General Safety Information
Notes are used to notify of installation, operation, or
maintenance information that is important but not
safety related.
•
Do not pump flammable or explosive fluids
such as gasoline, fuel oil, kerosene, etc. Do not
use in explosive atmospheres. Do not pump
asphalt sealer, roofing compounds, concrete
sealers, or any two-step curing products. The
pump should only be used with liquids compatible with the pump materials. Failure to follow
this notice can result in severe personal injury
and/or property damage and will void the product warranty.
•
Never use your hand to check the condition of
hydraulic lines or hoses. If hydraulic fluid penetrates the skin, get medical attention immediately. Failure to get proper medical attention
may result in loss of limb or life. The safest way
to check hydraulic lines is by holding a piece of
cardboard next to the hydraulic line or hose.
•
The sound pressure level of the pump may
exceed 80dBA. Observe all safety precautions
when operating the pump within close proximity for extended periods by wearing hearing protectors. Extended exposure to elevated sound
levels will result in permanent loss of hearing
acuteness, tinnitus, tiredness, stress, and other
effects such as loss of balance and awareness.
Caution is used to indicate the presence of a hazard, which will or can cause minor injury or property damage if the notice is ignored.
Warning denotes that a potential hazard exists and
indicates procedures that must be followed exactly
to either eliminate or reduce the hazard, and to avoid
serious personal injury, or prevent future safety
problems with the product.
Danger is used to indicate the presence of a hazard
that will result in severe personal injury, death, or
property damage if the notice is ignored.
•
2
Verify that pump shaft rotates freely prior to
engaging the pump drive.
•
Do not pump at pressures higher than the maximum recommended pressure.
•
Operate the pump between a temperature range
of 45o to 140o F [7o to 60o C].
•
Make certain that the power source conforms to
the requirements of your equipment.
•
Provide adequate protection in guarding around
the moving parts such as shafts and pulleys.
•
Disconnect the power before servicing.
•
Release all pressure within the system before
servicing any component.
•
Drain all liquids from the system before servicing.
•
Secure the discharge line before starting the
pump. An unsecured discharge line may whip,
resulting in personal injury and/or property
damage.
•
Check all hoses for weak or worn condition
before each use. Make certain that all connections are tight and secure.
•
Periodically inspect the pump and the system
components. Perform routine maintenance as
required (see maintenance).
•
When wiring an electrically driven pump, follow
all electrical and safety codes, as well as the
most recent National Electrical Code (NEC) and
the Occupational Safety and Health Act (OSHA)
requirements.
•
Use only pipe, hose, and hose fittings rated for
maximum rated pressure of the pump or the
pressure at which the pressure relief valve is
set at. Do not use used pipe.
•
Do not use these pumps for pumping water or
other liquids for human or animal consumption.
•
Do not pressure feed pump inlet.
Hazardous Substance Alert
•
Always drain and flush pump before servicing or
disassembling for any reason (see instructions).
•
Always drain and flush pumps prior to returning
unit for repair.
•
Never store pumps containing hazardous chemicals.
•
3
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.

2. The proper selection of hose type and size is vital to optimal performance.
a. Use good quality inlet hose, compatible with the fluids
being pumped and with good elasticity to reduce inlet
water hammer or pulsation. Be sure that hose is not too
rigid but capable of operating at low vacuums without
collapsing. The diameter of the inlet hose should be at
least that of the pump inlet port size and preferably one
size larger if the inlet line is longer than 6 feet [1.8
meters].

Maintenance Instructions for All Models
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.
D30, D50, D303, D403 and D503
Remove the drain plug (2406-0023) (or 9910-770070 on
D503) and the oil sight glass covers, and rotate shaft
until the oil stops flowing out. Re-install the drain plug.
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.
3. For winter storage or if a freezing condition will be
encountered, flush the pump with a 50/50 mixture of
water and antifreeze.
To drain the oil:
D12GRGI and D252
Remove the oil fill cap, turn the pump upside down and
rotate the shaft until oil stops flowing out. (D252 gear
reduction oil requirements: use 80-90 wt. gear lube and
fill to level hole on gear reduction side.)
The bypass return outlet on all control units must be
connected directly to the tank without restrictions or
ball valves.
Valve Replacement
Occasionally debris may cause improper seating of the
valves or damage to the o-rings. To check for this problem, follow these steps.
D30, D50, D303 and D403
Remove the pump manifolds. With the manifolds
removed, the valves can easily be removed and inspected for debris and wear. Replace valves, o-rings and
manifolds.
D503
Remove valve retainers. With retainers removed, valves
and o-rings can easily be removed and inspected.
Replace valves, o-rings and valve retainers.
D12 and D252
Remove the head bolts and the head. Remove the valve
caps and the valve assemblies. Replace the valve
assemblies and o-rings, and reassemble.
Diaphragm Replacement: D12, D30, D252, D303,
D403 and D503
Change diaphragms every 500 hours or three months,
whichever comes first.

1. Drain oil from crankcase as instructed previously.
2. Remove pump head bolts and heads.
3. Remove the bolt securing the diaphragm (See
Figure 11).
Figure 11
7. Replace the pulsation dampener diaphragm by first
bleeding the air from the dampener. Remove the
bolts from the dampener cover and replace the
diaphragm. Reassemble the cover in place and
charge the dampener to 20% of the operating pressure.
4. Remove the old diaphragm and the washer (See
Figure 11).
5. Install a new diaphragm; then turn the crankshaft to
bring the piston to its down-stroke and seat the
diaphragm into the sleeve groove.
8. Refill the crankcase with Hypro oil (part number
2160-0038). Rotate the shaft to distribute the oil,
and fill to proper level.
6. Install the washer and bolts removed in steps 3 and
4.

Limited Warranty on Hypro Diaphragm Pumps
Hypro warrants to the original purchaser of its products (the “Purchaser”) that such products will be free from defects in material
and workmanship under normal use for the period of one (1) year for all products except: oil crankcase plunger pumps will be
free from defects in material and workmanship under normal use for the period of five (5) years, and accessories will be free
from defects in material and workmanship under normal use for the period of ninety (90) days. In addition, Hypro warrants to the
purchaser all forged brass pump manifolds will be free from defects in material and workmanship under normal use and from
damage resulting from environmental conditions for the life of the pump.
“Normal use” does not include use in excess of recommended maximum speeds, pressures, vacuums and temperatures, or use
requiring handling of fluids not compatible with component materials, as noted in Hypro product catalogs, technical literature, and
instructions. This warranty does not cover freight damage, freezing damage, normal wear and tear, or damage caused by
misapplication, fault, negligence, alterations, or repair that affects the performance or reliability of the product.
THIS WARRANTY IS EXCLUSIVE. HYPRO MAKES NO OTHER WARRANTY, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
Hypro’s obligation under this warranty is, at Hypro’s option, to either repair or replace the product upon return of the entire
product to the Hypro factory in accordance with the return procedures set forth below. THIS IS THE EXCLUSIVE REMEDY FOR
ANY BREACH OF WARRANTY.
IN NO EVENT SHALL HYPRO BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND,
WHETHER FOR BREACH OF ANY WARRANTY, FOR NEGLIGENCE, ON THE BASIS OF STRICT LIABILITY, OR
OTHERWISE.
Return Procedures
All pumps or products must be flushed of any chemical (ref. OSHA Section 0910.1200 (d)(e)(f)(g)(h)) and hazardous
chemicals must be labeled before being shipped* to Hypro for service or warranty consideration. Hypro reserves the right
