ON Functioning in by pass conditions is only allowed for brief periods 2 minutes maximum Whenever a particular installation carries the risk of functioning in by pass mode for longer periods of time it is necessary that the by passed flow not be recirculated inside the pump but be returned to the suction tank 4 4 Fluid Allowed Fluids Not Allowed ALLOWED Oil with a Viscosity from 50 to 2000 Cst at working temperature NOT ALLOWED RELATED DANGER Gasoline Petrol Fire explosion Fire explosion Inflammable liquids with PM lt 55 C Water Oxidation of the pump Liquid food products Contamination of same Corrosive Chemicals Corrosion of the pump Injury to people Solvents Fire explosion Damage to gasket seals ATTENTION The gear pump is sensitive to those polluted fluid DO NOT deliver the fluid contained too much impurity 5 MOVING AND TRANSPORTING Given the limited weight and size of the pumps See dimensions and weights moving the pumps does not require the use of lifting equipment The pumps are carefully packed before shipment On receipt check the packing materials and store in a dry place 6 INSTALLATION 6 1 Preliminary Inspection Check that the machine has not suffered any damage during its transport or warehousing Clean the inlet and outlet openings with care removing any dust or packing residue Make sure that the motor shaft turns freely Check that
5. ative Humidity max 90 ATTENTION The temperature limits indicated are applied to the pump components and must be respected to avoid possible damage or malfunction It is understood nevertheless that for a given oil the real functioning temperature range also depends on the variability of the viscosity of the oil itself with the temperature Specifically The minimum temperature allowed 10 C could cause the viscosity of some oils to greatly exceed the maximum allowed with the consequence that the static torque required during the starting of the pump would be excessive risking overload and damage to the pump The maximum temperature allowed 60 C could on the other hand cause the viscosity of some oils to drop well below the minimum allowed causing a degradation in performance with obvious reductions in flow rate as the back pressure increases 4 2 Electrical Power Depending on the model the pump must be fed by single phase alternating current whose nominal values are those indicated in the Table of paragraph 3 1 Electrical information The maximum acceptable variations from the electrical parameter are Voltage 5 of the nominal value Frequency 2 of the nominal value ATTENTION Electrical power from lines with values outside the limits indicated can cause damage to the electrical components 4 3 Working Cycle Under normal operating conditions they can function continuously with no limitations ATTENTI
6. eration described above must be repeated The priming phase may last from several seconds to a few minutes depending on the characteristics of the system If this phase is excessively prolonged stop the pump and verify That the pump is not running completely dry That the suction hose guarantees against air infiltration and is correctly immersed in the fluid to be drawn That any filters installed are not blocked That the priming height is not greater than 2M That the delivery hose allows for the easy evacuation of the air When priming has occurred after reattaching the delivery gun verify that the pump is functioning within the anticipated ranges possibly checking 1 that under conditions of maximum flow the energy drawn by the motor falls within the values indicated on the label 2 that the back pressure in the delivery line does not exceed the values indicated in paragraph 6 4 SUCTION amp DELIVERY LINES 8 EVERY DAY USE 8 1 Manual Operation 1 Before starting the pump make sure that the ultimate shut off device delivery gun or line valve is closed 2 Turn the on switch 3 Make sure that the tank is filled with a quantity of oil greater than the quantity to be supplied running dry could damage the pump ATTENTION Never start the pump by simply inserting the plug in the outlet 4 Open the delivery valve or activate the delivery gun gripping it securely 5 Close the delivery gun or the line val

8. riming height can reach 2M when the suction hose is empty and the pump is filled by the fluid So during this period the height between the pump amp fluid should be less than 2M If exceed this height it would be better to assemble a foot valve or use a larger diameter suction hose It is suggested never install a pump over 3M height 7 INITIAL START UP The gear type oil pumps are self priming and therefore able to draw oil from the tank even when the suction hose is empty on start up The priming height distance between the surface of the oil and the inlet opening must not exceed 2M WARNING Wetting the pump Before starting the pump wet the inside of the pump body with oil through the inlet and outlet openings If the pump is already installed the wetting operation can be performed by unscrewing the threaded plug of the inlet opening not in use by filling the internal chamber with oil and screwing in the plug paying attention to the O ring seal If no foot valve is installed it is advisable to leave the purge valve always open so that once the device is re started again it is ready to purge the air present in the suction tube Please consider that during the operation a small part of oil re circulates in the tank If a foot valve is installed close the air purge valve by turning it clockwise so that no oil circulates in the tank If the foot valve seal is not perfectly tight the suction tube may be emptied and the purging op
