1. OPERATING ENVIRONMENTAL CONDITIONS
Temperature：Min 14°F (-10°C) / Max +140°F (+60°C)
Relative Humidity: Max 90%
The temperature limits should be applied to the pump components and must be respected to avoid possible damage or malfunction.
Nevertheless, it should be understood that for a given oil, the real functioning temperature range also depends on the variability of the viscosity of the oil itself with different temperatures. Specifically:
At temperatures below 14°F, the viscosity of some oils can greatly exceed the maximum allowed by this pump, which will cause that the static torque required to start the pump would be excessive, and the pump may overload and suffer damage.
At temperatures above +140°F, on the other hand, the viscosity of some oils can drop well below the minimum allowed by this pump, causing back pressure increases, which can lead to degradation of pump performance, with obvious reductions in flow rate.
2. ELECTRICAL POWER SUPPLY
The AC pump must be supplied by a single-phase alternating current line whose nominal values are shown in the table TECHNICAL SPECIFICATIONS above. The maximum acceptable variations from the electrical parameters are:
Voltage: ± 5% of the nominal value (115 Volts).
Frequency: ± 2% of the nominal value (60Hz)
Power supplied from lines with values outside the indicated limits can damage the electrical components.
3. WORKING CYCLE
Under normal operating conditions they can function continuously with no limitations.
WARNING: DO NOT KEEP THE PUMP WORK IN BYPASS CONDITION MORE THAN 2 MINUTES.
Whenever a particular installation carries the risk of functioning in bypass mode for longer periods of time, it is necessary to return the bypassed flow to the suction tank; do not recirculate inside the pump.
4. FLUID ALLOWED / FLUIDS NOT ALLOWED
ALLOWED: Oil with a Viscosity from 500 to 2000 Cst (at working temperature)
Inflammable liquids with PM < 55℃
Liquid food products
Fire - explosion
Fire - explosion
Oxidation of the pump
Corrosion of the pump
Injury to people
Fire – explosion
Damage to gasket seals
The gear pump is sensitive to polluted fluids; DO NOT deliver fluids with impurities.
1. PRELIMINARY INSPECTION
Check that the pump has not suffered any damage during transport.
Clean the inlet and outlet openings with care, removing any dust or packing residue.
Make sure that the motor shaft turns freely.
Check that the electrical information corresponds with what is shown on the label.
2. MECHANICAL INSTALLATION
The gear pumps can be installed in the following ways: a. On an horizontal base b. With the pump body upwards c. With pump body aside
DO NOT install the pump vertically with the pump body downwards.
DO NOT install the pump in places with inadequate ventilation.
If absolutely necessary, install a foot valve and fill the suction tube with oil during the first priming phase.
Fix the pump using screws of a diameter suitable for the provided holes.
3. HYDRAULIC CONNECTION
Before connection, make sure that the hoses and the suction tank are free of dirt and thread residue that could damage the pump and its accessories.
Always install a metal mesh filter in the suction hose.
Before connecting the delivery hose, partially fill the pump body with oil to avoid the pump running dry during the priming phase.
Minimum nominal recommended diameter: 1in.
Use a hose suitable for functioning under suction pressure.
Minimum nominal recommended diameter: 1in.
1. Hoses and/or line components unsuitable for use with oil or with inadequate nominal pressures can cause damage to objects or people, as well as pollution.
2. Use oil-resistant pipe sealant or Teflon® Tape on all pipe threads.
3. Check all the connections before each use. Tighten them if necessary. Loosening of the connections
(threaded connections, flanging, gasket seals) can cause serious ecological and safety problems.
4. SUCTION AND DELIVERY LINES
The proper pump should be chosen considering the viscosity of the oil to be pumped and the characteristics of the system attached to the delivery of the pump. The improper application of the oil viscosity and the characteristics of the system could create unexpected large back pressure, which may cause the (partial) opening of the pump bypass and consequently reduce the flow rate.
It is recommended to use shorter tubing and/or tubing with larger diameter to reduce system resistance, so that the pump would function equally to the viscosity of the oil being pumped.
The gear-type oil pumps are characterized by excellent suction capacity. In fact, the characteristic flow rate/ back pressure curve remains unchanged even at high pump suction pressure values.
The pump will prime to a height of 6.5 feet (2 meters) when the suction hose is empty and the pump is filled with the fluid. On tanks with a suction height over 6.5 feet, a foot valve may be required on the bottom of the suction tube to hold the fluid in the tube. Do not install the pump with a height higher than 9.8 feet (3 meters), or the pump will lose its prime.
WARNING: In the case that the suction tank is installed higher than the pump installation, it is recommended to install an anti-siphon valve to prevent accidental diesel fuel leaks. Care should be taken during the installation process in order to control back pressure.
The gear-type oil pumps are self-priming and therefore, able to draw oil from the tank even when the suction hose is empty during startup.
Always wet the inside of the pump body with oil through the inlet and outlet openings before starting the pump.
If the pump is installed before being wetted, unscrew the threaded plug of the inlet opening which are not in use, fill the internal chamber with oil and then screw in the plug. During the operations, pay attention to the
If no foot valve is applied, it is advisable to leave the purge valve open at all times to make sure the air present in the suction hose is purged once the device is restarted again. During the operation, make sure there is always a small part of oil recirculating in the tank.
If a foot valve is applied, close the air purge valve by turning it clockwise to make sure no oil circulates in the tank. Make sure the foot valve seal performs well.
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 is preventing 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 6.5 feet (2 meters).
That the delivery hose allows for the easy evacuation of 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 below the values indicated on the label.
2) that the back pressure in the delivery line does not exceed the values.
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)
WARNING: 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 valve to stop delivery. The pump will immediately enter by-pass mode.
WARNING: Running in by-pass mode with the delivery closed is only allowed for brief periods (2 minutes maximum).
6) Stop the pump.
The pumps are designed and constructed to require a minimum of maintenance.
On a weekly basis, check that the tubing joints have not loosened, to avoid any leakage.
On a monthly basis, check the pump body and keep it clean of any impurities.
On a monthly basis, check and keep the pump filter clean and any other filters installed.
On a monthly basis, check that the electric power supply cables are in good condition.
Under normal working conditions the noise emission from all models does not exceed the value of 70 db at a distance of 1 meter from the electric pump.
