Micro Gear And Magnetic Drive Pumps
SKQB Micro Pump
Magnetic drive micro gear pump for precise low flow duty.
View specifications →Micro Gear And Magnetic Drive Pumps
Small Gear Pump
The compact build of the micro gear family, sized to fit inside equipment rather than to stand beside it.
Overview
What This Pump Does
The small gear pump is the compact member of the magnetic drive micro pump range. It is used where the pump has to be built into a machine, a cabinet or a bench instrument and still deliver a repeatable low flow.
Duties include lubrication feed, additive dosing, coating and adhesive supply and sample preparation, all of which need a small pump that delivers the same volume every revolution.
| Applications include | ingredient dispense, point-of-use dispense, lubrication, sampling, additives, and sample preparation |

Key Benefits
Why It Fits Where Others Do Not
Small Installed Envelope
A compact head and motor make it practical to mount inside equipment without redesigning the frame.
No Seal To Service
Magnetic drive removes the gland, which is important when the pump is buried inside a machine.
Repeatable Volume
Fixed displacement per revolution keeps dosing consistent across production runs.
Material Options
PEEK gears where the liquid rules out metal to metal contact.
Application Scenarios
Where It Is Installed
Machine Lubrication
Feeding a measured lubricant stream to bearings and slides inside a machine.
Coating And Adhesive Feed
Supplying coatings, adhesives and solvents to an application head at a controlled rate.
Bench Instruments
Sample preparation and point of use dispense inside laboratory equipment.
Who It Is For
- Machine builders needing an internal pump
- Laboratory instrument manufacturers
- Production engineers automating lubricant or adhesive feed
- Integrators working in tight enclosures
Problems It Solves
No room for a standard pump
The compact assembly fits where a conventional sealed pump and its service clearance would not.
Maintenance inside a machine
Removing the seal removes the reason to open the machine on a schedule.
Inconsistent dosing between runs
Positive displacement makes the delivered volume a function of revolutions, which a controller can count.

Technical Data
Send the available envelope as well as the duty. On machine mounted pumps the space is often the binding constraint.

Compared With Other Options
| SKQB micro pump | Same principle in a larger frame. Choose this build when space rather than flow is the limit. |
|---|---|
| Peristaltic pump | A tube pump is simpler and tolerates dry running, but needs tube changes and gives pulsing flow. |
Use Guide
Building The Pump Into A Machine
Confirm The Envelope
Check head, motor and connection clearances against the frame before finalising the design.
Plan Access
Leave enough room to disconnect the ports, even though the pump has no seal to service.
Filter And Protect
Fit a suction filter and protect against dry running in the machine control logic.
Calibrate In Place
Measure delivered volume per revolution on the installed liquid and store that figure in the controller.
Answers
Small Gear Pump FAQ
How small is it?
It is the compact build of the family. Send the available space with your enquiry and we will confirm the dimensions of the head and motor.
Can it dose adhesives?
Metering applications include adhesives, coatings, lubricants and solvents. Confirm the specific product for gear material selection.
Is dry running acceptable?
No. Protect against an empty suction line in the machine control.
Can the controller count volume?
Yes. Displacement per revolution is fixed, so counted revolutions give a dosed volume once calibrated.
Are PEEK gears available on this build?
Yes, where the liquid or the application rules out metal gears.
