What a Non-Metered Nozzle Is
A non-metered oil dispensing nozzle is a manual outlet at the end of a dispensing hose. The operator opens it, oil flows, and the operator closes it when the receiving container looks full enough. There is no measuring chamber, no mechanical register or digital display, and no automatic shutoff or overfill protection built into the nozzle.
If you need a total, a batch preset, or a repeatable delivered volume, that function must come from a separate device in the line, such as a meter or a scale. The nozzle is simply the manual outlet.
Declared Specifications
| Maximum inlet pressure | 1,500 PSI (declared); this is a limit, not a recommended operating pressure |
| Fluids | Petroleum and synthetic oils; confirm specific fluids and viscosity limits at ordering |
| Flow basis | Depends on supply pressure, hose, spout restriction, viscosity, and temperature; quote nominal flow per model at ordering |
| Spout options | Straight, curved, and flexible spouts; per model, confirm at ordering |
| Inlet connection | Inlet thread per model; inlet swivel sometimes included, sometimes an accessory; confirm at ordering |
| Seals | Replaceable seals in a metal body; seal material per model, confirm at ordering |
Maximum inlet pressure describes the highest pressure the nozzle body should ever see. Recommended operating pressure is a separate, lower figure that depends on your pump, hose, and fluid. Confirm both values at ordering.
Non-Metered versus Metered
A metered nozzle contains a measuring element, either a mechanical register with rotating digits or a digital display with a reset. Some metered versions add batch control, so the operator sets a target volume and the device stops or signals at that point.
A non-metered nozzle has no register, no display, no batch setting, and no automatic shutoff. It cannot tell you how much oil left the spout. If accountability matters, put a meter elsewhere in the system and keep the nozzle as a plain manual outlet. Note also that a meter or a swivel in the line adds restriction and reduces flow.
What Actually Sets the Flow
Flow through a non-metered nozzle is a system property, not a nozzle number. Five things dominate: supply pressure from the pump, hose length and internal restriction, spout restriction, oil viscosity, and temperature. Raise the pressure and flow rises; add hose, thicken the oil, or chill it, and flow falls.
Viscosity is measured in cSt, and it changes with temperature. Give us your pump, hose, fluid, viscosity, and expected temperature, and we can state what to expect. For reference on the supply side, see our air operated oil transfer pump and 2L oil lubrication pump, and contact us for a quote with your system details.
Working with Drum Pumps
These nozzles are built to sit at the end of a dispensing hose fed by a drum pump or a bulk-transfer pump. Match the inlet connection to the hose fitting, keep the pump within the nozzle pressure limit, and confirm the pump is compatible with the fluid.
Almost any drum pump can work if the connection, pressure, and fluid match. The common failure is a mismatch: a fine inlet thread on a coarse hose fitting, or a high-pressure pump feeding a nozzle rated lower. Check the connection and the pressure before you assemble the line, and confirm fluid compatibility at ordering. For machine lubrication duty rather than bulk transfer, see the 6L oil lubrication pump.
Requesting Written Specifications
Request written specifications for the exact model you need. Tell us the pump, the hose, the fluid, the viscosity in cSt, the expected temperature, and the inlet connection you require. We will return the declared maximum inlet pressure, the recommended operating range, spout options, seal material, and nominal flow for that configuration.
Written specifications protect both sides. If a swivel or a meter will be added, say so, because both change flow. Replacement seals are available; confirm the seal kit for your model when you order.
Frequently Asked Questions
Does this nozzle measure volume?
No, it does not measure volume at all. Any total or batch control must come from a separate device.
Does it shut off automatically?
No, there is no automatic shutoff in this design. The operator opens and closes the outlet manually.
What flow should I expect?
Flow depends on your pump, hose, spout, viscosity, and temperature. We quote nominal flow per model at ordering.
Which oils can I use?
Petroleum and synthetic oils are the declared fluid range. Confirm your specific fluid and viscosity limit at ordering.
What does maximum inlet pressure mean?
It is the highest pressure the nozzle should ever see. It is not a recommended operating pressure for daily use.
Can cold heavy gear oil be dispensed?
Viscosity and temperature both matter, and cold heavy oil may flow slowly. Confirm the fluid and conditions at ordering.
Is a swivel included?
It depends on the model you choose. Confirm whether a swivel is included or sold as an accessory.
Can the nozzle be repaired?
Yes, the body is metal with replaceable seals. Confirm the correct seal kit for your model at ordering.
Does it work with any drum pump?
It works when connection, pressure, and fluid all match. Confirm those three items before you assemble the line, and contact us for a quote if unsure.
