1. After use, 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, nondetergent, SAE
30 weight oil designed to prolong pump life.
To drain oil from the pump, remove the oil drain plug,
and rotate the shaft until the oil stops flowing out. To
fill the pump with oil, slowly pour the 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.
3. For winter storage or if a freezing condition will be
encountered, flush pump with a 50/50 mixture of
water and antifreeze.

Diaphragm and Valve Replacement
I. Valve and O-Ring Replacement
1. Occasionally debris can cause the valves to not
seat properly or damage the o-rings. To check
for this problem, follow these steps.
2. Remove the pump manifold. (See parts list for
your model.) Use a 17 mm box wrench (or
adjustable wrench) to remove manifold nuts.
(Use a 13 mm for Models D160, D250.) With
manifold removed, valves can readily be
removed and checked for debris or wear. To
replace valves or o-rings, refer to parts list for
appropriate kits.
II. Diaphragm Replacement
Hypro recommends changing diaphragms every 500
hours or three months, whichever comes first.
1. Drain the oil from the pump by removing drain
plug. Rotate the shaft to remove excess oil.
2. Remove the pump manifold according to Step 2
in Section I: Valve and O-ring Replacement.
3. Use a 19 mm box wrench (or adjustable wrench)
to remove the diaphragm retaining bolt, support
washer and diaphragm. To replace the
diaphragms, order the appropriate repair kit.
See the parts list.
Figure 1. Diaphragm Replacement
4. Turn the crankshaft to bring the piston to its
upstroke to replace the diaphragm. Use the
downstroke to seat the new diaphragm into the
sleeve groove. Install retaining washer and
tighten nut.
5. Replace the pulsation dampener diaphragm by
first bleeding the air from the dampener. (See
parts list for your model.) Use a 13 mm box
wrench to remove the bolts holding the
dampener assembly together, then replace
diaphragm. Recharge dampener to 20% of
operation pressure.
6. Refill crankcase with Hypro Oil (Part No. 2160-
0038). Rotate the shaft slowly forward and
reverse to distribute oil, and fill to the proper
level.
