ENCLOSURE RATING
NEMA 4X Constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental
contact with enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow,
windblown dust, splashing water, and hose-directed water; and that will be undamaged by external formation
of ice on enclosure.
IP66 No ingress of dust; complete protection against contact. Water projected in powerful jets against enclosure
from any direction shall have no harmful effects.
This pump complies to the Machinery Directive 98/37/EC, BS, EN 60204-1, Low Voltage Directive
73/23/EC BS EN 61010-1, EMC Directive 89/336/EC, BS EN 50081-1/BS EN 50082-1.

5.1 Mounting Location
1. Choose an area located near the chemical supply tank, chemical injection point, and electrical supply. Also,
choose an area where the pump can be easily serviced.
2. Finding a secure surface and using the provided mounting hardware, mount the pump close to the injection
point. Keep the inlet (suction) and outlet (discharge) tubing as short as possible. Longer discharge tubing
increases back pressure at pump head.
NOTE: Mounting the pump lower than the chemical container will gravity-feed chemical into it. This “flooded
suction” installation will reduce output error due to increased suction lift. A shut-off valve, pinch-clamp, or
other means to halt gravity-feed to the pump must be installed during servicing.
NOTE: Install a back flow prevention check valve at the discharge side of the pump to prevent the system fluid
from flowing back through pump during pump maintenance.
NOTE: It is recommended to have a pressure relief valve at the discharge side of the of pump.
5.0 INSTALLATION
All diagrams are strictly for guideline purposes only. Always consult an expert before installing
metering pump on specialized systems. Metering pump should be serviced by qualified persons
only.
Always wear protective clothing, face shield, safety glasses and gloves when working on or near
your metering pump. Additional precautions should be taken depending on solution being
pumped. Refer to MSDS precautions from your solution supplier.
Risk of chemical overdose. Be certain pump does not overdose chemical during backwash and
periods of no flow in circulation system.
Be sure that installation does not constitute a cross connection with drinking water supply.
Check your local plumbing codes.
The pump should be serviced by qualified persons only. If equipment is used in a manner not
specified in this manual, the protection provided by the equipment may be impaired.
The pump should be supplied by an isolating transformer or RCD (operating current less or
equal 30 mA).

Risk of electric shock – cord connected models are supplied with a grounding conductor and
grounding-type attachment plug. To reduce risk of electric shock, be certain that it is connected only
to a properly grounded, grounding-type receptacle.
>Use the voltage for which the power cord is rated.
>Do not strap together control (input/output) cables and power cables.
>When there is a power interruption, the pump, which has an auto-restart feature, will restore the pump to the
operating state it was in when the power was lost.
>POWER: 115V60Hz (0.6A max.), 220V50Hz (0.3A max.), 230V60Hz (0.3A max.), 230V50Hz (0.3A max.),
240V50Hz (0.3A max.)
NOTE: Contact a licensed electrician when there is doubt regarding the electrical installation.
Electrical connections and grounding (earthing) must conform to local wiring codes.
9.0 POWER CONNECTIONS
Ensure to connect the pump to the proper supply voltage. Using the incorrect voltage will damage
the pump and may result in injury. The voltage requirements is printed on the pump serial label.

10.0 OUTPUT ADJUSTMENT
The speed of the pumping mechanism is adjustable from 0.01 to 100 % motor speed (0.01 RPM to 100 RPM).
11.0 DFD (Diaphragm Failure Detection)
The MD1 is equipped with a Diaphragm Failure Detection System which is designed to stop pump and provide an
output alarm in event diaphragm should rupture and chemical enters pump head.
This system is capable of detecting presence of a large number of chemicals including Sodium Hypochlorite
(Chlorine), Hydrochloric (muriatic) Acid, Sodium Hydroxide, and many others. System will not be triggered by
water (rain, condensation, etc.) or lubricants.
If system has detected chemical, pump diaphragm must be replaced and pump head must be thoroughly cleaned.
Failure to clean pump head will void warranty.
If DFD alarm occurs, pump will stop, close an alarm output, and screen will flash DFD with an alarm icon.

Prior to service, pump clean water through pump and suction / discharge line to remove
chemical.
Always wear protective clothing, face shield, safety glasses and gloves when working on or

being pumped. Refer to MSDS precautions from your solution supplier.

12.0 Pump Maintenance
12.1 Routine Inspection and Maintenance
Pump requires very little maintenance. However, pump and all accessories should be checked weekly. This is
especially important when pumping chemicals. Inspect all components for signs of leaking, swelling, cracking,
discoloration or corrosion. Replace worn or damaged components immediately.
Cracking, crazing, discoloration during first week of operation are signs of severe chemical attack. If this occurs,
immediately remove chemical from pump. Determine which parts are being attacked and replace them with parts
that have been manufactured using more suitable materials. Manufacturer does not assume responsibility for
damage to pump that has been caused by chemical attack.
12.2 Cleaning Pump
Pump will require occasional cleaning, especially Injection fitting, Foot Valve / Strainer, and pump head valves.
Frequency will depend on type and severity of service.
]Inspect and replace pump head valves as required.
]Periodically clean injection / check valve assembly, especially when injecting fluids that calcify such as sodium
hypochlorite. These lime deposits and other build ups can clog fitting, increase back pressure and interfere with
check valve operation.
]Periodically clean suction strainer.
]Periodically inspect pump housing (enclosure) for chemical attack. Protect pump housing from continuous
exposure to chemicals, such as drips or fumes from surrounding equipment and plumbing.
12.3 Replacing the Pump Diaphragm
]When changing the diaphragm, the pump head chamber and pump head cover should be wiped free of any dirt
and debris. The pump stroke must be FORWARD when installing the diaphragm, and BACK when installing
and tightening the pump head.
] When replacing the pump diaphragm, note the order of parts per the illustration below:
