way.
Purpose of use
Purpose of use
This pump has been engineered for small transplanting and fillings and for plants test with water. The pump can work with all kind of
liquid with a maximum viscosity of 1.5 m Pas and with water solutions with PH between 7 and 1 .
MGF
MGF refuses every responsibility for damages or bad working if the pump is used incorrectly, for a purpose for which it was not
intended or is tampered.

Starting - Installation
Starting - Installation
Before starting operations, check if the pump has been labelled with serial number and technical data. Check all the optionals integrity
too. Keep package for further transports or stocking.

Hose connection: screw the high pressure hose and the suction hose (through quick connector or 1/ ” F thread) without using too
high torque.
Water plant connection: incoming water must be clean, without corrosives and, if possible, without limestone. Maximum allowed
temperature for water is 60 °C. Connection requires a hose of at least ½” (Ø 13 mm internal) and 15 bar. Shorten if possible the
connection hose and eliminate every bottleneck on the hose. Minimum flow rate is 0 L/min.
Power connection: before connecting, check if the electric plant respects safety requirements and if it is able output required power.
The plant must have safety switch and earth grounding. Before connecting, turn off the pump. Don’t connect other loads on the same
point. Using long power cords, be sure that section of every cable is right for the current flow, to avoid high temperatures and
dissipations.
Air lowing: to avoid pressure oscillation due to air inside plant, it’s due eliminating all air inside plant to allow complete water plant
filling.
Working suggestions and Warnings
Working suggestions and Warnings
Pressure regulation device w/dou le valve allows working at desired pressure efore filling the system.
•Close the tap on the high pressure hose: read pressure = 0 on the test gauge
•Turn fully counterclockwise the the pressure regulator
•Start the motor switching the main switch
•Turn the pressure regulator clockwise, until you reach the desired working pressure on the gauge on the pump (setting gauge)
•Open the tap on the pressure hose
•Fill the system
•Close the tap and stop the pump
Close “TEST” valve, as the desired pressure has een reached. In this way you’ll cut off from test the pump and all the input
plant, while you can continue checking pressure on gauge. For long time tests, you can disconnect HELP instrument from the pump and
leave only it on the building site.
Don’t leave the pump “ON” with “TEST” valve closed. After a few minutes the bypass water increases temperature and this could
damages gaskets.
Water temperature and air u les: Water temperature and air bubbles can change pressure inside plant. Consider these factors
while testing big plants with big temperature differences.
High pressure water jets can cause damages if used improperly. Avoid starting pump without connecting it to the plant.
High pressures can ring to explosions: always consider your working pressure range before starting the test on the system:
otherwise you may damage things and persons
Work always in a safe way: respect general safety instructions, don’t let that water flows inside pump, use safety shoes and glasses.
Respect electrical safety instructions: maintenance and inspections are allowed only with the pump disconnected from power net.
Don’t stress the power cord, change it if damaged. Keep dry every electric part.
Check if high pressure hoses aren’t een damaged. If necessary, change them with original spare parts. Work on them only with
the motor turned off and with pressure discharged.
Ensure always motor ventilation. Verify that motor can have right air flow from the chassis.
Check inlet filter before every test.
Change oil after 50 hours and then after 100 hours. Use MGF MGF mineral oil (see below). This maintenance timing can change with harder
working conditions.

If you don’t use the pump for a long time, and / or in low temperature countries, pump a little amount of no frost solution inside the
pump. This will ensure long life to gaskets. Before restarting pump, turn the shaft from the hole on the chassis to unblock, if necessary,
valves.
Before starting, turn manually the shaft if necessary (gaskets glued).
Troubleshooting
Troubleshooting
The pump doesn’t reach the pressure: check in order: inlet filter, air inside pump, valves, inlet connection, gaskets.

Pressure change continuously: check air inside pump or plants. Check for dirty inside pump, valves good condition. Check filter and
gaskets.
Pressure sudden decreases: check for dirty filter and valves. Then check gaskets.
Pump is noisy: check for air suctions. Clean and move valve. Clean filter. Check water temperature. Check mechanical parts, in
particular ball bearings.
Water inside oil: change oil and look for damages on gaskets and rings. High humidity may cause this inconvenience.
Water losses from head: change gaskets and rings.
Oil losses: change oil gaskets.
Switching on, there is “hum”, ut the motor doesn’t turn: immediately turn off the motor, and verify if the pump isn’t locked. Check
if voltage in the electric net is corresponding with data on the label. Remember that long power cords may cause voltage losses. Verify
voltage at the pump plug.
The motor stops suddenly: thermal protection has switched off the pump for too high temperature. Check if voltage is correct, if pump
shaft isn’t blocked or hard to turn. Wait ten minutes, then restart pump.
The motor don’t start: check electrical connections, plug and switch. If necessary, wait for thermal switch restarting.
